A high-performance ready-mixed ceramic wall tile adhesive for interior use where wetting or limited movement is expected

Product Features

About this Product

weberfix WR plus is a high-performance non-slip acrylic, ready-mixed ceramic wall tile adhesive.

It is recommended for interior use, particularly in areas where limited movement/vibration is expected or improved resistance to water is required.

Can also be used to fix insulating materials such as expanded polystyrene.

Features and Benefits

  • Manufactured under BSI Quality Assurance Scheme ISO 9001
  • Non-slip/easy to use
  • Low colour formulation
  • Very high initial grab
  • Increased water resistance for intermittently wet conditions
  • Flexibility to absorb limited movement or vibration
  • Priming not required
  • Suitable for porcelain tiles (on porous surfaces)


Not suitable for floors, exterior use, or pools.

Not suitable for fixing non-porous tiles onto non-porous substrates.

In heavy use communal showers/wet areas, a cement-based adhesive is recommended.

Preparation & Application


Ensure that all surfaces are clean, dry sound, free from grease, dust or any other contaminating barrier, and capable of supporting the weight of tiling.

Make good any unsound areas before tiling. Remove flaking or peeling layers.


Do not use at temperatures below 5°C.
Spread the adhesive onto the wall, rather than onto the tiles, using a suitable notched trowel. Do not spread an area larger than can be tiled in approximately 30 minutes. Larger or studded-backed tiles may also need to be buttered with adhesive.

Fix the tiles within 30 minutes of applying adhesive (less at elevated temperatures). If lightly pressed, the adhesive should still stick to the fingers. If not, then it should be removed and more applied. Firmly press the tiles into the adhesive bed, with a twisting or sliding action, leaving at least 2 mm gaps for grout joints.

For dry areas, the contact area between the adhesive and tile must be at least 70%, uniformly over the whole tile. In intermittently wet areas, it is essential that there are no voids under the tiles. The final bed thickness should be no more than 3 mm.

It is good practice to occasionally remove a tile to check that the required contact is being achieved.

Remove any excess adhesive from the tiles and joints before it sets and remove any tile spacers after approx. 1 hour.

Ready-mixed adhesives gain strength on drying, so leave for a minimum of 24 hours, before grouting. On non-porous surfaces, leave for at least 3 days. These times should be extended in poor drying conditions such as when using larger tiles or tiling at low temperatures.

For wet areas, particularly commercial or power showers, an appropriate grout should be used to minimize water penetration. Leave for 2 weeks after grouting, before using the shower.

Tile onto a plaster finish coat. Leave new plaster for at least 4 weeks so that it will be strong enough to support the tiling weight. Plaster can support 20 kg of tiling per m2.

Securely fix and brace all boards to ensure stability. They should be screwed, not nailed, at 300 mm centres horizontally and vertically. Plasterboard can support 32 kg of tiling per m2.

Cement/sand render
Leave new surfaces to dry for at least 2 weeks before tiling.

Leave new surfaces to dry for 6 weeks before tiling. Ensure that the surface is sufficiently flat. Lightweight blocks must be primed and are not suitable for very large tiles.

Plywood/fibre-particleboard/fibre reinforced cement sheets
Securely fix and brace all sheets and boards to ensure stability. They should be screwed (not nailed) at 300 mm centres horizontally and vertically. Preferably, use exterior grade plywood and prime the front and reverse faces and edges with weber AD250 to prevent distortion. Avoid very large tiles.

Existing ceramic tiling/paint
The surface should be clean, dry, sound and capable of supporting the expected loads. Any unsound areas should be removed and made good. Existing tiles must be firmly adhered. Existing paint should be resistant to water (e.g. not emulsion), lightly abraded on the surface and then any dust removed before tiling. Drying times will be significantly extended, therefore fixing large tiles is not advised.

Allowance for movement
Flexible joints should be incorporated to allow for slight movements due to changes in temperature, humidity etc. as indicated by BS 5385:

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)
