Clean the laminate thoroughly to remove all dust, dirt, grease and debris on the surface. Allow the countertop to dry completely before continuing.
Tape off the edges of the counter where it meets the wall and around the sink with painter's tape. Press down firmly on the edge of the tape where it meets the counter to avoid having the paint bleed up under the tape.
Pour some of the black, primer coat from the kit into a paint tray. Use the included roller to apply the primer to the countertop. Cover the surface with overlapping strokes to avoid lines. Let the primer coat dry until it's no longer tacky.
Pour out the three mineral paints in the kit onto paper plates. Practice dabbing the sponges, included in the kit, into the paints then onto the test paper, also part of the kit. Layer the paints from dark to light, using the lightest color sparingly as highlights until you get the look you want and are comfortable working with the paints. If you are adding acrylic colors, sponge them on in the same way.
Sponge a layer of the darkest mineral paint onto the countertop. Tap the sponge gently onto the counter in a random pattern until the surface is covered.
Sponge the medium color on next, moving in a random pattern over the darker color. Add the acrylic colors at this time if applicable.
Apply the highlight color sparingly to complete your granite look. Allow the paint to dry.
Roll the first coat of topcoat onto the counter to seal the paint. The topcoat may appear milky in color to help you see where it is being applied; it will dry clear. If you're applying multiple layers of topcoat, allow at least four hours between each coat. Do not set anything on the finished counter for at least 72 hours. The paint will fully cure within two to three weeks.
