Tiles (7) are laid on a base (1) by (i) unrolling a meltable strip (2) onto the base (1) while simultaneously heating the underside (3) of the strip (2); (ii) unrolling further strips (2) such that they lie edge to edge with each other; (iii) pressing the softened strips (2) onto the base (1); (iv) unrolling a second layer of strips (4) on top of the first layer (2) while simultaneously heating both the contacting faces (5) and prssing together; (v) heating small areas of the upper surface (8) of the second layer (4) of strips until liq.; (vi) laying individual tiles (7) onto the fluid surface of the upper layer (4); (vii) filling in joints between tiles (7) with mineral or plastic basid mortar. Strips (2,4) are pref. bsed on bitumen or plastic, and are approx. 5mm thick and protected on at least the underside with a meltable or combustible film. Lower strips (2) have a polyester reinforcement positioned on third of the strip (2) thickness from the base. USE/ADVANTAGE - For applying tiles to a floor e.g. stone, floorboards or a base already covered in tiles. Does not require the use of a separate adhesive and prevents water penetration through to the base.
