Laying Guidelines For Reclaimed Terracotta & Brick Tiles

It is strongly recommended that our reclaimed terracotta and reclaimed brick tiles are laid
using a tile adhesive. Do not use a mortar mix unless you have some laying experience.

Sealing
The sealant should be applied after laying and prior to grouting. Allow the Sealant to fully
penetrate the surface. Any excess should be sponged off. Once the terracotta has been
sealed it should be left for at least 8 hours. Some sealants may take as long as 24 hours.
If Boiled Linseed Oil is to be applied, this must be done prior to sealing and left to fully
dry. Drying time – 24 hours.

General Precautions
All necessary movement joints such as the surrounds of baths etc. should either be initially
filled with suitable flexible mastic/silicone, or protected to ensure excess grout is not
allowed to accumulate and set.

When applying grout to reclaimed terracotta, ensure that an appropriate coating of sealant
has been applied before grouting to aid cleaning of the tile surfaces –
Always ensure that mixing containers and tools are clean and free of previous grout
mixes.

Always mix the grout with clean water free of contaminants such as salt etc.
Do not mix grouts of different types and manufacturers, and do not mix with cements
or limes etc.

Read the manufacturers instructions to ascertain the ‘pot life’ (working time) and bear
this in mind when mixing up a batch of grout.
Ensure that you are able to apply all the material mixed 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.

Preparing the grout
Whilst stirring pour the dry powder mix into a clean plastic bucket containing a small
quantity of clean water (refer to manufacturer’s instructions for details of quantities).

Mix until a smooth creamy paste is obtained. If available, use a slow speed mixer
(maximum 150 rev/mm) to prevent the excessive formation of air bubbles.

Leave the mix to stand for 2-3 minutes and then remix briefly before use.

The working time of the grout changes between different types and manufacturers, varying
from anything between 30 minutes to a few hours.

If the grout starts to set before applying it to the tiles, do not add more water, simply
discard and clean out the mixing container before making up another batch.

After completing your work, ensure that any material left is removed from your container,
and that the container is cleaned before the grout has cured.

Applying the grout
Always use the same method of working to obtain uniform results. Where the tiles are
absorbent or the ambient temperature is very high lightly dampen the surfaces of the joints
with a wet sponge before applying the grout. Fill the tile joints with the grout paste using
either a hard rubber float or squeegee without leaving voids or gaps.

Remove the 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 plastic.

Clean off the surplus grout with a damp hard cellulose sponge working diagonally across
the joints without applying any pressure. 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 and moistening new
ones.

Use a special grouting sponge – the proverbial bath and household sponges rapidly fall to
pieces and become quickly overloaded with grout.

The final cleaning of the residual film of grout powder from the surface of the tiles should
be carried out using dry waste paper or a clean dry cloth after the grout has set.

If the cleaning off is carried out too quickly (when the paste is still plastic) 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.

 

Seal again
It is now worth sealing the whole floor again to protect the grout and any areas that may
have been missed or not fully sealed.
