Product Description

Ultra SI is the most ground-breaking concrete sealer in this age of low VOC coatings. For decades, water based concrete sealers have been considered the second rate to solvent based sealers despite slight improvements that have been made to them in terms of durability and gloss. The biggest drawbacks were, and, continue to be recoatability and the ability to enhance(wet out) the concrete surface like their solvent-based counterparts. Even the most common solvent based acrylics will darken the surface nicely and can be recoated every couple of years with minimal preparation and fuss. Solvent based sealers have come under fire the last few years due to their high VOC limits. Most states have enacted strict VOC limits of these products which have resulted in sealer manufacturers being forced to use special solvents that meet these requirements. These newer solvents make sealers much less user-friendly and result in many more issues with the sealed surfaces in terms of blistering and improper cure. Even though water based sealers do not share these problems with solvent-based sealers, they continue to be chosen last for the previous issues mentioned. Color enhancement and recoatibilty.

Ultra SI is the first waterborne decorative sealer that will actually enhance and wet out the surface like that of its fully solvent based counterparts! In fact, Ultra SI will provide all the great characteristics that you are used to with your regular solvent-based sealer without the less desirable traits. It may very well be the best decorative concrete sealer ever produced in terms of coverage, durability, and ease of use.
