All previous coatings, except sound and firm cement base materials, must be removed. The surface should be clean, dry, and free from dirt and all loose particles. Cracks, holes, and loose mortar joints should be repaired using a suitable concrete patch or mortar mix. For best results, DRYLOKGrey Fern Grey Fern Grey Barbour Barbour Barbour Fern Barbour Fern Barbour Fern Barbour Barbour Barbour Grey Grey Grey Fern Fern Fern ® Water-Base 5% Silicone Brick and Masonry Sealer should be applied following a dry spell of 2 or 3 days. Remove dust, dirt, and any loose or broken mortar* with a wire brush. If you see white, powdery, crystal-like deposits on the surface, they are naturally-occurring, water-soluble salt compounds in the masonry, pushed out by water intrusion. When the water evaporates, the salt residue remains. This effect is called efflorescence and, because it prevents DRYLOK® Water-Base 5% Silicone Brick and Masonry Sealer from properly bonding to the surface, it must be removed. Treat it with DRYLOK® Etch** (liquid or powder formula) or muriatic acid according to the manufacturer's directions, rinse and allow to dry.
Barbour Grey Fern Grey Fern Fern Grey Barbour Fern Barbour Barbour Application
Schedule your project when both air and surface temperatures are 50°F or higher and, for best results, wait for a dry (rain-free) period. Do not thin the product. Protect glass, wood surfaces, and shrubbery from overspray. Spraying DRYLOK® Water-Base 5% Silicone Brick and Masonry Sealer is the most effective method of application. An ordinary garden sprayer or power equipment may be used. Best results are achieved by eliminating most of the pressure at the gun or nozzle and operating with the lowest practical pressure on the spray tank. The nozzle should be opened to a coarse spray adjustment. Starting at the top of the wall, hold the spray at an angle to avoid splashing. Flood the surface with DRYLOKBarbour Fern Barbour Grey Fern Grey Fern Fern Barbour Barbour Grey ® Water-Base 5% Silicone Brick and Masonry Sealer so that a run-down of 8 to 12 inches of material occurs. This permits an even flooding of the surface with a steady flow of material. It is important to hold the gun or nozzle close to the work.
If DRYLOK® Water-Base 5% Silicone is applied with a brush, extreme care must be taken to ensure even flooding of the surface. Do not brush it out.
