Sometimes this is a question of what type of counters does Refinish First refinish, while other times it is a question of identifying the existing material.
To answer the first question, Refinish First refinishes laminate, Formica, ceramic tile, Corian, Silestone and cultured marbled surfaces (fiberglass too but this is more of a tub thing and less of a counter thing).
Ceramic tile is easy to identify because of the grout lines and the fact that it is all over the place. However, other materials can blur together because the names are interchangeable, misnamed or often the counter has been around for 10,000 years and the material name is long forgotten. Not to worry.
The first step is to contact Refinish First to come out and determine if your counter is a viable option, answer any other refinishing questions and provide an estimate. It is hard to make a plan if you aren’t sure where to start. Find out so you can move to step two.
