Laying Guidelines for Reclaimed Terracotta and Brick Tiles
If laying on a new screed, under-floor heating or board, a flexible floor tile adhesive should be used.
If laying on an old screed a tile adhesive or a mortar mix may be used but we strongly recommend an adhesive unless experience has been previously gained in this area.
When laying any floor it is highly recommended to measure carefully and to dry lay (lay down a couple of square metres) in the desired pattern and make sure that this is not only something that is desired and in keeping with the style of the property but it is also something that is practical and within your capabilities. Only then, start to actually lay the floor, keeping the area as clean and dust free as possible. If any adhesive or mortar spills on to the upper surface of the tile, clean away with a damp sponge as soon as possible.
The sealant should be applied either by spray or by brush after the floor has been laid but prior to grouting. Allow the Sealant to fully penetrate the surface. Any excess sealant should be sponged off. Once the tile has been sealed it should be left for at least 8 hours (overnight will suffice). Some sealants may take as long as 24 hours. We strongly recommend our GoProtect range of sealants to avoid any issues. See – Sealers & Cleaners
- Make sure that any flexible joints are either filled with silicone/mastic.
- Ensure that a suitable coating of sealant has been applied before grouting.
- Ensure that all equipment is clean and free of impurities.
- Use clean water, free of contaminants.
- Do not mix grouts of different types or from different manufacturers.
- Do not mix with cements or limes etc.
- Always read the manufacturer’s instructions before mixing any grouts or adhesives.
- Ensure that all materials are used prior to the pot life being exceeded.
- Preparing the joints – The joints to be grouted must be dry, clean and free of dust and foreign matter. They should be clear for at least 2/3 of the depth of the tile – any excess mortar or adhesive must be removed.
Applying the grout
Always use the same method of working to obtain uniform results. Either point the tiles or float the grout across. If sealed correctly the tiles should not be. Fill the tile joints with the grout paste using either a hard rubber float or squeegee without leaving voids or gaps. It is important to work the grout into the joints, ensuring there are no air bubbles.
Remove any excess grout from the surface by drawing the float diagonally across the joints whilst the paste is still fresh.
Leave the paste to firm up in the joints until it is no longer liquid. A dusting should appear on the surface of the tiles
Clean off any surplus grout with a damp hard cellulose sponge working diagonally across the joints without applying any pressure, ensuring that the sponge does not penetrate the joint. Rinse the sponge frequently preferably using two or three buckets of water; one for removing the surplus paste from the sponge and the other one or two for just clean water for the final rinsing of the sponge.
Use a special grouting sponge – Bath or household sponges rapidly fall to pieces and become quickly overloaded with grout.
If the cleaning off is carried out too soon after application (when the paste is still liquid) it is possible that the grout will be partially removed from the joints.
On the other hand, once the product has set hard, cleaning by mechanical means will be necessary which is very difficult and likely to cause damage to the surfaces.
It is now advisable to seal the whole floor again to protect the grout and any areas that may have been missed or not fully sealed.
