Pot life for the overlay is approximately 45 minutes and can be extended by 15 minutes by using ice cold rather than room temperature water.If using colored concrete pigment, water should be kept uniform for every box of overlay to avoid color discrepancies.To thin the overlay during application, add water as needed up to a maximum of one additional gallon.For a thicker consistency, use less water.Thoroughly combine the water and overlay to insure the dry polymer is saturated and properly dispersed.For best results, use a birdcage, high-shear paddle for bucket mixing.box of overlay into the bucket while mixing continuously with a drill mixer Pour one gallon of water into a five gallon pail first.A good polymer creates superior strength, adhesiveness, flexibility and is extremely weatherable. Any non-structural cracks wider than the hairline should also be repaired.īarefoot Concrete recommends using a flexible concrete polymer that maximises the prevention or the reoccurrence of cracks. Proper surface preparation of the concrete is also imperative to ensure good bonding of the overlay. The concrete must be structurally sound, without gapping cracks, severe delamination, or an unstable subbase. Not all existing concrete is a suitable candidate for a polymer-modified concrete overlay.
