ENVIROSEAL® 40

How to Apply Enviroseal® 40
Surface Preparation
Verify substrate has properly cured. Concrete should
obtain 80% of design strength, typically achieved within
14 to 28 days.
Concrete surfaces shall be cleaned of all sand, surface
dust and dirt, oil, grease, chemical films and coatings and
other contaminants prior to application. A complete
waterblast, sandblast or shotblast may be needed to
achieve the desired surface condition.
Surface, air, and material temperatures should be 40°F
to 110°F (4°C to 43°C) during application. Do not apply
Enviroseal® 40 when temperatures are expected to fall
below 40°F (4°C) within 12 hours.
Surfaces to be treated can be slightly damp; however,
a dry surface is suggested for maximum penetration of
sealer. Enviroseal® 40 should not be applied if standing
water is visible on the surface to be treated.
Crack control, caulking, patching and expansion joint
sealants can be installed prior to or following application
of the sealer. Allow a minimum of 6 - 12 hours curing
time for caulking and sealant materials (or until they have
skinned over) before applying Enviroseal® 40.
Application
Test small area of surface (generally a 5' x 5' [1.5 m x 1.5 m]
section) before starting general application of any clear,
penetrating sealers to ensure desired results and coverage
rates. Allow 5 - 7 days for the product to fully react before
evaluating. Refer to Tech Note: Test Area Application.
Stir material thoroughly prior to and during application.
Apply to saturation. This may be done by low-pressure
non-atomizing spray or pouring, followed by a squeegee
or a broom for even distribution.
