Frequently Asked Questions about DRYLOK®

 

Q. What advantages does DRYLOK® Masonry Waterproofer have over powdered waterproof coatings?

A. It’s much easier to apply because of its smooth, creamy consistency and one-step application saves considerable time. Using this product eliminates the need to pre-wet the surface or stock up on the extra pails needed when you mix by hand. Apply to dry or slightly damp surfaces.

 

Q. How can you tell if a surface is too wet to paint?

A. Rub your fingertips over the suspect area. If they are wet, do not paint the surface.

 

Q. How long will DRYLOK® Masonry Waterproofer maintain its effectiveness?

A. When applied according to directions, DRYLOK® Original Masonry Waterproofer is warranted for 10 years, DRYLOK® Extreme Masonry Waterproofer is warranted for 15 years, and DRYLOK® Floor & Wall Masonry Waterproofer is warranted for 7 years. In many instances, these products will provide many additional years of satisfactory performance.

 

Q. What is the coverage of DRYLOK® Masonry Waterproofer?

A. Both DRYLOK® Original Masonry Waterproofer and DRYLOK® Extreme Masonry Waterproofer cover 75-100 square feet per gallon, and DRYLOK® Floor & Wall Masonry Waterproofer covers 90-100 square feet per gallon, depending on the porosity of the surface.

 

Q. Can DRYLOK® Masonry Waterproofer be used on floors?

A. DRYLOK® Extreme and DRYLOK® Original Masonry Waterproofers are not formulated for floors. You can use DRYLOK® Floor & Wall Masonry Waterproofer on floors and walls. It holds up to foot traffic as a finished coat and can be used before applying floor paint, or latex-based adhesives.

 

Q. Can DRYLOK® Masonry Waterproofer be used over paint?

A. Yes and no. DRYLOK® may be used over any other cementitious-type waterproofing paint in good, repaintable condition, either inside or outside. However, DRYLOK® cannot be used over an oil or latex-based paint on the inside of a building. DRYLOK® will adhere to these paints, but if it cannot penetrate into the pores of the masonry itself, it will not waterproof the surface.

 

Q. Can DRYLOK® Masonry Waterproofer go over wood, metal or terra cotta?

A. DRYLOK® Masonry Waterproofer is not recommended for use on anything other than bare masonry and concrete surfaces. It can be applied to porous terra cotta, concrete, stucco, and cement.

 

Q. Can DRYLOK® Masonry Waterproofer be used as an outside foundation coating?

A. Yes, DRYLOK® Masonry waterproofer is ideal as a foundation waterproofing coating. Wait 24 hours after the application of the second coat to backfill.

 

Q. Can you paint over DRYLOK® Masonry Waterproofer?

A. Absolutely. In fact, DRYLOK® makes an ideal base coat. After applying DRYLOK®, wait at least 24 hours and then paint it with a good quality latex top coat.

 

Q. I’m press for time. Can I use DRYLOK® Masonry Waterproofer as an all-in-one primer and paint?

DRYLOK® Original Masonry Waterproofer’s sandy finish is available in 4 ready-mixed colors (blue, white, gray, and beige) and 6 tints (buttercup, mint green, platinum, sand, slate blue, and soft pink). If you prefer a smoother finish, choose DRYLOK® Extreme Masonry Waterproofer, available in bright white and an expanded tint palette (beige, blue, buttercup, gray, mint green, platinum, sand, slate blue, and soft pink).

 

Q. Can DRYLOK® Original Masonry Waterproofer be applied over Oil Base DRYLOK® Masonry Waterproofer?

A. Yes, wait 24 hours to apply.

 

Q. How do you recommend using DRYLOK® Fast Plug®?

A. Use on surfaces, cracks in walls, pools, wall joints and affixing objects that will be subjected to applied pressure.

 

Q. Which products help remove efflorescence and prevent it from reoccurring?

A. United Gilsonite Laboratories manufactures a product called DRYLOK® Etch. While DRYLOK® Etch will remove efflorescence and help prevent it from reoccurring, understand that efflorescence comes from salt deposits found in the block itself and can reoccur at any time.

A. DRYLOK® Concrete Protector has a curing compound and can be used on new concrete or old concrete to control dusting. It is a water sealer. DRYLOK® Floor & Wall Masonry Waterproofer stops water from coming up through the concrete floors. It is a waterproofer.

A. Use DRYLOK® Wetlook Sealer for a decorative high-gloss coat over floor paint.

 

Q. Can you put linoleum or tile over DRYLOK® Floor & Wall Masonry Waterproofer ?

A. Yes.

 

Q. Can I apply DRYLOK® to a fish pond?

A. DRYLOK® Original Masonry Waterproofer can be used to successfully waterproof fish ponds as long as the product is allowed to cure for the recommended 5-7 days. This cure time is necessary to ensure that all the volatile “processing aids” have completely evaporated from the dry film. Failure to allow for complete curing can cause excess foaming when water is added, and possibly even affect water quality.
