Q:Can this product be applied over an existing painted concrete wall?

Answer This Question

A:  Charlie, yes but if the existing coating is not DRYLOK® or a similar waterproofer, it may not work as intended as a hydrostatic water pressure resistant waterproofer, it will simple be a decorative coating with mildew protection. If you need to establish a true waterproofer finish, the previous coating must be removed.

    Amazing outdoor waterproof
    Thank you drylok for saving my house foundation I pressure washed the whole outside foundation after a wire brushed and etched the whole house around took everything loose out after that walls waiting like a hour for the walls to dry and protect the whole floor after one coat the house looks fresh and clean and waiting another 2 hours to do the second coat what beautiful performance and that same day we had rain and thunderstorms but I was so surprised nothing was sticking to the walls thank you

      Slapped on one heavy coat and it looks great! Worth getting the extreme for a couple extra bucks.

      Delivered as 1 gallon block of rubber
      Received two 1 gallon pails, completely rubberized, as if the lid had been off for a year.

      JayK - Sorry to read this. Could you please give us a call at 1-800-845-5227 unless you already contacted homedepot.com. It's very possible the carrier mis-handled the shipment causing the lid to pop and allow the paint to skin over. wtuckerugl

        Painting basement walls
        I bought this to paint our basement walls. It looks great now. It changed the looks of my basement. I feel like it made the room feel bright and not like an old dungeon. It helped make it a dry place. Before we had some water seeping through a spot or two and now it's dry.

          Nothing short of incredible.
          I have applied 30 gallons of this product on my basement floors, garage floor, driveway, and concrete block buildings (1300 square feet of buildings). It exceeds my expectations better than any product that I have ever used. I had a handyman business for 21 years in a high income area.

              Robin, Sorry to see this review. Applying two coats is good, but applying at 100 square feet per gallon is required. Unfortunately, we have seen jobs where the product was applied at a much higher square footage rate that leads to failure. Check our coverage calculator at this link: https://www.drylok.com/drylok-coverage-area-calculator Would you please give us a call to discuss your project? You can reach us at 1-800-845-5227. We would appreciate the opportunity to address your concerns. wtuckerugl

                Excellent adhesion & appearance!
                Currently renovating a 1970's home/garage that has been neglected. I chose gray for the garage footer blocks. I repaired the cracks/holes in the blocks with Quikrete hydraulic cement, trimmed the excess batt insulation between the sill board and blocks, then caulked the joint between the sill and blocks with Dynaflex 230. After all was dry, I gave it a heavy coat of Drylok Extreme on the wood sill plate, caulk, and blocks. Drylok adhered to all & looks great. Highly recommended!

                  Best paint
                  I only want to paint the basement cinder block walls ONE time - so I used the best paint I could find, Drylok Extreme. I now have bright white walls that reflect more than the little bit of lightbulb light in the dim basement. Tips: use a cheap stiff bristle brush and push the paint into all the holes and crevasses, the cinder blocks soak up a lot of paint so keep at it, paint on a second coat, put the paintbrush into a plastic baggie in between interruptions, use a slim fluffy roller to get behind the hot water tank as best you can, keep a fan blowing because it does get a bit smelly.

                    Basement level garage remodel
                    I used the drylok extreme masonary paint in white to paint my basement entry garage. It fully solved the moisture issues I was having on the parts that are underground. I applied two coats in my single car garage and used about 5 gallons.
