    Large Surfaces
    Use an airless sprayer with a spray tip size between .035mm to .051mm.

    Application Best Practices

    1) Step One: Prepare the surface and confirm surface moisture is less than 25%. Remove dirt, grime, efflorescence, lime run, construction debris, form oils and release agents, chalked materials, loose and peeling paint, mold, mildew, etc. All cracks should be pointed or caulked.
    2) Step Two: Perform a test application to confirm fit and finish.
    3) Step Three: Apply the product according to It’s TDS.
    4) Step Four: Let cure.
    5) Step Five: Perform post application test to assure results are achieved.

    Benefits of Concentrates and How to Mix

    The benefits of specifying Concentrates:

    • Reduces carbon footprint
    • Reduces job site and landfill waste
    • Reduces worker and supply chain fatigue
    1. Refer to the description on the packaging for dilution ratios.
    2. Pour contents of concentrate into an empty container. The container size should be the size of the finished amount of product.
    3. Fill the container with clean water – we recommend distilled water for best results.
    4. Mix lightly with a stir stick.

    Substrate Uses and Anticipated Coverage Rates

    Substrate porosity varies due to type of substrate and/or the age of the surface and its exposure to weathering. As a result, coverage rates may also vary. In addition, in certain applications, two coats may be required. Please contact us for coverage estimates. Best practices are to first perform a test application on the substrate, followed by a rilem tube test to ensure adequate coverage/absorption.

    Refer to the product TDS for Surface Preparation and Application Methods.
