About this deal

Turn off under-floor heating. Test on an inconspicuous area first. Avoid using strong detergents to wash treated surfaces. On higher porosity materials, sufficient LTP Mattstone H20 should be applied wet-in-wet until treated surfaces are fully saturated. Do not use in temperatures under 5°C or over 25°C.

Installing Terracotta Tiles Installing Terracotta Tiles

The most important factor in achieving a good finish is to use a tiler with proven experience of laying and sealing terracotta tiles, as the wrong application of adhesive, sealers, grout and finishing products can ruin these beautiful tiles, costing you time and money. Apply the product generously and evenly to the face and edges of the tile and continue to saturate for 3-4 minutes moving the product continuously with the roller or brush to ensure complete coverage. Allow 2-4 hours between coats and apply a minimum of 3 coats to ensure a good seal before grouting. Ensure surface to be treated is completely clean, dry and free from dirt, grime, cement and grout. If necessary, first wash surfaces with a dilute solution of LTP Grimex, at 1:10. Rinse well to remove residues and leave to dry (24hrs).

Apply 2 coats of Ironwax Satin/Gloss with an hour between coats. Then allow 4 hours for the finish to cure before starting the grouting process using Ardex FL grout. If the tiler is not using our recommended Ardex FL grout, then please test your chosen grout on the surface of a sample tile, to ensure the grout can be cleaned away successfully. Once the Mattstone sealer has been allowed to fully cure (12 hours), apply 2 coats of Ironwax Satin/Gloss with an hour between coats. Then allow 4 hours for the finish to cure before starting the grouting process using Ardex FL grout. If the tiler is not using our recommended Ardex FL grout, then please test your chosen grout on the surface of a sample tile, to ensure the grout can be cleaned away successfully. In more recent times the opening up of travel to warmer climes in the 70’s piqued our interest in the material. No self-respecting conservatory extension of the 80’s seemed complete without a floor of Spanish terracotta. Routinely sweep the floor and wash with LTP Waxwash. Clean walls and work surfaces with LTP Stonewash Spray. Every 3 – 4 years surfaces may require more intensive cleaning in which case use LTP Grimex. Surfaces may require a top up coat of sealer after intensive cleaning. Refer to LTP Grimex technical data sheet for more information. After placing the tile on the adhesive, they can use their hands or a rubber hammer to level the tile surface. To cut the tiles, ideally they should use a water-cooled tile cutter, or if skilled enough they could use an angle grinder type cutter with the appropriate blade (i.e. unslotted and continuous). The suggested grout joint between the Handmade Terracotta tiles can vary from 5-8mm due to size tolerance and edge finish. On the Reclaimed Terracotta, these tiles feature an even higher size variation and will require a grout joint between 5-10mm to allow for this.

LTP Mattstone - Tiling Supplies Direct

LTP Mattstone H20 is a natural finish, water based impregnating sealer. It delicately enhances colour while helping protect against staining. LTP Mattstone H20 strongly repels water, oil and grease, and allows the surface to breathe. Apply generously and evenly using a paint brush or sponge. On highly absorbent surfaces apply further coats at hourly intervals until the surface is fully saturated. After 1 hour remove any excess sealer with an absorbent towel.

Recommended products

As above, the sealer can be applied to the tiles before they are laid, or at least 12 hours before grouting the tiles. Ensure you shake the bottle well and apply the product in accordance with the instructions on the bottle. Remember if using a roller, brush or cloth they must be appropriately washed out with white spirit and then disposed of carefully. Do not leave them exposed to direct sunlight, as if linseed is allowed to dry on a roller, brush or cloth, it can become self-combustible.
