MUDD FAST FIXER extended information:

Coverage:  Depends on the nature and flatness of the surface and the method of application, but on a level background the approx.. amount of adhesive required will be: approx. 2kg/m2 for dry wall areas. approx. 4kg/m2 for floors, exterior and wet areas.

The surface to be tiled should be level, clean and free from dust, grease or any loose flaking material.
Allow new walls to dry out for minimum 6 weeks before rendering/plastering/tiling. Direct fixing of tiles to clay brick/medium density concrete is acceptable if surface is sufficiently flat.

Suitable surfaces include:
Calcium Sulfate-based screeds ie. Anhydrite: Ensure they have been laid and prepared in accordance with the screed manufacturers recommendations. Generally they require sanding and must have a moisture content of less than 0.5% (measured using the carbide method). Prime the screed with 2 coats of MUDD PRIME TIME. The first coat diluted 1 part prime to 1 part water by volume, followed by a second coat at 90 degrees to the first coat undiluted. Allow to dry in between coats and the second coat should also be touch dry. Tiling must commence within 24 hours.

Existing glazed ceramic tiles/glazed bricks
Ensure existing tiles/bricks are soundly bonded to a stable background that is sufficiently strong to support the weight of the new tiling. Mix MUDD FAST FIXER with MUDD THE STRENGTHENER (diluted 1:1 by volume with water) If areas of tiles/bricks are loose or hollow-sounding, remove and make good.

Must be at least 4 weeks old before tiling. Ensure finish coat has been applied, and surface is free from dust, efflorescence and friable material. If plaster is shiny or polished, brush thoroughly before priming with MUDD PRIME TIME (undiluted) and allow primer to dry.
If plaster is defective/badly cracked, cut back to straight vertical or horizontal edges. Dry brush the background and make good with a suitable non-shrinking filler and prime as above.

Ensure boards are securely fixed and rigid at 300mm centres vertically and horizontally or as per board manufacturer’s recommendations with no protruding fixings. Ensure the face intended to receive decorative finish is exposed.

Asphalt (suitable grade e.g. flooring)
Must be of a suitable grade, be clean, in sound condition (without brittleness, softening. etc.) and have adequate cohesive strength, a natural float finish and laid on a firm rigid base. Ensure that surface is sufficiently regular to suit bedding depths of adhesive. Clean thoroughly to remove surface dirt using warm water and a suitable detergent. Remove all detergent residues with clean water.

Concrete; cement: sand screeds and rendering

Before tiling, allow the following minimum drying times:

  1. Concrete/concrete block walls/clay brickwork: 6 weeks
  2. Cement:sand screed: 3 weeks
  3. Cement:sand rendering: 2 weeks (3 weeks for swimming pools)

Existing unglazed ceramic tiles, quarry tiles, terrazzo and natural stone

Ensure existing tiles are soundly bonded to a stable background that is sufficiently strong support the weight of the new tiling. If areas are loose or hollow-sounding, cut out and make good.

Fibre reinforced cement boards and lightweight tile backing boards for floors

Check suitability with board manufacturer. Ensure boards are (i) sufficiently rigid and stable to receive tiles; (ii) can carry the additional load without excessive deflection; and (iii) has adequate ventilation under the boards.

Overlaid timber floors (min. 15mm)
Ensure timber floor (i) is sufficiently rigid and stable to receive tiles; (ii) can carry the additional load without excessive deflection; and (iii) has adequate ventilation under the timber. Overlay existing timber floor with water resistant plywood, minimum. 15mm thick, screwed (not nailed) at 300mm centres. Prime all timber surfaces on back face and edges and the face to be tiled with neat MUDD PRIME TIME. Allow to dry.

Existing vinyl tiles

Ensure these are in good sound condition and securely bonded to their base. Remove loose or damaged tiles/areas of sheet along with any loose or soft adhesive. Remove any polishes, wax, grease etc. with a suitable proprietary cleaner. Prime with 2 coats of undiluted MUDD PRIME TIME.

NOTE: Cushioned types of flooring are not suitable and must be completely removed along with the adhesive residue prior to tiling.

Underfloor heating: – once the screed is dry it must be heated slowly at a rate not exceeding 5°C per 24 hours to the maximum operating temperature or 25°C and maintained at that level for 3 days, before being allowed to cool to room temperature. The heating must be turned off before tiling. Once completed ensure that a minimum of 14 days have elapsed before the floor is brought back to its operating temperature at a maximum rate of 5°C per day.

Mix in the ratio of approx. 3 parts powder to 1 part water by volume. Add the powder to clean water and mix thoroughly until a smooth uniform consistency is obtained. Use within 45 minutes of mixing (at room temperature). Do not use below 5°C.


  1. Spread the adhesive with a suitable notched trowel to cover approximately 1m2 or an area that can be tiled in 15-20 minutes working time.
  2. For floor tiling, wet areas and exterior situations, a solid-bed trowel must be used.
  3. Press the dry tiles firmly into the adhesive, checking periodically that good contact is maintained with the backs of the tiles. Tiles should be fixed within approx. 15-20 minutes of adhesive being applied, depending on the porosity of the surface and the atmospheric conditions (check the adhesive ribs periodically and if a skin has formed, remove the adhesive and apply a new layer). Tiles can be adjusted up to 10 minutes after initial positioning.
  4. Leave 1-2mm joints between wall tiles and minimum 3mm joints between floor tiles.
  5. Remove all surplus adhesive with a damp cloth before it sets.


MUDD FAST FIXER is fully resistant to water, however, being cement-based it is not impervious to the passage of water. To improve protection on water- sensitive backgrounds, apply a tanking membrane such as MUDD DAM IT to the background or use an impervious grout in the joint between tiles.


Grouting can be carried out after a minimum of 3 hours with MUDD GROUT WITH CLOUT flexible floor and wall grout.


This product must be stored in unopened packaging, clear of the ground in cool dry conditions and protected from excessive draught. Store in dry conditions, between 5°C and 30°C. Ensure pert-used bags are resealed. If stored correctly the shelf life of this product is 12 months.
