Metzger/ McGuire, Joint Filler, SRG Surface Refinement Grout, 2 Gallon Kit, Ryno Gray (COLOR PACK ORDERED SEPARATELY)

SRG is a two-component, 95% solids structural polyurethane/polyurea hybrid. When cured, SRG is a rigid structural polymer. SRG was developed to fill/repair concrete floor surface imperfections such as air holes, popouts, surface pitting, scratches and gouges, etc. SRG is designed for use in commercial or retail polished concrete floors where final building temperatures are 32 deg F (0 deg C) to +120 deg F (49 deg C). Our industrial and polished concrete floor joint fillers and repair and maintenance products have been setting the standard in our industry for decades.

• SRG can also be mixed with sand aggregate or similar to create a repair mortar suitable for joints, cracks and larger surface defects
• Designed for use with a color pack
• SRG is designed primarily for fine grouting and not for use in repairing surface defects larger than 1/2 in unless modified with sand aggregate or similar
• Depending upon surface conditions and/or environmental conditions, more than one coat of product may be required
• SRG may exhibit slight color change or shifting if exposed to UV emitting lighting sources
• SRG will exhibit a moisture reaction on damp or wet surfaces, repair area should be dry
• Rapid-set formula allows for quick access to floor areas and grinding as early as 40 min after application (at 70 deg ) or 20 min 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
• Compliance and Certifications: ASTM Standards
