Details of Polymer Modified Grout
Polymer Modified Grout (PMG) is a type of grout that incorporates polymers (either in liquid or powder form) into traditional cement-based grouts to improve performance characteristics. It is commonly used in both residential and commercial tiling applications, particularly where enhanced strength, flexibility, water resistance, or chemical resistance is required.
What Is Polymer Modified Grout?
Polymer Modified Grout is essentially a cement-based grout enhanced with polymeric additives (such as acrylics, vinyl acetates, or latex). These polymers modify the behavior of the grout by improving its properties over conventional grout.
Components of PMG
Cement (usually Portland cement) – the base binder.
Sand or filler – adds bulk and structure.
Water-retaining agents – help reduce shrinkage and cracking.
Polymers (latex or dry powder) – provide improved bonding and flexibility.
Pigments (optional) – for color customization.
Water – for mixing (if polymers are in powder form).
Key Properties and Advantages
Property Benefit
Improved Adhesion Better bond to tiles and substrates.
Flexibility Accommodates minor substrate movement; useful in areas subject to thermal expansion or vibration.
Water Resistance Reduced water absorption; ideal for wet areas like bathrooms, kitchens, and swimming pools.
Chemical Resistance Improved resistance to mild acids and cleaners.
Crack Resistance Less prone to shrinkage and cracking compared to traditional grout.
Durability Longer lifespan under harsh conditions.
Types of Polymer Modified Grout
Sanded PMG
Contains fine sand particles.
Used for wider joints (≥ 1/8 inch or 3 mm).
Suitable for floors and exterior applications.
Unsanded PMG
No sand or very fine particles.
Used for narrow joints (< 1/8 inch or 3 mm).
Ideal for walls, polished stones, and glass tiles.
Epoxy-Modified PMG
A hybrid system combining epoxy resins and polymers.
Offers superior stain, chemical, and abrasion resistance.
Typical Applications
Tiling in bathrooms, kitchens, and showers
Swimming pools and fountains
Exterior tiling
Commercial kitchens
High-traffic areas (e.g., malls, hospitals)
Limitations
More expensive than conventional grout.
May require additional curing time.
Requires careful mixing and application to avoid polymer separation or poor performance.
Limited UV resistance depending on the type of polymer used.
