Barrier Urethane Surface Sealer
I’ve tried out practically every sealer out there, with mediocre to horrible results, Barrier urethane has become my go to sealer of choice. Barrier is gloss or matte finish, water based, low odor, urethane surface sealer that bonds really well to concrete. It can be used for indoor and outdoor applications and doesn’t break down from full sun exposure. Above all, it’s super easy to apply! You just roll it on using standard short nap paint roller. Two or three coats can be applied all in one day since it sets up quick and is fully cured in 72 hours… nice!
Here’s some more technical info about Barrier…
Barrier solves the common problems caused by applying a topical sealer to outdoor concrete surfaces. This chemical resistant sealer is designed to strongly bond to varied types of surfaces. For example, it creates a hard, abrasion resistant layer of protection over your concrete surface. Though extremely strong and highly UV resistant, Barrier’s true innovation lies in its ability to allow the transmission of water vapor. In other words, allowing the substrate to breathe! Now you can protect your outdoor surfaces from the harsh effects of weathering without causing spalling within the interior of the concrete. Likewise you won’t see delamination of the topical layer. Barrier is an excellent choice for indoor surfaces where strength and chemical resistance is required.
To sum it up, Concrete Chemistries’ Barrier is a highly durable, chemically resistant, surface sealer designed for use on exterior and interior concrete, stone, or masonry surfaces. Barrier’s UV resistant formula will not yellow or cloud over time and will strongly resist the harsh effects of outdoor weathering. Its water-based, gloss or matte finish only requires two or three coats in order to get extreme strength and beauty. However, it’s is also an excellent choice for indoor applications that endure significant wear. Above all you can use Barrier not only on concrete but on slate, saltillo, terra cotta,masonry, sandstone, tumbled marble, quartzite and other porous substrates where a semi-gloss finish is desired.
The videos below will help you with the application process. To clarify, each coat should be applied within one hour of each other for proper bonding. Apply multiple thin coats instead of one thick coat for best results. Keep back rolling the sealer until it’s completely clear before moving on to the next section.
