Isocrete CSA

Isocrete CSA . Cementitious Tile Adhesive 

Isocrete CSA is a high performance flexible cementitious adhesive mortar, ready to use with the addition of water, for bonding ceramic tiles using thin bed techniques.Isocrete CSA is used for bonding ceramic tiles with a continuous thin layer, up to10 mm thick. As it has high adhesion and flexibility, it can be used in situations where traditional tile adhesives are not suitable due to the type of tile or thesubstrate etc. Isocrete CSA can be used on walls and floors, in external or internal situations.

Advantages

It is suitable to bond the following types of tile: 

- Ceramic, extruded and earthenware tiles

- Low absorption ceramic tiles, which have poor adhesion to traditional tile adhesives

- Concrete and mortar

- Bricks

- Plaster 

- Plasterboard, fibre cement

 Surface Preparation

1. Surfaces must be solid/firm and free of dust, mould oil, grease, sealers, wax polish and organic growth. Organic growth must be removed and the spores killed with an effective fungicide such as a household bleaching solution.

2. Painted and Gypsum-plastered surfaces need to be chipped to remove 80% of the paint or Gypsum.Enamel-painted and bitumen surfaces: Strip all of the coating by scraping and then chip to expose 80% of the substrate 

3. Smooth, off-form/shutter or power-floated cement surfaces: Acid wash to remove laitance, rinse well with cold clean water.

 

Mixing

  1. Gradually mix 25kg of Isocrete CSA Tile Adhesive to ± 6 litres of clean cold water or 5kg of Isocrete CSA Tile Adhesive to approximately 1,50 litres of clean water. 
  2.  Mix to a creamy smooth paste. Mechanical mixing will result in a lump free, easier to use mix.
  3.  Allow mix to activate for 5 minutes.
  4.  Remix product before use. DO NOT ADD MORE WATER
  5.  Do not mix more adhesive than can be used within ± 1 hour.

Application

 1. Spread enough adhesive with a notched Wall or Floor trowel to a minimum bedded thickness of: ● 3mm for wall tiling and 6mm for floor tiling. ● Heavily lugged, grooved or dovetailed tiles must be but- tered to fill any voids with adhesive before placing into wet adhesive.

2. Press tiles firmly into wet adhesive with a twisting action. Use a rubber mallet to bed large or heavy tiles.

3. Occasionally lift a tile to check that full contact is being made between the tile and the wet adhesive. ● Remove excess adhesive from joints and tiled surface before drying has occurred.

4.Minium routing joints for walls is 2mm and for floors 3mm or as recommended by the tile manufacturer. ● Do not butt joint tiles

5. Tiles must be allowed to dry for a minimum of 24 hours before grouting takes place. (For sealed or nonporous surfaces allow minimum 48 hours.)

 

PRECAUTIONS ● Wear rubber gloves. ● Do not ingest. ● In the event of contamination rinse thoroughly with cold water. ● Use as directed. ● Use a dust mask. ● Work in well ventilated areas. ● Seek medical assistance if irritation or discomfort persists
