TOTALSEAL UHS ® is a two-part epoxy coating system that has been designed with specific additives to promote adhesion when used on concrete and masonry. It is high in solids to be used for low V.O.C. and “green” applications. TOTALSEAL UHS ® demonstrates excellent chemical and solvent, fire and static resistance. It will provide outstanding water and humidity resistance as well.


Surface must be clean from oil, tar, rust, grease, salts, and films.
  1. Use general degreaser if needed.
  2. Clean surface using TSP (tri-sodium-phosphate) or a citrus cleaner to release dirt and degreaser residue.
  3. Pressure-wash if possible @ 3500 psi.
  4. Salt contamination on a surface can come as a result of salt water, fertilizers, and car exhaust. Use Chlor*Rid or equivalent to decontaminate surface if salts are present. Acceptable levels: Nitrates: 5-10 mcg/cm², Sulfates: 5-10 mcg/cm², Chlorides: 3-5 mcg/cm²

Surface must be completely dry before applying.

  1. TOTALSEAL UHS ® must be applied during proper temperatures (below) and the prescribed overcoat window of the coating over which it will be applied.
  2. If applied over an existing coating having a glossed or shiny finish, it must be sanded and roughed to remove gloss before application, to improve the profile.
  3. Additional coats of TOTALSEAL UHS ® can only be applied when the 1st coat becomes tacky to the touch and has little to no transfer of coating. After this stage, the surface must be lightly sanded to improve the profile.
  1. Open pail, mix base with curing agent (1 part base : 2 part curing agent) (ratio by volume, not by weight)
  2. Mix by hand for two minutes, or using drill and Mixing blade for a minimum of 30 seconds with NO vortex.
  1. Apply between 40°F (4°C) and 100°F (38°C).
  2. Maximum temperature for continuous use when cured is 300°F (149°C).
  3. Store unmixed product between 40°F (4°C) and 100°F(38°C) according to hazmat standards on MSDS.
  4. Mix base and curing agent and use immediately if ambient temperature is above 60F (16C). If below 60°F (16°C), allow mixed product to stand for 30 minutes before using @ 70°F (21°C).

4-6 hours at 70°F (21°C) - 1 hour at 90°F (32°C)

TOTALSEAL UHS ® can be applied by brush, roller or spray; however, the preferred method is by air or airless sprayer.
  1. If application is by brush, use a soft bristle brush.
  2. If application is by roller, use a 1/2 inch nap roller.
  3. If application is by spray, use a heavy duty airless sprayer (2 gallons/minute at 3,300 psi.) with a .029- .033 tip.
NOTE: The number of applications and the thickness of each should be in accordance with the job specifications.
NOTE: Temperatures must always be a minimum of 5 degrees above the dew point during application.
MINIMUM SPREAD RATES (mil thickness)

Porous Surfaces– Apply 1st application using a 50/50 mixture of TOTALSEAL UHS ® and MEK mixed well. Apply this at 200 sq ft/gallon (18 sq mtr/gallon); 8 mils wet/3.6 mils dry (to penetrate into pores. Allow 4 hours to dry and ventilate well, then apply 2nd application of 100% TOTALSEAL UHS ® at 200 sq ft/gallon. Wait 24 hours and apply the last coat of TOTALSEAL UHS ® at 200 sq ft/gallon.

Note: Surface and ambient temperatures will determine cure time. Introduction of heat over surface will enhance the cure time.
Induction Period: 30 minutes at 70°F (21°C); No induction time is necessary over 90°F (32°C).
NOTE: It is critical that each coat of TOTALSEAL UHS ® be firmly adhered to the substrate before the next coat is applied. Depending on ambient and surface temperatures, it may take longer than a 24 hour recoat application window.

  1. After completion, spray systems should be flushed and cleaned with MEK or other comparable solvents.
  2. After completion, brushes and rollers can be cleaned with MEK or comparable solvents, stored and reused.

Do not apply to chlorinated rubber. Even after sandblasting, the chlorination can attack the solvents and brittle the coating.

Applicator must, at all times during use, wear a Bureau of Mines-approved, 2-stage (charcoal and cotton) paint spray respirator, designed for removal of organic vapors, or a fresh air-supplied type of respirator. Protective clothing and protective eye-wear goggles) are recommended.
