Use this product if you do not want to the change the look or feel of the countertop but need protection from water and light spills. Since it is a solvent carried product it will outperform the 770.
The Countertop Sealer 880 is a solvent-carried food safe (once cured) sealer that will not change the look or appearance of the concrete countertop whatsoever. The 880 leaves a similar finish to the 770; however, its high actives content, ease of application, deeper penetration and longer lifespan set it apart. The 880 is able to resist light staining from household substances causing fluids to sit on top of the concrete rather than penetrating into the concrete giving you a few extra minutes time to wipe up the spill. The Countertop Sealer 880 is easy to apply and is ready to use right out of the container - no mixing is required. Two coats wet-on-wet (immediately apply a second coat while the first coat is still wet) are recommended. Use in conjunction with a countertop wax for an extra layer or protection.
The longest lasting and best performing countertop sealer we offer. This high gloss, wet look formula is able to withstand food stains, spills, chemicals and abrasions.
The Polyaspartic 745 is typically used in commercial kitchens and bars since it is the most durable countertop sealer available. The Polyaspartic 745 can also be used on warehouse floors and is able to stand up to forklift traffic, chemicals and abrasions so using it on a concrete countertop is a no brainer. The 745 can only be used on interior concrete countertops and leaves the surface with a high gloss finish. Since it is a coating rather than a sealer it sits on top of the concrete providing a smooth surface environment that allows for easy clean up and completely stops anything from penetrating through it. Before applying the 745 we recommend sanding the concrete countertop with a 220 grit pad to ensure the surface has enough porosity for the coating to adhere to. The Polyaspartic 745 is sold in a 2 part kit, so you need to mix Part A with Part B. It has a short workable life, which means once you mix Part A with Part B you have about 15 minutes to apply it before it begins to harden and is unworkable. You do need to let the countertop dry for at least a full 24 hours before use. Once cured you are left with an extremely durable, high gloss concrete countertop.
If you are looking for a little bit of shine that is not overly glossy but still able provide protection from light spills, use this product
If you are looking for a low sheen finish on your concrete countertops that is not as glossy as the 745 but not as flat as the 770 and 880, the 660 is an excellent option. Especially since is completely non-toxic, water-based and safe for interaction with food once cured. The Countertop Sealer 660 is easy to apply; simply mix the concentrated solution with equal parts water and spread the solution over the countertop with a rag for five minutes. Continuously make sure the countertop is wet for the whole five minutes, then let the sealer completely penetrate into the concrete without wiping it up. After the surface has dried, apply another coat at a 3:1 ratio of sealer to water, which will help fully protect your countertops. Use in conjunction with a countertop wax for an extra layer or protection.
