SRG Surface Refinement Grout

SRG  is a two-component, 95% solids structural polyurethane/polyurea hybrid. When cured, SRG is a rigid structural polymer
with a Shore D Hardness of 70-75. SRG was developed to fill/repair micro-level concrete floor surface imperfections such as air holes, sand aggregate pops, surface pitting, scratches and gouges, etc. SRG can also be mixed with sand aggregate or Rapid Set® TRU® and TRU® PC to create a repair mortar suitable for joints, cracks, and larger surface defects. SRG is designed for use in commercial or retail polished concrete floors where final building temperatures are 0°C to + 49°C. SRG is designed for use with a Colour Pack. An Accelerator Pack which reduces potlife and grind time is also available.



The SRG system is designed to be used only with the addition of one of 12 available Colour Packs. There is no Neutral or Clear/
Natural colour available. If the SRG kit is mixed without a Colour Pack, the cured material will have a milky white appearance. Colour packs must be thoroughly blended into SRG Part A (Polyol) prior to mixing the SRG Part A (Polyol) with the SRG
Part B (ISO) at a 1:1 ratio. A Colour Pack is included as part of the SRG 7.6L Kit and 5 Colour Packs as part of the SRG 38L Kit. Available colours include: Black, Black Fox, Brevity Brown, Cardboard, Dovetail Gray, Intellectual Gray, Less Brown, Mocha Brown, Porpoise, Ryno Gray, Tanbark and Warm Stone.



  • Available in 12 colours to best camouflage floor surface pitting and surface imperfections  
  • Rapid-set formula allows for quick access to floor areas and grinding as early as 40 minutes after application (@21°C) or 20 minutes with Accelerator Pack.
  • Low viscosity allows for penetration into very small surface pits and imperfections  
  • Yields a smoother, denser floor surface which can aid in achieving higher gloss and DOI values.
