DryWay Concrete Sealer Instructions

By RadonSeal | March, 14th 2020


Product Information

DryWay Water-Repellent Concrete and Masonry Sealer is a water-based blend of chemically reactive siloxanes and silanes, specially formulated for deep penetration and long-lasting protection. DryWay penetrates deep into the substrate to chemically bond and form a water-repellent barrier deep below the surface. DryWay protects concrete driveways, bricks, pavers, and other porous masonry from deterioration, staining, cracking, spalling, freeze/thaw cycles, moss and algae growth.

USES

Outdoor concrete, concrete blocks, cinder blocks, limestone, sandstone, split-face blocks, terra-cotta, brick, mortar, and pavers.

Coverage

  • Indoor Poured Concrete: 200-250 sq. ft. per gallon.
  • Outdoor Poured Concrete: 150-200 sq. ft. per gallon.
  • Concrete Blocks: 80-120 sq. ft. per gallon.
  • Bricks & Pavers 120-150 sq. ft. per gallon.

SURFACE CONDITIONS

Concrete should be DRY prior to application. Concrete may require several days to dry after heavy rain or pressure washing. Avoid rain for 12 hours after sealer application. Ambient air and surface temperatures must be above 40º F during the application and for 72 hours after. Avoid applying in excessive heat (over 90º F) and to hot surfaces in direct sunlight, or in strong winds and excessive humidity. New concrete should be allowed to cure for at least 28 days.

SURFACE PREP

Surfaces must be clean, bare and porous. Vacuum or blow off excessive dust and loose particles. Repair cracks and joints prior to application. Mask surfaces not intended to be sealed. Remove paints, sealers, curing compounds, adhesives, oil, grease, mold, efflorescence and other contaminants that might interfere with the penetration of the sealer. If acid is used, it must be completely neutralized before applying. The surface must be porous enough to readily absorb the sealer. Hard-troweled concrete surfaces require chemical etching or mechanical abrasion to increase porosity. Use PowerEtch Concrete Etcher & Cleaner to obtain a proper surface profile. If chemical cleaners or concrete etchers are used, be sure to throughly rinse and remove them prior to sealer application.

TESTING

Recommended! Concretes vary greatly in composition, finishing techniques and surface porosity. Apply DryWay™ to a small test area to confirm surface suitability, aesthetics, and ensure sealer penetration.

APPLICATIOIN

Apply using a hand-pump sprayer equipped with fan tip nozzle (recommended). Alternatively, a paint roller can be used only when spraying is not feasible.

STEP 1: Agitate container thoroughly before use.

STEP 2: Spray DryWay uniformly to the surface, maintaining a sufficient continuous wetting film. For vertical surfaces, apply from bottom up allowing 4-6” rundown.

STEP 3: More porous surfaces may require two applications. While the concrete is still damp, apply a second wet-on-wet application to the surface about 10 minutes after the first application.

DO NOT OVERAPPLY. Avoid pooling or excessive rundown. Broom, roll, or brush away puddles until the sealer has fully penetrated.

CLEAN UP

Rinse tools with water and liquid detergent immediately after use. Remove overspray with a wet towel before it dries. Dispose of unused material and empty containers in accordance with local regulations.

DRYING & CURING

Treated surfaces will begin to appear dry in 3-6 hours. Avoid foot and vehicular traffic until dry. Water repellency will develop over a period of 4+ days after application.

STORAGE

Store in a dry location out of direct sunlight. Do not store at temperatures above 100 °F. Avoid freezing. SHELF LIFE: 1 year from date of shipment. FINISHED APPEARANCE: Natural Look.
