Can You Paint Over Drylok? Best Drylok Painting and Care Tips 2022

Can you paint over drylok? That’s a question from one of my readers!

Here’s what I want to tell those painters with similar concerns regarding the painting of drylok. Please read on…

Concrete surfaces are naturally porous and hence susceptible to moisture.

As such, the moisture can influence mold growth, cracking, bubbling, and even scale down the surfaces’ lifespan.

Fortunately, there is a means of preventing all these issues. And that’s by using drylok paints.

Drylok paints are designed explicitly to protect surfaces periodically prone to moisture. Even so, can you paint over drylok? 

Yes, it’s possible to paint over drylok. Mostly, painting over drylok will require latex or acrylic paints. But, you should only paint once the basal coats dry. 

Moisture penetration can be bad news for your drylok so choosing a drylok paint will help your surface greatly.

This product offers a barrier to the encroaching water and eliminates the breeding conditions for mold and mildew.

Remember, metal and wood are exceptions to drylok paint. It won’t hold up well as you would expect if used on these surfaces. 

Can You Apply Drylok Over Old Drylok? 

Yes, you can apply drylok over old drylok provided the old layer is not peeling.

For the drylok to act as an effective surface waterproofer, it would help if it penetrated the pores of a surface.

As soon as drylok starts to peel, it becomes risky to apply a new layer over it. Instead, you should remove it entirely and apply a new one.

Can You Apply Drylok Over Existing Paint? 

When you apply drylok over existing paint, the drylok will lose its waterproofing abilities. So why is drylok losing its ability to resist water? 

Well, the paint prevents the drylok from penetrating the surface.

Once the chemical components cannot pass the paint barrier, it becomes less effective when it comes into contact with moisture or water.

How Many Coats of Drylok Should I do? 

For guaranteed coverage and waterproofing, 2 coats of drylok are enough. Be sure to allow the first coat to dry to touch before proceeding to the second coat.

2 hours of drying time is enough between the coats of drylok.

Ideally, you can apply the coats using a brush or a roller.

Add an extra coat if you inspect and notice any leaking after applying two coats.

Doing this helps to seal the pores left out in the previous coatings. 

Can I Paint Over Drylok Floor and Wall?

Does Drylok Cause Mold?

Drylok provides an ‘inert coating,’ which prevents mold or mildew growth.

Furthermore,  Drylok Extreme has an additive called ‘mildewcide’ which further acts to prevent the potential for mold or mildew to grow on the surface under paint.

For improved protection against mold and mildew, you can choose to apply a coat of mold-killing primer on the surface with mold signs. 

How Good Is Drylok Paint? 

It can be overly tough to deal with mold growth, cracks, and bubbles on concrete surfaces.

The continual effect of such issues merges to compromise your surrounding structurally.

Fortunately, there is a remedy to these constraints by using drylok paints.

This product has had a positive reputation over the years in delivering impeccable results. 

Drylok paint can penetrate solid surfaces and expand to form a non-porous barrier.

That’s a bonus you can count on, unlike conventional paints that attach loosely and peel off if exposed to immense water pressure. 

How Long Does Drylok Paint Last? 

Indeed this is a common question with drylok paints. First, I will say that its lifespan is based on how well you utilize this product.

If you apply it per the instructions, it will run for over ten years, even under the most demanding conditions.

For example, the drylok extreme waterproofer can withstand 15 years of extreme traffic, whereas the drylok floor and wall waterproofer is guaranteed for seven years. 

Interestingly, this duration is not limited. It can either surpass the suggested limit or succumb due to improper prep. 

Can You Use a Roller With Drylok?

Even though a stiff bristle brush is a better pick for accessing all the crevices, a roller can also be your next choice.

However, you may want to back brush your first coat to avoid imperfections.

Doing this enables the paint to pave through the pores and pinholes.

You can apply an additional coat with either a brush or roller based on your preference. 

How Do You Prepare Walls for Drylok? 

If moisture invades your walls, you can combat it using drylok paint.

This item impedes the encroaching water and deters the breeding condition for mildew and mold growth.

But before applying the paint, you must begin by preparing the walls for a decent job. 

It is a preliminary step, requiring greater focus and proper preparation.

However, be sure not to disregard this step since moisture can remain an ongoing challenge. 

Reports suggest that vinegar kills a huge percentage of mold types.

But cleaning your walls with vinegar won’t seal the porous holes to deter continual visits of mold issues.

As an alternative, I prefer using a wire brush to wipe out paint, dust, and dirt from the wall’s surface.

Of course, following this trajectory means you ought to wear a dust mask to avoid breathing loose particles. 

So unless you use a wire brush to clean the walls, the drylok won’t adhere to the surface.

You may also consider wiping out the powdery deposits that remain on the surface.

However, before proceeding any further, wear rubber gloves and protective glasses. You then apply a small coat of Etch to prep the wall surface for painting.

After that, permit the walls to dry entirely. Following these steps sets your wall surfaces fit for painting.

Here’s how to prepare your surface for drylok:

How to Apply Drylok

Concrete and masonry surfaces are bound to be the strongest materials in home advancements. And that’s owing to their unparalleled strength and durability.

However, regardless of the massive strength and enduring traits, these surfaces are far from unbeatable. 

Moisture makes concrete surfaces porous and relatively vulnerable to mold, leaks, and cracks.

Therefore, to prevent such instances, it is imperative to waterproof your concrete surfaces. You can achieve that by applying drylok paint.

In addition, I have designed a step-by-step guideline to help you prevent your home from moisture effects. Read on for more clarity. 

Things You Will Need.

  • Wire brush.
  • Dust mask.
  • Safety eyeglasses. 
  • Drylok Etch.
  • Chisel.
  • Rubber gloves.
  • Drylok fast plug.
  • Putty knife. 
  • ¾ inch nap paints roller and nylon bristle paintbrush. 
  • Drylok. 

Once you are equipped with the abovementioned items, you are set to start the job. 

Step 1: Prep the Work Area and the Surface.

Similar to various painting applications, preparing a surface is never an option but a must.

But before this, wear safety glasses and a mask to prevent inhaling harsh materials elicited while cleaning.

Then, ensure your workspace is properly ventilated and has precise airflow. 

Now, begin with a wire brush to scrub off the surface you intend to paint. That helps to peel off all loose mortar, dust, efflorescence, and dirt. 

Note: it’s interesting to know that efflorescence is very tough to wipe out by brushing.

I recommend you wear vinyl gloves and put undiluted vinegar into a sponge.

You then scrub the surface to a point where the material dissolves entirely. 

You may also want to use a suitable means of removing the existing paint. Sand-blasting will be your first choice for peeling off the old paint. 

  • You must be aware that drylok doesn’t work well with oil-based paints. It only holds up to the surface but won’t be practical in waterproofing the wall. 

Step 2: Using Drylok Fast Plug to Seal Joints

Next, you need to assess the walls you intend to paint for possible gaps, holes, cracks, or other openings that need sealing.

If any, use a drylok fast plug to fill and fix the openings. Drylok fast plugs can fix up holes amid water flow. 

But before sealing the holes, wet the area to be patched into an inverted “V” shape.

Doing this allows the patch to blend with the surface, and the fast plug dries hastily. 

Step 3: Start to Apply Drylok Masonry Paint to the Surface.

Once you are through the integral steps, ensure the surface and air temp surpass 50 degrees Fahrenheit.

Next, take your paint and give it a good stir to form a uniform solution. Then using a bristle brush, start to distribute even strokes of paint across the surface.

You will need to be careful with your strokes to fill in all cracks, gaps, and crevices on the surface.

The material will look white and milky but don’t worry, it’s normal. It will later dry transparently. 

Give your first coat ample time to dry and hold up to the surface. 


  • For best results, doing this project on a rain-free day is good. 
  • A gallon of drylok is sufficient to cover 75 to 100 square feet of your wall’s surface. But these figures vary based on the surface’s porosity. Note that the surface will need at least two coats for better results. 

Step 4: Adding an Extra Coat 

Drylok paint is formulated to provide an impediment against moisture.

You can apply it using your preferred option, either a brush or a roller.

That tells you it should be applied carefully, unlike the typical paints. Be sure to spend more time filling all the openings on the surface as you apply the paint.

After your first coat is dry to touch, add a second coat of paint and do gentle strokes. 

The second coat is paramount since it guarantees effective waterproofing. 

  • Remember to dispose of the empty containers after the close of operation.

Is Drylok Better than Kilz? 

Kilz is a waterproofing paint with a low odor and has materials that aid in water infiltration.

It also offers an enduring and decorative finish on concrete and masonry surfaces. But does it transcend the efficacy of drylok paint?

These two products are both excellent basement waterproofing paints. But Kilz is rated more superior than drylok.

You will notice that drylok is primarily designed for masonry surfaces, but kilz can excel well on almost all surfaces. 

However, both products can withstand high water pressure. So rest assured that your painted surface won’t peel off easily with time. 

Does Drylok Stop Water? 

Do you want to protect your new construction or existing masonry from water? Then it’s worth giving it a try to drylok paint.

Drylok extreme masonry waterproofer is certified to block water flow on your surface.

Its chemical construction penetrates your walls’ openings and creates a solid barrier to stop the water.

Not to mention the adherence ability of this product is unmatchable compared to its prevalent counterparts. 

Can You Paint Drylok to a Wet Wall?

Drylok is an integral paint formula, and you can apply it on wet basement walls to boost their durability.

However, don’t be prompted to paint if the surface is extremely wet. Instead, you can begin by running your fingertips over the surface to certify how wet it is.

Besides being suitable for basements, drylok is still a choice for many in various other application projects.

What Is the Difference Between Drylok Concrete Protector and Drylok Clear Masonry Waterproofer?

The two aforementioned are different with regards to their use.

Drylok concrete protector encompasses a curing element; you can use it on both new and old concrete.

The default purpose of this option is to control dust on the concrete surface.

On the other hand, drylok clear masonry waterproofers block water from paving through your concrete floors.

The chemical compounds in this product guarantee an impenetrable barrier against moisture.

Both products are relatively functional in their specific field of expertise. So it’s upon you to know when to use each of them in the right project.

Will Drylok Prevent Mold? 

Drylok paint stands out for various reasons. It is known to be a versatile option on various porous surfaces.

However, people often ask, will it deter mold?

The response to this question varies based on the version of paint you use. The original drylok is not a better pick in this case.

I recommend you go for the extreme drylok paint since it’s meant to endure tough conditions. 

Thanks to the chemical ingredients in this drylok extreme paint can hinder mold growth. However, the ability to prevent mold growth is not 100% guaranteed. 

  • To paint drylok over mold, be sure to employ a good quality acrylic latex paint. 

Can You Put Kilz Over Drylok?

Yes, you can paint kilz over drylok. In addition, you don’t have to scrape off the existing drylok since it is a perfect barrier against water penetration. 

Does Drylok Paint Need Primer? 

There is no denying that drylok paint has outstanding traits that you won’t find easily on other paints.

One of these impeccable traits is that it doesn’t need a primer for better adherence.

Therefore, suppose you apply coats of drylok latex waterproofer; you don’t have to prime.

The drylok itself will serve as a perfect primer for all good quality paints. 

How Soon Can You Paint Drylok Fast Plug? 

Drylok fast plug can be referred to as a quick setting hydraulic cement. It can set within 3 to 5 minutes if mixed to a thick consistency.

Once set, it deters water from flowing through the openings on the surface. And just like mortar, drylok fast plug hardens very quickly. 

So then, how soon can you paint the drylok fast plug? You can paint the drylok fast plug as soon as it’s fully dry. Check out below how you can arrive at this point. 

The first step involves tidying up the surface you want to apply the cement.

Next, clean the walls or floor thoroughly to wipe out dust, dirt, and the rest.

If there is any mold, use a certified detergent with considerable bleach to scrub it off.

Not to forget, remove the existing paint, if any, to enhance better adherence. 

Once you are ready, mix a considerable amount of drylok fast plug with water in a bucket.

Next, mix the solution with a trowel regarding the manufacturer’s instructions.

And then, take a spray bottle and dampen the openings since cement holds up well on wet surfaces.

Next, apply the drylok fast plug into the gaps and ensure the cement is merely 5″ underneath the cracks’ base. 

Repeat the same thing using a trowel to smear an additional coat of drylok plug to the gaps.

And then smoothen the layer, and leave it to dry for nearly 24 hours before painting.

Once it’s entirely dry, you may want to paint the surface depending on your preferred color. 

What’s the Great Benefit of Drylok Masonry Waterproofer Over Powdered Waterproof Coatings? 

As the strategies in this guide imply, drylok paint is no exception in how it works.

This product is relatively easy to use due to its glossy and creamy consistency. And since it adheres effortlessly to any surface, it saves you plenty of time.

This option doesn’t have to pre-wet the surface before painting. Just apply it to slightly damp or dry areas. 

Can Drylok Masonry Waterproofer Be Applied on Floors?

There are different versions of drylok, and not all are sanctioned to serve similar purposes.

For instance, drylok extreme and drylok original are not designed for floor surfaces.

Instead, use drylok floor and wall waterproofer on walls and floors.

Such paints endure heavy foot traffic, and you can use them before applying latex-based adhesives. 

Can You Use Drylok Masonry Waterproofer Over Wood, Terra Cota, or Metal?

I don’t recommend using DRYLOK® Masonry Waterproofer on anything other than bare masonry and concrete surfaces

Even so, you can apply it to porous terra cotta, concrete, cement, and stucco.

Will Drylok Etch Help Deter Efflorescence? 

Efflorescence is a result of salt deposits established within the block’s confines. If left unattended, it can remain a persistent issue.

Fortunately, you can prevent efflorescence using a drylok Etch, which impedes it from reoccurring. 

Can I Apply Drylok to Other Surfaces? 

Are you wondering if drylok paint can serve other purposes besides concrete and masonry surfaces? It’s possible.

Interestingly, you can use drylok paint to waterproof fish ponds.

However, as the manufacturer recommends, you should let the paint cure for at least 5 to 7 days.

Note that the cure time mentioned earlier is essential since it ensures that the volatile processing aids evaporate completely.  

If you rush before the cure time ends, it can produce excess foaming, primarily if water is added. As such, this affects the quality of water in the fish pond.

Does Drylok Smell? 

Sealing concrete surfaces and basement walls is unwelcoming due to waterproofing paints’ odor.

However, there is a latex-based waterproofer that eliminates strong odor. And at the same time, it retains its sealing potential.

Nevertheless, it is imperative to consider odor since basements walls are sealed from the interior. And that means there is poor ventilation. 

Drylok paint is known to dry faster, so you only have to tolerate three hours to apply a second coat.

Besides being odorless, drylok paint is also non-flammable. Mind you; the applied tools are easy to clean after use. You only need soap and water to cleanse them. 

Signs that Your Basement Needs Drylok Paint

Waterproofing is very important to basements since they are likely exposed to high traffic.

However, small things can cause insidious problems to your basements.

In this guide, we take the plunge into some signs that prove your basements need painting.

Check out below. 

  • The damp, stale odor

If you notice an unbearable smell within the confines of your basement, then there is a prevalent issue.

Water seepage might have occurred for a long time, and I suggest this is the ripe time to seal it with drylok paint. 

  • Signs of Mold

Mold is always a concern for many homeowners. Even though it almost goes without saying, you should never disregard mold infestation in your surrounding.

Regardless of the mold species, do not fail to attend to any mold signs.

When you realize it, call a professional to assess the damage’s extent, cost, and action to approach. 

  • Efflorescence

Efflorescence integrates the resettling of salt to a porous material’s surface.

That will often materialize in areas close to the openings since they permit water inside.

Despite not being as serious as mold, it’s still a sign of concern. 

  • Small cracks and gaps in the walls or floor surface.

Foundation wall cracks rarely disappear with time. Instead, they gradually worsen as time goes by. Fortunately, cracks won’t cost you much as other deformities. 

Mostly, large and gaping cracks result from poor foundation construction.

Therefore if you catch a glimpse of these signs, take action by applying a drylok paint. 

  • Bowed walls

The inward curves in your foundation wall need an instant fix-up.

If you fail to address this concern, long horizontal cracks will follow and probably compromise the whole structure.

For best results, you can fix bowed walls with steel bracing. 

  • Watermarks present on your wall’s surface. 

Whenever you see water stains running down your basement wall, know there is a leakage from the foundations’ top part.

It may transpire due to exterior infiltration and grading issues. If you fail to respond by applying drylok, the same will likely happen. 

Can You Use Drylok on Basement’s Interior? 

You are likely to ask if you are curious about dealing with musty or wet basements. Can you waterproof basement walls?

Yes, it’s possible. But to ensure you settle on the right option, find out whether moisture is developing from the outside or interior.

Once you have examined the source of moisture, you can prepare to seal the basement with drylok.

And as usual, adhering to the instructions is a sure way for reaping demanding results. 

Final Thoughts. 

It is now clear that painting over drylok is not a difficult task as you can imagine.

However, it greatly involves proper preparation of the surface to wipe out dirt and dust.

From there, you may want to fill the openings on the surface using a drylok fast plug. And finish by applying two coats of drylok. 

The most integral part of the entire process is to take your time to do the right thing. You don’t have to rush since you won’t get your desired outcome.

Also, remember not to overlook any step. If you jump any step, failure and myriad issues kick in.

So if you’re not strange or unfamiliar with the steps, call an expert to do it on your behalf. So…

Can You Paint Over Drylok

Yes, it’s possible. Painting over drylok is a matter of precise preparation and using the right tools. You may want to paint on a rain-free day for better outcomes.
