1. Tile joints are to be grouted with an appropriate tile grout that complies with the Australian Standards AS: 4992.3-2006. It is imperative that the manufacturer’s recommendations for grouting wall or floor tiles are strictly followed.
2. Proprietary manufactured grouts mixed and applied as per the manufacturer’s recommendations will provide batch consistency, uniformity of colour, texture and its long term integrity within the tiling system.
3. Proprietary grouts are suitable for interior and exterior applications within residential and commercial situations. They are suitable for dry areas & wet areas and fully submerged situations.
4. Proprietary, grouts are robust enough to take the typical topside load of foot-traffic and light maintenance vehicles
5. Proprietary grouts can be polymer modified, homogenous, and consistent in colour and colour fast, workable, easy to apply, yet dry quickly, with optimum resistance to abrasion including flexural strength/compression with resistance to freeze/thaw cycles and some acids with low pH levels.
6. AS-4992.3-2006 classification for grouts ensures that appropriate, specific manufactured grouts for the many different tiling systems & situations are available for grouting tile joints.
7. The use of anti-efflorescence grouts should be considered where water/moisture may likely migrate and activate chlorides (salts) within the tiling system.
8. Tile joints may vary in width and some proprietary grouts may also be suitable for tile joints from a minimum of 1.5mm and up to 20 mm.
9. Tile edge/grout joint cracking of the tiles after installation will be less likely to occur if all spacers and any excess adhesive/cement mortar, dirt, grime is removed before grouting the tile joints. Particularly for tile joints within large floor or wall tiled areas.
10. Some grouts may also fade in colour when subject to continuous strong sunlight and or in high foot traffic situations which require mechanical cleaning, particularly if solvents or abrasive cleaning agents are used within the cleaning process. Advice from the tile grout manufacturer should be requested for a suitable grout for the above type of situations.
11. Some grouts may shrink and present fine cracking alongside metal abutments, such as door & window frames, door floor angles & metal movement joints. To minimise the likely hood of cracking, seek advice from the tile grout manufacturer for a suitable non/low-shrinkage rate grout or an alternative joint filler such as silicon.
