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.
