New Types of Grout: Polymer-Based Alternatives to Sanded and Unsanded Grout
Grout technology has advanced significantly in recent years, offering improved performance, durability, and ease of maintenance. Traditional sanded and unsanded cement-based grouts have long been the standard, but they require sealing, can crack over time, and are prone to staining. The latest innovation in grout materials includes polymer-based alternatives that eliminate many of these drawbacks while providing superior flexibility, adhesion, and water resistance.
In this blog, we explore the new generation of polymer-based grouts and how they are revolutionizing tile installations.
1. What Are Polymer-Based Grouts?
Polymer-based grouts are formulated with advanced resin and plastic compounds, creating a flexible and durable material that offers greater performance than traditional cementitious grouts. Unlike epoxy-based grouts, polymer grouts provide excellent ease of use without the challenges of fast curing times and difficult application.
Key Benefits of Polymer-Based Grouts:
No Need for Sealing – Polymer-based grouts are non-porous, making them resistant to moisture, stains, and bacteria without requiring additional sealers.
Increased Flexibility – These grouts can expand and contract with structural movement, reducing the risk of cracking.
Better Adhesion – Polymer-enhanced formulas bond strongly to tile surfaces, reducing shrinkage and ensuring longevity.
Improved Water Resistance – Ideal for wet areas such as showers, pools, and kitchens, preventing water infiltration and mold growth.
Stain Resistance – Enhanced protection against dirt, grease, and everyday spills.
Faster Cure Times – Many polymer-based grouts cure quickly, allowing faster project completion.
2. Types of Polymer-Based Grouts
Several polymer grout formulations are available, each with specific advantages for different tile applications.
A. Urethane Grout
Comes pre-mixed, making it easy to apply without additional water or mixing.
Highly flexible and resistant to cracking.
Excellent for both residential and commercial applications.
Stain- and water-resistant, making it ideal for high-moisture areas.
B. Acrylic-Modified Grout
Enhanced with acrylic additives for increased durability and flexibility.
Provides better adhesion than traditional cement grout.
Easier to clean and maintain over time.
C. Hybrid Cement-Polymer Grouts
Combines traditional cement grout with polymer additives for improved performance.
More resistant to moisture and cracking than standard sanded or unsanded grout.
Suitable for both interior and exterior tile installations.
3. When to Choose Polymer-Based Grouts
Polymer-based grouts are suitable for a wide range of applications, including:
High-Traffic Areas – Kitchens, entryways, and commercial spaces where durability is essential.
Wet Environments – Showers, pools, and outdoor patios due to their waterproof nature.
Flexible Substrates – Ideal for installations over surfaces that experience slight movement, reducing the risk of grout cracking.
Stain-Prone Areas – Areas exposed to spills and heavy cleaning, such as restaurant floors or kitchen backsplashes.
4. Installation Tips for Polymer-Based Grouts
While polymer-based grouts offer numerous advantages, proper installation ensures the best results:
Read Manufacturer Instructions – Each product has unique mixing and application requirements.
Use the Right Tools – Apply with a rubber float and clean excess grout promptly with a damp sponge.
Work in Sections – Polymer grouts may have a faster curing time, so work in smaller sections to avoid dried-on residue.
Allow Proper Curing Time – Follow recommended curing guidelines to ensure full strength and performance.
5. Final Thoughts
Polymer-based grouts represent the next evolution in tile installation, offering superior durability, stain resistance, and ease of maintenance compared to traditional sanded and unsanded grout. Whether you are installing tile in a high-moisture area, a high-traffic space, or simply want a low-maintenance solution, polymer-based grouts are a game-changer.
