Tile Adhesives
1. What is tile adhesive, and why can't I just use cement and sand?
Tile adhesive is a ready-to-mix product made with cement, fine sand, and special additives that help it grip firmly. Plain cement and sand is the old method. It dries unevenly, needs the tiles to be soaked first, and often leaves hollow spots under the tile. Adhesive gives a stronger, thinner, more even bond.
2. Can I fix new tiles over old tiles?
Often yes, if the old tiles are firmly stuck, clean, and free of oil or wax. Loose or hollow-sounding tiles must be removed first. We recommend a primer or a strong adhesive for this job.
3. Which adhesive should I use for my tiles?
It depends on the tile and the place:
- Standard adhesive: ceramic wall and floor tiles in dry indoor areas.
- Improved (polymer-modified) adhesive: vitrified, porcelain, and large tiles, and wet or outdoor areas.
- Flexible adhesive: places with movement or temperature change, such as balconies and terraces.
- White adhesive: marble, light stone, and glass, so the colour is not stained.
If you are not sure, tell us your tile type and location, and we will recommend the right one.
4. How long do I have to place the tile after spreading adhesive?
This is called "open time." It is usually around 20 to 30 minutes, but it changes with weather and the product. Spread only a small area at a time. If the surface forms a skin, scrape it off and spread fresh adhesive.
5. How much adhesive do I need?
Coverage depends on the tile size, the trowel notch, and how flat the surface is. As a rough guide, one square metre needs a few kilograms of powder. Share your area and tile size with us, and we will give you a proper estimate, with a little extra for wastage.
6. Do large tiles need anything special?
Yes. Large tiles need a stronger, improved adhesive, a larger notched trowel, and a thin layer of adhesive on the back of the tile as well (called "back buttering"). This avoids hollow spaces that can crack the tile later.
7. How long before I can walk on the floor or apply grout?
In most cases, light foot traffic is fine after about 24 hours, and grouting can be done after 24 hours. Full strength takes several days. Exact timings are on the product pack, so please follow them.
8. Can I add extra water to make it easier to spread?
No. Too much water weakens the bond. Always use the water quantity printed on the bag.
Waterproofing Systems
1. Why is waterproofing needed if my building is already well built?
Concrete and masonry are never completely waterproof. Water slowly finds its way through tiny cracks and joints. This leads to damp walls, peeling paint, rusting steel, and weaker structures over time. Waterproofing is far cheaper to do properly at the start than to repair later.
2. Which areas of my home need waterproofing?
Bathrooms, toilets, kitchens, balconies, terraces, roofs, water tanks, swimming pools, basements, and outer walls that face rain.
3. What types of waterproofing are available?
- Cementitious coatings: brushed on, good for bathrooms, tanks, and basements.
- Flexible liquid membranes: good where small cracks and movement are expected, like terraces and balconies.
- Crystalline systems: go into the concrete and block water from within, often used in basements and tanks.
- Sheet membranes: ready-made rolls used on large roofs and below-ground structures.
The right choice depends on the area, so we help you pick the one that suits.
4. Should waterproofing be done before or after tiling?
Before. The waterproof layer goes on the prepared surface, and the tiles are fixed on top of it using a suitable adhesive.
5. How high should waterproofing go on bathroom walls?
It should run up the walls beyond the floor level, usually at least 150 to 300 mm, and cover the full height inside shower areas. Corners and pipe openings need extra attention.It should run up the walls beyond the floor level, usually at least 150 to 300 mm, and cover the full height inside shower areas. Corners and pipe openings need extra attention.
6. How do I know the waterproofing has worked?
Do a water-holding (flood) test. Block the drain, fill the area with a few centimetres of water, and leave it for 24 to 72 hours. Check the ceiling or wall below for any dampness before you start tiling.
7. How long does waterproofing last?
With the right product, proper surface preparation, and correct application, it can last many years. Poor preparation is the most common reason for early failure, which is why we stress the steps as much as the product.
8. Can I apply it over old waterproofing or leaking surfaces?
Sometimes, but not always. The surface must be cleaned, cracks must be repaired, and any loose old material removed. We will guide you on whether repair or a fresh start is better.
