Before you begin overlaying a formica countertop, ensure the existing countertop is well reinforced and exhibits no flex.

Scuff the surface with a 120 grit non-loading sandpaper.

Thoroughly clean all dust and debris from the surface in preparation for the concrete overlay.

Pour the contents of one fifty pound box of Overlay in a five gallon pail.

Slowly pour one gallon of water into the five gallon pail.

Average working time of Overlay is up to 20 minutes.

Add ice water to extend working time of overlay for up to an additional 10 minutes.

Dry, hot weather conditions reduce working time.

Mix continuously with a drill mixer.

For best results, use a birdcage, high-shear paddle for bucket mixing.

Thoroughly combine the water and overlay to insure the dry polymer is saturated and properly dispersed.

Overlay the vertical surfaces before the countertop face.

To trowel overlay on to vertical surface, the overlay consistency needs to be thick enough to stick to the vertical surface.

Once the vertical application is complete, mix the remaining overlay to a thin pancake batter consistency and pour it onto the surface.

For a 1/16th to 1/8th inch skim coat, apply the overlay with either a pool trowel or a magic trowel.

The magic trowel will allow a less-experienced person to achieve a more uniformly smooth surface.

Overlay the surface and allow to dry for 3-6 hours or until the overlay achieves a uniformly light gray color.

Use an 80 grit non-loading sandpaper to grind down rough edges and smooth out the surface.
