Overview
What is Grout?
Grout is the material used to fill the joints between tiles, providing structural support, preventing water infiltration, and completing the visual appearance of tile installations. The right grout choice significantly impacts both durability and aesthetics.
Origin & Sourcing
Grout technology has evolved from simple cement mixtures to sophisticated polymer-modified and resin-based formulas. Modern grouts offer superior performance, stain resistance, and color consistency compared to traditional products.
Composition
Cement grout consists of Portland cement, aggregite (for sanded), and polymers. Epoxy grout contains epoxy resins and silica fillers. Urethane grout uses polymer resins for flexibility and water resistance.

Use Cases
Best applications
Where grout performs best based on our installation experience.
Shower Floors
Epoxy or urethane best for waterproof, stain-free joints
Kitchen Backsplash
Stain-resistant grout prevents grease discoloration
Bathroom Floors
Polymer-modified cement or epoxy for wet areas
Pool Surrounds
Epoxy grout resists chemicals and constant water
Wall Tiles
Unsanded grout for narrow joints, sanded for wider
Natural Stone
Use unsanded to avoid scratching soft stone

Common Questions
Frequently asked questions
Expert answers about grout.
What is the best grout for showers?
Epoxy grout is the best choice for showers - it's completely waterproof, mold-resistant, and never needs sealing. Urethane grout is a close second and easier to apply. Both outperform cement grout in wet environments.
How often should grout be sealed?
Cement grout should be sealed annually in wet areas like showers, and every 2-3 years in other locations. Epoxy and urethane grouts never need sealing. A water droplet test tells you when resealing is needed.
Why is my grout cracking?
Grout cracks due to improper mixing, too-quick drying, substrate movement, or inadequate expansion joints. In corners and where surfaces meet, caulk should be used instead of grout to accommodate movement.
Can I change my grout color?
Yes, grout can be recolored with grout stain/colorant or removed and replaced. Staining is less labor-intensive but doesn't work well for dramatic color changes. Complete removal and regrouting provides the best results.
