    Installation Guidelines

    Concrete: Apply only to clean, dry and sound concrete substrates that are free of all coatings, sealers, curing compounds, oils, greases or any other contaminants. Concrete that has been contaminated with chemicals or other foreign matter must be neutralized or removed. Remove any laitance or weak surface layers. Concrete should have a minimum surface tensile strength of at least 300 PSI, as verified by an Elcometer test. Surface profile shall be CSP-3 to CSP-5 meeting ICRI (International Concrete Repair Institute) standard guideline #03732 for coating concrete, producing a profile equal to 60-grit sandpaper or coarser. Prepare surface by mechanical means to achieve this desired profile. Refer to DE NEEF® Surface Preparation Guidelines for more details.

    Steel: For steel surfaces, a “White Metal” abrasive blast with an anchor profile of 2-4 mils in accordance with Steel Structures Painting Council Specification SP-5-63 or NACE No. 1 is required for immersion service. For splash and spillage exposure, a “Near White”, SP-10-63 or NACE No. 2 is required.

    1. DeneSeal 5050 Primer can be applied by brush or roller.
    2. Apply DeneSeal 5050 Primer at a rate not to exceed 75 sq. ft./0.25 gallon unit for concrete and 100 sq. ft./unit for steel. Rolling coating is an alternate method of application, but coverage will be significantly less.
    3. The curing time for DeneSeal 5050 Primer is between 2 and 36 hours. The first coat of DeneSeal P-2235 must be applied within 36 hours of priming. If more than 36 hours elapse, the primer must be reapplied.
    4. Use of a brush will allow for joints to be primed before the application of DeneSeal P-2235.
    5. For best results, clean tools and equipment with a nonflammable and non-evaporating cleaner. Always wear gloves when using this product.
