Test Color, Crushed Glass and Sealer Gloss Before Buying
Pouring a concrete countertop sample to test for color, aggregate placement and sealer gloss is best way to get the final result you’re hoping for. Direct Colors offers integral color, crushed glass and granite sample kits to create any variety of color/aggregate combinations. We also offer sample size and mini kit countertop sealer options.
Starting with a concrete countertop sample allows you to practice technique and make mistakes on something other than your actual project. Begin with a 3lb. concrete countertop mix sample along with a color pack to create any sample on our gray or white-based concrete pigment color chart. We’ve added brown and blue fine crushed glass aggregate to our mix but any size glass or crushed granite aggregate will do. Mix using a birdcage mixing paddle, pour into your form and trowel into place. We are mixing approximately 7.5 lbs. of finely crushed glass per 50 lbs. of DCI concrete countertop mix.

Choosing a countertop sealer can be tricky and three important factors should be kept in mind while making a decision. First, expected gloss level is key and Direct Colors offers everything from a Matte to a High Gloss. Our 550 Water Based and 500 Solvent Based Polyurethanes are featured in the picture below. Test samples help determine how much or how little gloss you prefer. Second, if you are sealing a countertop indoors, odor could be a problem. Solvent based sealers have a very strong odor and may not be appropriate for occupied homes. Go with a water based product if you have pets or small children. Lastly, whether the countertop is indoors or out is critical. For example, epoxies cannot be used outside. Polyurethanes are your best bet for outdoor and indoor kitchens.
Sample size products are also perfect for concrete decor projects like stepping stones or pavers and make great art projects for students. Concrete countertop samples could be used be used for pavers and similar purposes once the testing is complete. Get creative!
