Crystalline waterproofing

The crystalline waterproofing compound is once mixed with water (as per manufacturer instruction) and applied over the prepared surface it will create the insoluble crystals in the pores of the concrete surface and blocks the penetration of water through pores. Whenever these insoluble crystals getting in contact with water it will further develops into more…

Tile grout

Tile grout is used for filling the gaps between tiles. Tile grouts are good in following aspects, 1. Permitting thermal expansion & contraction 2. Controlling water intrusion 3. Available in various colours to suits the tiles Why not white cement? Few years before, white cement has been used for filling the tile joints. But after…

Quantity calculation for ingredients of concrete

How to calculate the required quantity of ingredients for 1m³ concrete of grade M20 (Volume batch)? Given data: Mix ratio for M20 is 1:1.5:3 (Cement: Fine aggregate: Coarse aggregate) Solution: Volume of compacted wet concrete = 1m³ For 1m³ of compacted wet concrete we have to add extra 53% of dry ingredients So total volume…

Tile Spacers

Tile spacers are small pieces of plastic that allow us to achieve consistent spacing between the tiles when installing a floor or wall. Tile spacers are available in different sizes, Since the minor dimensional variation is possible in tiles, Tile spacers helps in getting proper tile joints & their line. Spacers enable a higher degree…

Paper Joint vs Spacer Joint

Paper Joint: Placing tiles without any gap in between is called as Paper joint. Advantages: Sourcing of tile masons for paper joint is easy, because most of the tile masons have experience in this system from many decades. Additional tools like tile spacers are not required Tile grouting activity is simple and consumption of tile grout…

Tile laying – Conventional method vs Adhesive method

Conventional method (Thick bed system) Fixing of tiles in fresh cement mortar bed (thickness 10mm & above) with cement slurry/paste is called as “Conventional method”. This is also called as Thick bed system, because fresh bed for fixing is more than 10mm.     Adhesive method (Thin bed system) Fixing of tiles in harden base…

Hacking

Most of our concrete surfaces are smooth in nature. These smooth surfaces are not suitable for further masonry works – Block work & Plastering. We need to prepare these surfaces such a way that the bonding between concrete and upcoming mortar is optimum. The same can be achieved by Hacking process or by Chemical treatments. In this…

Tile Adhesives

Tile Adhesive is a ready mixed polymer modified cement based bonding material used for tile fixing in floors and walls. We generally use Cement Mortar and Cement slurry / Cement paste for fixing tiles in conventional method. Using Tile Adhesive is little advanced system and have few advantages over the cement. Advantages: Tile Adhesives have…
