    Preparation and application

    Substrate and preparation

    Concrete substrates to be coated must be sound and exhibit a minimum compressive strength of 25N/mm² and a minimum of 1.5N/mm² tensile strength for the application of the proposed system. The profile and levels must be appropriate for the application of the proposed system, capable of bearing loads, free of cracks and voids, and free from laitance, dust and other contamination.

    The substrate must be dry to 75% relative humidity and free from rising damp, ground water, oil and other contamination. Should there be rising damp, ground water problems or impurities such as penetrated oils, etc., please refer to the ASP Technical Team for a suitable and appropriate substrate preparation guideline or solution. The substrate may be prepared by blasting or diamond grinding to remove laitance. Irregularities, small damages and cracks must be repaired with an epoxy filler.

    Before application of the flooring system, anchor grooves must be cut approximately 4mm deep x 4mm wide and 25mm on either side of the expansion joints, saw cuts and edges of the floor.

    Primer

    Mix Base A and Hardener B with a low speed drill fitted with a spiral mixing blade for approximately 3 minutes to obtain a homogeneous mixture. Ensure excessive air is not introduced while mixing. The mixed material must be applied within 15 minutes at 20ºC. Apply immediately after mixing with a roller or double-lipped rubber squeegee, working the resin well into the substrate, permeating any surface irregularities. On porous substrates, apply further resin until the substrate is completely wetted out. Avoid any ponding of the primer. Broadcast into the wet primer with the appropriate size scatter sand at 1kg/m². When cured, sweep off or vacuum the loose scatter sand.

    Topcoat

    Mix Base A and Hardener B together in a rotatory pan mixer or with a low speed drill fitted with a spiral mixing blade for approximately 2 minutes. Slowly add the pigment pack and mix for a further 1 minute to obtain a homogeneous mixture. Finally, add in the Filler C and mix for an additional 2 minutes. Ensure excessive air is not introduced while mixing. The mixed material must be applied within 10 - 15 minutes at 20°C. Apply immediately after mixing with a 5mm precision coating rake. Allow to stand for approximately 5 minutes, then roll in one direction with a bubble buster / spike roller to release any trapped air. For more detailed information on substrate requirements and preparation, priming and application of the top coat, please refer to the product’s method statement.

    Maintenance

    Clean all spillages on ASP-creteSL immediately to maintain its appearance and lifespan. Clean the floor regularly with a rotary brush or mechanical scrubber and a suitable detergent. See how to clean and maintain a resin floor.

    Health and safety

    Applicators must use appropriate personal protective equipment. Dispose of used and empty packaging, solvents and washings in line with local environmental, health and safety by-laws. Refer to the product's material safety data sheet for detail.

    For full substrate requirements, priming and application of the top coat, refer to the product's method statement or ask our technical team.
