DRYLOK MASONRY LATEX WATERPROOFER - Wall / Basement seepage
If you have a problem with water leaking through bare masonry walls in and around your home use a paint that stops water–DRYLOK. DRYLOK Masonry Waterproofer is specifically formulated to waterproof interior or exterior, above or below grade masonry surfaces. DRYLOK works by penetrating tiny pores in the masonry, it expands as it dries to form a tough waterproof barrier. DRYLOK Ready-Mixed Masonry Waterproofers are formulated to withstand hydrostatic pressure of 10 psi which is equivalent to water pressure at a depth of 22 feet (1,440 pounds per square foot). DRYLOK Masonry Waterproofer is America’s most versatile masonry waterproofing paint.

What Is Causing The Water Seepage?

Whenever you discover wetness on interior masonry walls,
find out what is causing the seepage problem.
Check for leaky gutters and downspouts, blocked drainage pipes,
improper grading or ruts that direct water towards your foundation.
For best waterproofing results, correct all of these problems before applying DRYLOK Masonry Waterproofer.

Is It Seepage Or Condensation?

Make this simple test:
Tape a 12" x 12" piece of aluminum foil tightly on all four edges to an interior basement wall.
Remove it after several days. If the wall side of the foil is wet, you have seepage and need to apply DRYLOK.
If the room side is wet, it's condensation. Remember, both problems can occur at the same time.
For condensation, use a dehumidifier.

How DRYLOK®Works.
DRYLOK Masonry Waterproofer penetrates tiny pores in the surface and bonds itself to the masonry to act as an integral barrier to stop water seepage. Ordinary paint only adheres to the surface and oncoming water pressure can force it off.

Prepare The Surface.

May be applied on slightly damp surfaces, but best results are obtained when applied over dry surfaces. For best waterproofing results, wait for a dry (rain-free) period. Surface must be clean and free from dirt, dust, grease, oil, form release compound or paint. DRYLOK is not warranted when used over previously painted surfaces or on horizontal surfaces. DRYLOK may be applied over surface previously painted with Latex Base DRYLOK Masonry Waterproofer.

As with any painting project, surface preparation is the most important step. Before applying DRYLOK® Masonry Waterproofer, clean the surface thoroughly with a wire brush to remove all loose and broken mortar, dirt, dust, efflorescence (salt-deposits) from all surfaces to be painted. Old paint must be removed by wire-brushing, sand-blasting or by using other suitable means. DRYLOK® Masonry

The worst enemy to any masonry waterproofing paint is efflorescence. This white, powdery deposit is formed when naturally occurring water-soluble salt compounds, that are present in the masonry, are drawn to the surface by water seepage. These deposits prevent the masonry waterproofing paint from adhering to the surface of the wall.

Seal The Floor And Wall Joint.

An area that is often overlooked as a source of water seepage is the floor/wall joint. Normally, when concrete floors cure, they shrink and pull away from the wall, allowing a space for water to enter. Clean the area and wet down with water prior to patching. Fill all gaps between floor and walls with DRYLOK Fast Plug. Seal The Floor And Wall Joint. An area that is often overlooked as a source of water seepage is the floor/wall joint.

Apply DRYLOK To Basement Walls.

Stir thoroughly before and during application. DRYLOK should be applied to clean, bare masonry. Apply DRYLOK Masonry Waterproofer when the air and surface temperatures are above 50°F. For best results wait for a rain free period. Apply the first coat with a stiff bristle brush working the DRYLOK thoroughly into the pores of the masonry. After using the first gallon of DRYLOK measure the area covered. It should be about 75 to 100 square feet. This thick bodied masonry paint is formulated to provide a waterproof barrier and is not intended to be spread thin like regular wall paint. Two coats are required to assure warranted waterproofing. Allow the DRYLOK to dry according to manufacturer’s directions between coats.The second coat can be applied by brush or masonry roller.
