Unitex® Uni-Substrate Sealer is a pigmented substrate coating and is based on acrylic co-polymers in a water emulsion specifically formulated for compatibility in the highly alkaline cement environment as a colour matching sealer. 

Unitex® Uni-Substrate Sealer is applied to masonry rendered surfaces to provide colour uniformity to the subsequent Unitex® surface applied finishing coat. 

Unitex® Uni-Substrate Sealer is supplied in ready-to-use 15L pails. 

Approximate coverage per pail is 50-60m².

Site Requirements:

  • Provide complete system in-situ sample for Architect and Builder approval
  • Apply only onto clean, dry and well-bound masonry surfaces
  • Mask up all adjoining surfaces, windows, and non-masonry works
  • All mastic-filled expansion joints to be complete and dry prior to Unitex® Uni-Substrate Sealer application
  • No cold joints – complete all areas floor to floor, and from control joint to control joint

Product Performance and Application

Unitex® Uni-Substrate Sealer is for exterior and interior use and offers resistance to early hydrolysis and rain penetration into the substrate, as well as protecting and adding colour to the base substrate. To reduce blushing through of the substrate, Unitex Uni-Substrate Sealer is the ideal solution. 

Unitex® Uni-Substrate Sealer is compatible with all Unitex® acrylic renders and surface applied coatings. 

When applying Unitex® Uni-Substrate Sealer please consider the following:

  • Apply between 100C and 350C ambient temperature
  • Allow 2 hour drying time before top coating in Summer, and 4 hours in Winter
  • Generally 1 coat is required (or more if substrate is not fully sealed)
  • Roller and spray applied
  • Use water if thinning product is required, and in cleaning tools
  • Slows the drying of the subsequent coat and to be a consideration when rain and cooler conditions is a possibility

Apply only after all renders, patching repairs and expansion joint mastic are dry and cured
