Use a waterproof, floor tile adhesive which allows slight
flexibility when set. Follow the manufacturer's instructions
and using a notched or plain trowel, as directed, to spread
the adhesive on the floor to cover a manageable area for
laying a sheet of tiles. Press the sheet into the desired
position. It is very important to lay the first sheet correctly,
as its position will determine the position of all the other
tiles in the room.
Use a batten nailed to the floor to give a straight edge
to guide the positioning of the tiles. Remember to use spacers
between the sheets to match the spacing between the individual
tiles. These areas will be grouted when the floor is complete
and must be equally spaced for neat, accurate results.
Use a spirit level to check the horizontal level and a
straight edge to continually check the position of the sheets
on the floor. Continue across the room and work towards
the door. Leave for as long as possible (24 hours) before
removing the battens and using individual tiles around the
border. If a sheet needs to be laid around an object, discard
individual tiles as close to the structure as possible.
Fit the sheet and cut and replace any pieces required,
remembering to use spacers around the individual tiles.
Leave the floor to set for 24 hours. Remove the spacers
and use warm water to peel off the facing of the sheets.
The floor is now ready for grouting.
Waterproof floor grout is available in a variety of colours,
but the standard colours are white, grey or brown. If you
are unsure of the colour to use, mix pigments of colours
with dry powdered grout and attempt to match the colour
before adding the water. However most floor tiles are grouted
with a mortar mix. Use a plastic scraper or a rubber-bladed
squeegee to push the grout between the gaps in the tiles.
Make sure all the spaces are evenly filled and then wipe
the grout off the tile surface before it dries.
Use a blunt edge of a stick or tool carefully, to smooth
the surface of the grout in the gaps - but do not 'dig down'
into the grout. Remove any excess grout before it dries.
Allow the floor to dry completely before polishing the
surface of the tiles with a dry cloth.
