Use What the Professionals Use. DRYWAY PLUS is a highly concentrated, commercial-grade silane/siloxane blended water-repellent sealer. Designed and tested to meet or exceed the most rigorous ASTM and DOT performance standards. DRYWAY PLUS protects and preserves poured concrete, concrete blocks, brick and porous masonry surfaces from damage caused by ice melting chemicals, freeze/thaw, rebar corrosion and efflorescence. The advanced blend of modified silane and siloxane polymers and proprietary surfactants results in a deeper, longer lasting and more durable seal. DRYWAY PLUS imparts a non-yellowing, hydrophobic barrier below the surface, making it an ideal sealer for use on driveways, pool decks, sidewalks, patios, retaining walls, other porous stone structures. Stop wasting money on topical acrylic coatings that require reapplication every 1-2 years. Seal it with DRYWAY PLUS and forget it. Color: Flat/Clear.
