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.
