Cement Tile Adhesives and What We Need to Know

Traditionally, tiles with a cement and sand slurry were enough to fulfil the job. However, there are certain drawbacks to this strategy. Because cement shrinks while it dries, it leaves empty spaces beneath the tile surface. These are weak floor points, and any impact on them results in tile chipping or breaking. Tile Adhesives are the best choice for a long-lasting and trouble-free tile installation.

Choosing the correct tile adhesive among various tile adhesives available in the market is somehow arduous. It is because each tile bond differs based on the use. There will be a different recipe, various mix ratios, and a variable quality of ingredients for each of these.

Ressichem offers a comprehensive range of tile bonds, perfect for most tiles on bulk surfaces.

Types of Cement Adhesives

1. C1 Adhesives Based on Cement

C1 adhesives are basic cement-based adhesives that are often incompatible with porcelain tiles, the most prevalent form of floor tile.

2. Cement-Based Adhesives (C2 Adhesives)

Adhesives have their polymers changed, resulting in higher adhesion and binding strength. It also gives some flexibility as well as water-repelling properties. This adhesive is appropriate for most tile varieties and a wide range of backdrop surfaces.

Suffixes and Additional Bond Adhesive Properties

  1. F = This tile adhesive has a Fast Setting or Rapid Setting, which reduces curing time and allows you to grout and finish your job faster.
  2. T = Thixotropic or Slump resistant/Non-slip adhesive. It is especially handy for wall tiling since the glue does not sag with gravity and weight.
  3. E = Extended Working Time or Pot Life, which can apply to both rapid setting and standard-setting adhesives. Extended pot life means you do not have to rush, which is especially useful when tiling larger areas or projects with a complex design that necessitates a lot of tile cutting.
  4. S1 = The S rating refers to the adhesive’s deformability. S1 tile adhesives are appropriate for most tiling surfaces with low movement or vibration, such as firmly braced timber floors. S1 adhesives are the industry standard tile adhesives for flooring because they are flexible and provide a solid support for your tiles.
  5. S2 denotes that the product is a Highly Deformable adhesive. Although a highly deformable adhesive appears to be the appropriate product for epoxy flooring with more movement, the S2 adhesive does not give as much support to the tile as an S1 version. This means that thinner or softer tiles may not withstand the malleable nature of the glue and a less than a firm backdrop.

Advantages of Tile Bond Adhesives

  • Quick and effective
  • Simple to use; simply combine with water
  • Increased bonding strength
  • It is possible to grout within 24 hours without waiting for the moisture to evaporate
  • Applicable to existing epoxy flooring as well as a variety of specific substrates such as polished cement, drywall systems, and so on
  • A thinner layer

Disadvantages of Tile Bond Adhesives

  • It takes time
  • The tiles must be wet
  • Moisture can collect behind tiles
  • Tiles may be readily unbended
  • It is impossible to place low absorbent tiles, such as 60×60 cm granite, or any greater sizes
  • It is not possible to put tiles over existing tiles or polished cement.
  • It is not possible to lay glass mosaics with this method.

How Do I Decide Which Tile Adhesive To Use?

Small ceramic tiles are frequently applicable for walls and splashbacks, and in most cases, a ready-mixed paste will suffice. A powdered adhesive is a mandatory requirement for affixing a larger ceramic tile (more than 30 × 30 cm) or any size porcelain tile to your walls.

What Amount Of Tile Glue Do I Require Per Square Metre?

Based on the formula of 1.8 kg per 1mm depth per m2, you will need to allow for a minimum 3mm bed of adhesive for bonding the XPS insulation boards or heat store boards to the sub-floor, 4mm cable coverage, and a minimum of 1.5mm bed of adhesive to bond the tiles (total depth of adhesive = 8.5mm).

How Much Water Should I Put In The Tile Adhesive?

If you have no prior experience dealing with adhesive and ceramic tiles, start with a modest amount of construction & building materials such as tile bond. As a result, pour around 1/4 gallon – 1 litre of water into a bucket to make a quantity of glue for three sq. feet per one-meter square.
