General purpose smoothing compound.
TREMCO SX300 NA is a two-part, general purpose, smoothing underlayment for internal applications. It is manufactured from cementitious powder and liquid latex dispersion and is suitable for a wide range of common flooring substances, including: concrete, sand/ cement screeds, flooring grade asphalt and Treadfast surface DPM’s.
The material is self-levelling and self-priming on most surfaces. In some cases it may be necessary to prime with Treadfast Uniprime (porous substrates) or Treadfast Epoxyprime (non-porous substrates).
Thicknesses of 6 mm to feather edge can be applied, dependent on surface profile. Thicknesses of 8 mm to 30 mm can be achieved by incorporating an equal volume of 3 mm granite chippings.
