HSR – High Strength Render

Engineered for Strength and Versatility SGM High Strength Render (HSR) is formulated to outperform standard mortars by delivering exceptional bond strength, improved workability, and reliable consistency from batch to batch. Its advanced cementitious formula simplifies installations by eliminating the guesswork and variability of on-site blending. Key Benefits: Superior compressive and flexural strength Designed for both thin bed and thick bed applications Consistent, factory-blended formula ensures quality control Eliminates costly job-site additives Excellent for wet area applications such as pools, spas, and fountains Can be used as a superior substitute for Type S or Type N mortars Ideal Uses: Swimming pool interiors Spa surfaces Water features Fountains Wet area substrates Application Guide: Surface preparation: Clean, stable, and free of contaminants. Mixing: Use clean potable water. Follow the manufacturer’s recommendations for water ratio. Application: Apply with a trowel or appropriate spray equipment, depending on thickness. Curing: Follow the recommended cure times before applying subsequent coatings or exposing to water. Always refer to the manufacturer’s guidelines for complete mixing and application instructions. Frequently Asked Questions Can HSR be used for pool resurfacing? HSR is designed as a render substrate for pool interiors but should be top-coated with a suitable pool finish or coating. Is it safe for constant water immersion? Yes, once fully cured and properly top-coated, HSR is ideal for submerged applications. Does HSR require any additives? No additional job-site additives are needed. HSR is factory-blended for optimal consistency and performance.
