For the perfect finish, it’s a must to spend as much time on your choice of grout as you do on your choice of tiles
Grout is generally a mixture of cement, sand and water. It is much finer than cement alone and is ideal for filling voids and sealing joints. Like most building materials, grout not only needs to look good, but it needs to be robust, abrasion resistant, durable and most importantly, suitable for the specific needs of the job in hand.
Before making any decisions, consider the following factors:
Tile type: Porcelain, natural stone, composite etc.
Surface to be tiled: Dry or wet areas.
Size of tile joint: How wide a gap is the grout recommended for? How smooth is the finish? Floor tiles have wider gaps than those used on walls.
Application: Outdoors or indoors. e.g. if used in bathrooms/kitchens, steam and water need to be taken into account.
Features: Specific requirements for anti-bacterial qualities, chemical resistant, or sterile conditions.
Colour: The difficulty of matching grout for both floor and wall tiling in the same area
Drying time: Some grout may take longer to dry than others. A good floor grout will need between two to three hours to dry before it will bear light traffic.
The right choice of grout will give you the best chance of a consistent colour tone and smooth, durable finish and will also help you to avoid slumping, shrinking and cracking. Always check the versatility of any product before making a decision.
