Fitting Outdoor Tiles
As with indoor tiles it is important to plan and prepare the areas sufficiently and measure accurately.
Prepare the Surface
The surface which you are tiling must be cured, stable and level.
Curing - Concrete must be mature and fully cured which will be typically 6-8 weeks after installation in good drying conditions. Bonded sand cement screeds typically 4-6 weeks to cure.
Smoothing & Leveling - The surface may require smoothing and leveling to ensure it is adequately prepared for tiles to be fitted. Ardex K301 is designed for external smoothing, leveling or resurfacing of exterior concrete areas including damaged drives, paths, patios, and parking areas. Ardex K301 can be applied from 2 -20mm thick depending on the surface requirements. Gradients and falls must be installed to avoid water pooling on the surface of the tiles.
Primer - Ardex P51 primer is a concentrated water based primer and bonding agent - this is recommended to improve the bond between the adhesive and the substrate.
Adhesive - BAL Pourable One is a rapid setting flexible adhesive which is suitable for most large tile types for both interior and exterior use. It can be used for a 2- 25mm bed depth so is suitable for use to level uneven surfaces. The installation will be suitable to grout after 3 hours. The gaps between the tiles must be filled with a cement based grout such as BAL cement based grout. Expansion joints are required and we would suggest Mortec Soft Joint, an elastic, neutral curing silicon based cement like joint filler.
Raised Pedestal System
Terra Maxx Pedestal System has pre-assembled pedestals which enable quick and easy laying of tiles on exterior surfaces. Water runs between the tile joints and gullies can be hidden in the cavity between the tile covering and the substrate. The tiles can be lifted and the surface underneath can remain accessible.
