When it comes to tile installations—whether in kitchens, bathrooms, balconies, or commercial spaces—the focus often remains on the tile’s design and finish. However, beneath this visible beauty lies a critical yet frequently overlooked element: grout. Acting as the invisible support system, grout fills the gaps between tiles, ensuring structural integrity, durability, and a flawless finish. Among various options, cementitious grout stands out as the most widely trusted choice for both residential and commercial applications.
What Is Cementitious Grout?
Cementitious grout is a dry, powder-based mix primarily composed of Portland cement, fine aggregates, and performance-enhancing additives. When combined with water, it forms a paste used to fill the joints between tiles. It’s designed not only to bind but to protect the tile joints from any foreign particle or water penetration in both residential and commercial settings.
Types of Polymer-Modified Cementitious Grout
Enhanced with additives for improved flexibility, water resistance, and adhesion, ideal for areas prone to moisture and movement, such as bathrooms, kitchens, balconies, and high-traffic zones.
- Unsanded Grout (Cement & Polymer): Best for narrow joints (below 3 mm), especially in polished tiles or vertical applications.
- Sanded Grout (Cement, Sand & Polymer): Formulated for comparatively wider joints (3mm – 7 mm) than unsanded grout. The inclusion of fine sand increases mechanical strength and minimises shrinkage.
Why is Cementitious Grout So Important?
- Stability: Locks tiles in place and ensures even load distribution.
- Water Resistance: Properly applied grout prevents moisture penetration, protecting substrates from long-term damage.
- Thermal Flexibility: Protects tiles from cracking or debonding due to thermal expansion and contraction by self-adjustment or cracking.
- Aesthetic Versatility: Available in multiple colours, allowing homeowners and designers to enhance the beauty of tiled surfaces.
- Easy to Use: Simple to mix, apply, and clean—ideal for both professionals and DIY enthusiasts.
- Cost-Effective: A budget-friendly solution, especially suitable for yearly/bi-yearly renovations.
Applications of Cementitious Grout
Cementitious grout is applicable to any place where it can be applied to internal/ external surfaces, swimming pools, etc.
How to Apply Cementitious Grout
- Mix 1 kg of grout powder with 300–350 ml of water.
- Stir thoroughly for 3–5 minutes to achieve a lump-free, smooth consistency.
- Apply the mixture using a rubber float or spatula, pressing it firmly into the joints.
- Remove excess grout before it hardens.
- After 30 minutes, clean the surface with a damp sponge or cloth.
- Allow 3 days curing for long-lasting results and, if necessary, apply a grout sealer.
