How Do I Clean and Repair Grout? | DIY Basics via Lowe's Home Improvement
What is Grout?
Grout is a dense substance that begins with a liquid-like flow and hardens after application. It is frequently used to fill gaps or to reinforce existing structures.
It is typically a mixture of water, cement, and sand. Common household applications include filling the spaces between tiles on shower floors and kitchen backsplashes.
Grout Properties and Uses
When correctly mixed and applied, grout forms a water-resistant seal, unlike other structural pastes such as plaster or joint compound.
Grout can be tinted to match visible areas and may include fine gravel for filling larger spaces. It is also used in pressure grouting and embedding rebar in masonry walls.
Grout vs. Mortar and Caulk
While both grout and mortar are applied as thick suspensions that harden, grout is distinguished by its low viscosity. This thin consistency allows it to flow readily into gaps.
Mortar, in contrast, is thick enough to support its own weight and the weight of masonry placed above it. Grout is also distinct from caulk in its composition and application.
Key takeaways
- Grout is a cement-based mixture used to fill gaps between tiles and reinforce structures.
- Properly applied grout creates a water-resistant seal, making it suitable for showers and kitchens.
- Grout's low viscosity allows it to fill small gaps effectively, differentiating it from thicker mortar.
