Why Contractors Choose It
Contractors choose SpecSilane 20 WB when the slab or surface needs protection, appearance control, and a sealer matched to exposure conditions.
SpecSilane 20 WB is used to protect concrete and masonry surfaces such as decks, pavements, parking structures, ramps, bridges, and marine platforms against corrosive effects from de-icing salts, moisture, and weathering to prevent spalling and deterioration.
New Concrete
Surfaces should be well cured (minimum 28 days).
Ensure the surface is free from curing residue, dust, debris, oil, and other contaminants.
The concrete must be absorptive to allow proper penetration of the sealer.
Old Concrete and Masonry
Remove any previously applied sealers and surface contaminants with pressure washing andSpecChem Citrus Cleaner.
Verify the substrate is absorptive for effective sealer penetration.
