Talk about timing. I just went to a hardware store. And one of the clerk recommended this exact same product. My window type airconditioner is placed on the 2nd floor of our house. The water the comes out of the aircon is dripping right thru our cemented plant box which is also hanging at the side of our house. Problem is, underneath the plant box is the part ceiling of the first floor. Now it is damaged. Hopefully this application will do the trick
Your comment is well thought out, however remember that we are surrounded by the air which exerts 14.7 lbs. /square inch on us at all times.There is total pressure"absolute pressure" and "Pressure caused only by the water which is called, "gauge pressure."A cubic inch of water weighs 0.036 pounds so each foot of water weighs 0.432 pounds.Then at the bottom of a column of water which experiences 10 psi the height of the column would be: 10psi/0.4332 psi/foot = 23 foot column of water.
Engineers will recommend not sealing a wall with a nonbreathable coating because of structural damage. DRYLOK has a small permeable rating, which allows the coating to breathe and not trap moisture in the block. If the coating is applied properly and to a properly prepared surface, it will not peal and will holdup longer than the 10 year warranty.
i have a wet basement.... sometimes i get actual water, not just moisture. I was thinking of putting down this dry-lok stuff and then put down some foam puzzle mat flooring...... would the mat flooring be wize if my basement is wet?
@Yz85rider338 There are customers who have had success with DRYLOK on the floor as an undercoat to a carpet or matting. The DRYLOK Extreme would have less grit and probably hold up better to traffic. Again there would be no warranty for this application.
@unitedgilsonitelabs Where are you getting this 22ft high water = 10PSI? The pressure of the Earth's atmosphere is already 14.7PSI at sea level and increases significantly as you go underwater...by my calculations, the pressure at 22ft of water would be 24PSI...
I have had a few areas of seepage in my basement but not too bad. I want to chissel out the joint some (in areas) and apply a product but not sure what. I noticed you using the patch n plug in the video. Will that be good in the floor/wall joint or would you recommend something else? Also i want to stain my basement floor. if I coat the floor with drylock is it still possible to stain it? Thanks
@jwren49dream works best on bare masonry and warranty is only good on bare masonry. DRYLOK needs to enter the pores of the masonry and expand to become part of the wall. You can do your best to get the paint from the surfaces The best way to remove the old paint is anyway that will remove the most down to the bare surface. A grinder or sand blaster would work the best.
While I was close to going with sani-tred or something similar which claims to protect water with hydrostatic pressure up to 160psi...I did some research. Natural pressure on a structure 6 feet below grade (in water -NOT wet dirt) is about 3psi. I am pretty sure drylok is good for about twice that. Seems silly for me to spend 5 times what a gallon of drylok costs to overkill it.
DRYLOK is a waterproofer which is designed to hold back hydrostatic pressure (pressure exerted by a fluid at equilibrium due to the force of gravity). DRYLOK's proven waterproofing formula is specially designed to stop hydrostatic pressure while providing a minimal Perm rating to protect structural integrity. Water hits the warm interior and turns into vapor, vapor is able to escape the block never trapping water to cause structural damage.

I would like to try his but I have some concern as to where the water goes after you waterproof the wall. Don't the blocks just end up filling with water? And isn't that a bad thing?
Would it be recommendable to use drylok on exterior sub-grade block walls in addition to the interior walls or would using it on the interior suffice?
If you have an interior bare surface, interior walls would suffice. Many homeowners like to match their foundation walls to their siding color and tinting DRYLOK is a nice way to waterproof and give your house more curb appeal, but waterproofing the inside and outside is not necessary.
@unitedgilsonitelabs I would like to use drylok on the outside wall as an added precaution but there is a trace of what appears to be tar on it. I've used a pressure washer in an attempt to remove it but to no avail. I've yet only been able to partially remove it. Would this present a problem or could I apply the drylok over what is left of the tar?
The tar was applied to the exterior of your of your foundation as a waterproofer. DRYLOK would not be effective over the tar, it has already penetrated the pore of the masonry. You can apply in the inside walls however.
Hi - Moving into a house that someone improperly applied this before (must have tried on top of paint) and now it's all stripping and flaking off. How is the best way to prep the walls, i.e. remove the old paint and reapply a new coat? The video states a wire brush, but that may not be good enough to remove old paint. I was thinking a grinder? Also, there are waterproof cements out there. Would it be helpful to first apply a waterproof cement coat and then drylock on top of this?
The best way to remove the old paint is anyway that will remove the most down to the bare surface. The wire brush is to remove dirt and particles not paint. A grinder or sand blaster would work the best. If you had a bare surface, there would be not reason to use a waterproof cement. But over a previously painted surface this might be a better choice. You can remove as much paint as possible and apply DRYLOK, but the warranty is void, but should work as well as the existing paint holds up.
The best time to apply DRYLOK is when the wall is dry. If you rub your finger tips along the wall surface and they are glistening with water the surface is too wet to paint. Some dampness will not effect the application of the waterproofer. Too much water will affect the curing properties of the product.
This seems like what I need. I tried to build up the earth outside and slope it away from the house, but there is just too much water in the ground all the time. I am wondering if I can use the Dry Lock when the concrete blocks are still damp? I also have to find out how to check to see if my sump pump is working because I have not heard it lately, despite a lot of rain.
i really want to use drylok on our rooftop floor. but i also want tiles. is it ok that after i applied drylok paint on the floor, i will install tiles on top of it? i want to use drylok for double protection.
Understand that DRYLOK's warranty is only good for the products proper use which is on vertical surfaces. It is a softer coating so it does not formulated to hold up to foot traffic. However, you can use on the rooftop and tile over it or carpet over it because it is not be exposed to abrasion.
@zsarin the house I'm in has a damp to wet basement that was drylok painted on walls and floor some time ago. Then someone had the bright idea of gluing a rug to floor. Mold!
Paint is coming off now and water is still coming in as moisture and dampness and the concrete is spalling badly. I have to grind off the paint & glue to properly fix the spalling and repair cracks.
A trench drain at perimeter with a sump is the best fix (I'm going to install) for moisture & dehumidifier.
If you put a seal on your wall like drylock, what happens to that moisture that was trying to get in? Does it stay on the outside? Does it cause degradation from the outside?

Most waterproofing companies are saying not to seal cove joints between wall and floor. In my opinion, this method would be far less invasive (especially to an already finished basement) and less costly than installing a complete French drain system to try as a "first option." I plan to reroute the downspouts in solid pipe far from the home, and apply Quik Plug on the cove joints. Currently, it only leaks a tea towel's worth in a small area on major downpours. Wish me luck!
Excellent stuff. I have the same problem and my bricks are unpainted. My issue is that outside the wall there is about 2 feet of soil against it and when it rains the soil gets soaked and water seeps in through the brick joints. Will DRYLOCK stop this water as there will be some pressure from the outside?
Yes, DRYLOK will do the trick. Either apply on the inside or the outside. If you are going to apply to the outside, first remember that it is not a clear sealer so you will change the look of the brick and you must remove the 2 feet of soil, paint and than put the soil back in place.
Yes, it does have to be applied to bare concrete, the way DRYLOK works, it penetrates tiny pores in the surface and bonds itself to the masonry to act as an integral barrier to stop water seepage. The DRYLOK warranty will only be in affect for bare masonry, but if your paint is flat and in good condition, you can apply the DRYLOK over this paint and have sufficient waterproofing. As long as the flat paint (existing paint) maintains its adhesion, the waterproofer will waterproof.
Can Drylock work on bricks? We have bought a house that has drainage issues. I suspect we will need to have someone come in and dig a French Drain outside along the foundations of the basement. Meantime water appears to be seeping through the cavity brick wall and pooling on the concrete floor. The internal bricks are painted white. Can we use DRYLOCK on these bricks?
Yes, DRYLOK can be applied to bricks. Unfortunately, DRYLOK is best when applied to a bare surface. The waterproofer has to penetrate the masonry,expands as it dries to become part of the wall. You can try to paint over the painted brick; the warranty will be void because you are painting over an already painted surface, but if you prepare the surface and make sure there is no loose, you should have waterproofing success.
A high pressure water blasting, sanding blasting and lastly paint and varnish remover. The paint and varnish remover would be for a small area because of the vapors. The DRYLOK warranty will only be in affect for bare masonry, but if your paint is flat and in good condition, you can apply the DRYLOK over this paint and have sufficient waterproofing. As long as the flat paint (existing paint) maintains its adhesion, the waterproofer will waterproof.
Awesome video! Just the info I was looking for? My house is on a zero lot line ....row house. I have groundwater leaking into the walls. Does the wall have to be totally dry to apply drylock? How do I dry the walls to apply the paint if they're always wet?

When using DRYLOCK Etch the directions say to rinse thoroughly after applying. Do I need to put a hose on it or just something like a spray bottle? I would like to use a shop vac for cleanup. Will the runoff be harmful to a shop vac? I`m just not sure how powerful DRYLOCK Etch is. Thanks
The spray bottle is fine, all you are looking to do is to rinse away the desolved salt (efflorescence). After it has reacted with the salt, the acidity is lower and will not effect the shop vac.
Thanks so much. UGL makes a DRYLOK Concrete Latex Paint that has a flat finish, but can be top coated with a wetlook sealer. There are epoxy paints that will give you a high gloss finish, but any epoxy paint is very susceptible to peeling if there is any moisture coming through the floor. You can also seal bare concrete with DRYLOK WetLook Sealer without painting it first. We do not recommend DRYLOK Masonry Waterproofer on floors, It is not formulated to withstand foot traffic.
Although I can not waterproof your basement, it is an easy do-it-yourself project that is as easy as painting a wall. Take the plunge and try it yourself, you will be surprised at how easy it is and the results are great.
A high pressure water blasting, sanding blasting and lastly paint and varnish remover. The paint and varnish remover would be for a small area because of the vapors. The DRYLOK warranty will only be in affect for bare masonry, but if your paint is flat and in good condition, you can apply the DRYLOK over this paint and have sufficient waterproofing. As long as the flat paint (existing paint) maintains its adhesion, the waterproofer will waterproof.
Unfortunately, DRYLOK is best when applied to a bare surface. The waterproofer has to penetrate the masonry, it expands as it dries to become part of the wall. You can try scraping the loose paint, suring up the surface with DRYLOK Concrete Protector and than painting DRYLOK Masonry Waterproofer over the substrate. The warranty will be void because you are painting over an already painted surface, but if you get all the loose paint off, you should have success.
As long as the mortar is in sound condition and there is no previous coating on the brick, DRYLOK is the ideal choice. Any loose or crumbling must be repaired with a patching compound, this will be an area where water will want to enter.
DRYLOK Masonry Waterproofer has to penetrate the pores of the masonry. It actually expands as it dries and becomes part of the masonry. The warranty on this product only works when applied to bare masonry. You can however scrape paint and apply over it, if you get any release of the old paint, you can reapply the waterproofer in those areas. Again, the warranty would be void.
In our research, we have found that brushing works the best to push the product into the pores of the masonry, however you can roll or spray and back brush any areas you see has not gotten the proper coverage.

You can try scraping the loose paint, suring up the surface with DRYLOK Concrete Protector and than painting DRYLOK Masonry Waterproofer over the substrate. The warranty will be void because you are painting over an already painted surface, but if you get all the loose paint off, you should have success.

I have an old home with a brick foundation and a concrete floor. Will drylock work on brick?

As long as the mortar is in sound condition and there is no previous coating on the brick, DRYLOK is the ideal choice. Any loose or crumbling must be repaired with a patching compound, this will be an area where water will want to enter.

Should Drylok be used on the floor too?

DRYLOK is not formulated to withstand foot traffic, so we do not recommend it for floors.

I have the identical problem only my wall has been painted. What should I do apply over the old paint? or remove the old paint?

DRYLOK Masonry Waterproofer has to penetrate the pores of the masonry. It actually expands as it dries and becomes part of the masonry. The warranty on this product only works when applied to bare masonry. You can however scrape paint and apply over it, if you get any release of the old paint, you can reapply the waterproofer in those areas. Again, the warranty would be void.

Do you recommend spraying Drylok extreme on the walls when possible and should I go over it with a roller or brush?

In our research, we have found that brushing works the best to push the product into the pores of the masonry, however you can roll or spray and back brush any areas you see has not gotten the proper coverage.
