Preparation
All surfaces should be clean, dry, dust free, sound and free from grease or any other contaminating barrier, unsound areas should be made good before tiling. Flaky or peeling layers should be removed. Porous or dusty Surfaces should be primed using a suitable primer and allowed to dry before tiling; acrylic primer is recommended for areas likely to become wet and floors.
Mixing Instructions
Gradually add approximately 4 kg powder to 1 kg clean water (Measured by volume), and mix to a smooth, workable, stiff paste.Do not attempt to extend the pot life by adding more water.
Instructions for Use
Do not use if temperature is below, or likely to fall below, 5 C°, apply the adhesive onto the substrate using a suitable notched trowel, Covering up to 1m² at a time (or no more than can be tiled within 10 minutes). Tiles with studded backs may also need buttering with adhesive. The tiles should be firmly bedded with a twisting or sliding action, leaving clearance joints for grouting, it’s a good practice to occasionally remove a tile to ensure that the appropriate contact is being achieved.
On interior walls, in areas not subject to wetting, the adhesive should contact at least 70% of the tile back on walls subject to wetting, exterior situations and all floors, the adhesive bed should be free from voids, adjustments can be made for up to 10 minutes, clean excess adhesive from tiles and joints with a damp cloth before it set. Adjustments can be made for up to 10 minutes, clean excess adhesive from Tiles and joints with a damp cloth before it set.
Leave for at least 24 hours before grouting, longer is required at lower Temperatures or when tiling onto impervious or sealed surfaces. For Swimming pools, leave at least 3 days before grout-ing, and then leave for a Further 3 weeks before filling.
| SURFACE | APPLICATION NOTES |
|---|---|
| Brick and block work | Allow at least 6 weeks before tiling. Light weight blocks need priming with PVA. Ensure that the walls face is sufficiently flat. |
| Cement/sand render Or screed | Allow at least 3 weeks for screed and 2 weeks for render before tiling. Priming with PVA may be required if the surface is very dusty. |
| Concrete | Allow at least 7 weeks before tiling onto new concrete. Surface should be clean and free from laitance. Surface scrabbling is recommended. |
| Existing Ceramics / Vinyl Tiles | Ensure that the substrate is strong enough to take the weight of extra tiling, and that the surface is free from wax or polish, lightly abrade surface to improve key. |
| Plaster walls & Anhydrite screeds | Leave plaster for at least 4 weeks before tiling. Anhydrite screeds must be fully dry and any laitance removed. It is important that the surface is sealed by repeatedly Coating with primer until the surface stops absorbing - for walls in dry areas use PVA. |
Allowing for movement:
Flexible joints should be incorporated to allow for slight movements due to changes in temperature, humidity, etc.
a) Where the tiling meets other materials (e.g. Floor perimeters)
b) Along all internal corners-vertically and horizontally
c) Over existing movement joints or changes in background material
d) dividing large tiled areas into bays (even 3-4.5m on walls, 8-10m on Floors)
Fire:
TECHNOFIX POOLS is non flammable.
Cautions:
TECHNOFIX POOLS may cause irritation to skin or eyes, because it contains Portland cement and sand.
Storage:
Shelf life is 12 months @ 2 C° – 40 C° in dry and shaded area.
