A number of products on the market are designed specifically to paint your countertops. Some countertop paint is sold in a kit that includes everything you will need to transform your kitchen or bath surfaces. The kits are designed to help you imitate the look of granite or marble with a few simple coats of paint. Getting this technique to look good and last for years involves careful preparation and the right painting techniques.
Choose a countertop paint that you like. Most countertop paints come in a kit with three to four paint colours. You will mix these colours to create a look similar to granite or marble.
Spray your counters with ammonia-based cleaner. Scrub the counters to remove grease and residue. Dry the counter thoroughly.
Attach medium-grit sandpaper to a palm sander. Move the sander across the entire surface of the counter to create texture. Some texture will allow the primer to sink in and adhere to the surface. Remove the sanding dust with a damp rag.
Apply primer in the corners of the counter with a trim brush. Follow with a smooth roam roller and roll a thin, even coat of primer onto the counters. Allow the primer to dry for eight hours.
Apply the base coat of paint to the countertop surface. The base coat will be the most visible and prominent colour of the counter. Apply the paint in the same way you applied the primer. Allow the first coat to dry to the touch. Add a second coat of the same colour. Let the paint dry for four to six hours.
Pour an accent colour onto a paper plate. Dip a sea sponge into the paint and dab the colour onto the counter. Start with a small amount of paint. Step back to evaluate the effects of the paint job. Add more paint if necessary. Let paint dry for 30 minutes.
Repeat this process with the other accent colours. Continue to layer the paint, imitating granite or marble. Allow the paint to dry overnight.
Roll on a urethane topcoat over the countertop paint with a smooth foam roller. Apply one to two coats of topcoat. Let the paint cure for seven days before using.
There are many different brands of countertop paint. Refer to your product's instructions before proceeding with the paint job.
