What is the best sealer for decorative concrete?
The best concrete sealer for decorative surfaces are acrylic based sealers. Acrylic concrete sealers are either solvent based or water based. Solvent based acrylic sealers usually are better sealers than water based acrylics since they leave a high gloss shine and wear stronger and longer. Water based acrylics are recommended if you do not want a strong solvent odor or if you need a sealer with low VOCs, or live in a state like California. Solvent-based acrylics are best for exterior applications and water based acrylic sealers are best for interior applications. The best acrylic sealers are UV resistant and non-yellowing. Beware of high gloss solvent-based acrylic sealers that can become slippery when wet. Some manufacturers will offer customers non-slip additives to prevent slippery surfaces. Acrylic concrete sealers are the best sealers to use on decorative concrete to protect the surface and enhance the color. They are fast drying sealers usually drying within an hour.
You can apply Cryli-Tek 5505, a solvent based sealer to leave a decorative glossy finish and to add extra protection again water and chloride intrusion, or you can apply Cryli-Tek 5500 a water based sealer, to leave a matte finish to leave a subtle satin sheet and to protect against water. If you are looking for the longest lasting sealer that does not have to reapplied for up to ten years it is best to use a penetrating sealer such as the Siloxa-Tek 8500. Although it will not change the look or appearance of the concrete, it will protect the concrete from water, salts and organic growth.
