    What the experts have to say

    Application
    Guidelines
    SX300 NA should be applied directly after mixing by pouring a ribbon of material along the wet edge and then trowelled to form a smooth, even finish. The effective use of spike rolling can reduce visible trowel marks.
    • Water resistant: can be used for pre-smoothing

    • Short setting and cure time, facilitating fast track programs and minimising disruption

    • Low odor and protein free

    • Self-priming on most surfaces

    • Excellent adhesion to a wide range of common flooring substrates, including: concrete, sand/cement screeds, flooring grade asphalt, TREMCO surface DPM’s, etc.
