Thoroseal®

Thoroseal® is a cement-based, micro-porous (breating), seamless coating use to fill, seal, waterproof and protect a variety of substrate including cast-in-place and pre-cast concrete, brick, common building and split-faced block, stucco, unglazed terra cotta, porous stone, shotcrete, gunite, and other masonry substrate. It may be used on interior or exterior, above or below grade applications on new construction or renovation and restoration projects. Thoroseal® is highly resistant to standing water or wind driven rain and is intended for use on vertical, overhead and non-traffic bearing horizontal surfaces.

Thoroseal® is also ideal alternative to mechanical finishing or rubbing of concrete. The two coat application of Thoroseal® will add a significant degree of protection from the deletrious effects of carbonation of steel reinforced concrete. Two coats of Thoroseal® (40mils) is the equivalent to 3/4" of new concrete cover as a barrier to carbon dioxide gas. Thoroseal® has also been shown to act as a barrier to the infiltration of radon gas and can be used on below ground structures as a barrier coating in conjuction with radon abatement system. 

Clean and prepare surface:

1. All surfaces to be coated must be clean and structurally sound.
2. Chip, sand or shotblast, wet blast or high pressure water wash (4,000-10,000 psi) to remove all foreign matter, dust, dirt, paint, oil, grease, coatings, laitance or any other surface contaminants.
3. All static cracks or breaks, voids or honeycombing larger than 1/32" should be cut out and repaired. 

Mixing:

• Thoroseal® powder may be mixed by hand or by using a power mixer fitted with a mixing paddle. Power mixing is always preferrable. 
• Mix Thoroseal® powder using a solution consisting of ACRYL 60 diluted with water, usually 1 part of ACRYL 60 to three parts of water.
• For improved curing, better physical properties and improved bonding capability in extreme environments or on dense or questionable surfaces, reduce the dilution ratio to 1:2 or 1:1.
• A 50lb (22.7kg) bag of Thoroseal® requires approximately 6-8 quarts of mixing liquid. 
• Mix the material until a consistency of smooth, heavy batter is achieved. 
• Allow the mixed Thoroseal® to rest undisturbed for a minimum of 10 minutes to fully wet out all the powder. Remix the wet material and then apply to the substrate.
• When remixing, a small amount of mixing solution may be added for better workability.
