General Questions
Tile adhesive is a polymer-modified, ready-to-use bonding material designed for fixing tiles on floors and walls. It offers superior adhesion strength, flexibility, and long-term durability compared to conventional cement-sand mortar. The composition typically includes Adhesives comprise reactive polymers, solvent or water carriers, mineral fillers, tackifiers for initial grip, plasticizers for flexibility, and additives for durability, UV resistance, and microbial protection.
- Cement-Based Tile Adhesive:
Composed of cement, graded fillers, and polymer additives, this adhesive is ideal for fixing ceramic, vitrified, and porcelain tiles on concrete or plastered surfaces. Commonly used in interior and exterior floor and wall tiling, including bathrooms, kitchens, and terraces. - PU-Based (Polyurethane) Tile Adhesive:
A two-component, solvent-free polyurethane adhesive known for its high flexibility, chemical resistance, and waterproofing properties. Suitable for metal, glass, wood, and wet area substrates, as well as industrial applications and expansion joints where movement and vibration resistance are critical.
Choosing the right adhesive depends on Four key factors:
- Tile/Stone Size – (2×2 ft, 4×2 ft, 6×4 ft & 10×4 ft)
- Tile/Stone Type – (ceramic, vitrified, porcelain, natural stone, glass, etc.)
- Surface Type – (concrete, cement board, old tiles, plywood, etc.)
- Application Area – (floor, wall, bathroom, kitchen, outdoor, etc.)
Polymer-Modified Type-2 Adhesive.
Polymer-Modified Type-3 Adhesive.
- Follow manufacturer mix ratios.
- Use notched trowels suited to tile size; butter back large-format tiles for full coverage
Substrate must be clean, dry, free of loose particles or grease.
Absolutely for exteriors and facades to accommodate thermal movements; neglect can cause cracking.
Most bagged adhesives keep potency for ~12 months if sealed and stored dry.
Yes, with compatible adhesive like Type-2 for internal floor only, but ensure surface is clean and hatched.
On average, a 20 kg bag of tile adhesive covers around 22–25 sq ft, depending on the tile size, surface level, and the trowel notch size used.
- With a 6 mm trowel: approx. 25 sq ft
- With a 10 mm trowel: coverage may reduce to around 18–20 sq ft
Tile grout is a specially formulated material used to fill the gaps (joints) between installed tiles. It helps prevent water seepage, accommodates slight expansion or contraction, and enhances the overall strength and appearance of the tiled surface.
- Cement Grout is a traditional grout made from a mixture of cement, sand, and water. It is suitable for general applications with low to moderate foot traffic and minimal thermal variation.
- Epoxy Grout is made from epoxy resins and a hardener, making it highly resistant to stains, chemicals, and water. It is ideal for areas with high foot traffic, frequent cleaning, and significant temperature variation, such as kitchens, bathrooms, and commercial spaces.
Grouting should be done 24 hours after tile installation, once the adhesive is fully cured.
Yes, especially in wet areas like bathrooms, balconies, and terraces. Waterproofing protects against water damage and increases tile life.
Yes, on dusty or smooth surfaces, applying primer ensures better bonding.
Yes, with proper surface treatment and flexible adhesives like- PU ADHESIVE.
Wrong adhesive for substrate/tile, poor mixing, insufficient coverage, no back-buttering, forgetting spacers, grout too soon or skipping waterproofing.
Traditional cement slurry is slow to set, creates a messy application, requires water curing, and lacks the bonding strength needed for large or heavy tiles. Modern tile adhesives provide faster setting, better precision, and superior holding capacity without the need for curing.
No, the surface must be dry before application. Moisture can compromise the bonding strength and curing process of the adhesive.
Not always. While some adhesives are suitable for both indoor and outdoor use, outdoor areas require adhesives that can withstand weather changes, moisture, heat, and movement.
- Choosing an incompatible adhesive for substrate or tile type.
- Neglecting spacers, incorrect mix, insufficient trowel notch, or skipping back-buttering on large-format tiles.
Use tile and grout cleaners like: -TS Chemical -Tile Cleaner. Avoid acid on sensitive surfaces.
Yes, sealing grout increases its resistance to stains and water, especially for cementitious grouts.
Possible causes include poor surface prep, wrong adhesive choice, or poor mixing. Follow brand instructions and site conditions properly.
No, never add water or re-temper adhesive once it has started to set. This weakens the bonding strength. Always mix fresh adhesive in small, manageable batches.
Yes, most are non-toxic and VOC-compliant. Use appropriate PPE (Personal Protection Equipment) during application.
Yes, with heat-resistant adhesives. Always check technical data sheets for temperature resistance.
