Grout

Varieties:
– Tiling, flooring, resin, nonshrinking, and thixotropic grouts are common types.
– Enhancing admixtures improve cement-based materials’ quality.
– Tiling grout fills spaces between tiles, with sanded and unsanded varieties available.
– Structural grout is used in reinforced masonry to fill voids and secure reinforcing steel.
– Nonshrinking grout is placed beneath metal bearing plates for consistent bearing surfaces.

Tools and Treatments:
– Grout saw or scraper removes old grout, usually made of tungsten carbide.
– Grout float smooths grout lines, typically made of rubber or soft plastic.
– Grout sealer resists water, oil, and acid-based contaminants when applied over dried grout.
– Grout cleaner removes dirt and dust from grout lines.
– Die grinder is used for faster removal of old grout compared to a grout saw.
