A rapid-setting tile adhesive for low-porosity tiles and substrates

About this product

weber.set rapid plus is a rapid-setting cement-based polymer-modified adhesive for fixing porcelain, ceramic, quarry, terrazzo and terracotta tiles, and brick slips, to rigid interior and exterior floors and walls.

It is available in grey and white.

Features and Benefits

- Manufactured under BSI Quality Assurance Scheme ISO 9001
- Polymer modified to provide a strong bond onto tiles with very low porosity
- For fixing onto low porosity substrates such as power floated concrete or existing ceramic or vinyl tiles
- Ready for light foot traffic and grouting after 2 hours
- Suitable for use in dry and wet conditions
- Specifically developed to allow easy bedding of large format tiles
- Very strong bond strength

Preparation

Ensure that all surfaces are clean, dry, sound and free from dust, grease or any contaminating barrier.

Make good any unsound areas and remove flaky or peeling layers before tiling.

Prime porous or dusty surfaces. weber PR370 is normally recommended for most walls in dry areas. weber AD250 is recommended for wet areas and floors. Allow the primer to dry.

Check before use that the colour of the adhesive does not cause staining or discolouration of light coloured or translucent tiles.

Mixing

Gradually add approximately 3.5 parts of powder to 1 part of clean water (measured by volume), and mix to a smooth, workable stiff paste. Normal usage requires 4.4 litres of water per 20 kg adhesive.

Use within 30 minutes of mixing.

Do not attempt to extend the pot life by adding more water to the mix.

Application

Do not use at temperatures below 5°C.
Apply the adhesive onto the substrate covering up to 1 m2 at a time (or no more than can be tiled within 10 minutes). Use a suitable notched trowel to achieve a bed thickness of 3 to 6 mm. Large or studded backed tiles may need to have adhesive buttered onto the tile back as well.

Bed the tiles firmly into the adhesive with a slight sliding and/or twisting action, to ensure a good contact. It is good practice to lift an occasional tile after fixing, to verify that the required contact is being achieved. In wet areas, external areas and all floors, the final adhesive bed should be free from voids.

Leave appropriate clearance joints for grouting and make any adjustments within 10 minutes.

Carefully clean off any excess adhesive from the tiles and joints with a damp cloth or sponge, before it sets.

Leave for at least 2 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 grouting, and then leave for a further 3 weeks before filling.

Brick and blockwork
Allow at least 6 weeks before tiling.
Lightweight blocks need priming with weber AD250. Ensure that the wall 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 weber PR370 or weber AD250, may be required if the surface is very dusty or

Concrete
Allow at least 7 weeks before tiling onto new concrete. Surface should be clean and free from laitance. Surface scabbling is recommended.

Existing ceramics/vinyl tiles
Ensure that the substrate is rigid and strong enough to take the weight of extra tiling, that the existing tiles are firmly adhered and that the surface is free from any wax, polish or detergent.

Plaster walls and anhydrite screeds
Leave plaster for at least 4 weeks before tiling. Ensure anhydrite screeds are fully dry (moisture content <0.5%). It is important that the surface is sealed by repeatedly coating with primer until the surface stops absorbing. For walls in dry areas use weber PR370 otherwise use weber AD250 or weber PR360.

Allowance for movement

Flexible joints should be incorporated to allow for slight movements due to changes in temperature, humidity etc. as indicated by BS5385:

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 (every 3 – 4.5 m on walls, 8 – 10 m on floors)

Contains cement.
