Tile Fixing Techniques 

The adhesive is applied to the prepared 

surface with a trowel and then combed 

through with a suitably sized notched 

trowel in straight ribs to give a ribbed 

mortar bed. The tiles should be fixed 

within the open time of the applied 

adhesive and pressed into place with a 

twisting and sliding action to achieve the 

required contact. 

For tiling to walls in dry internal locations 

the adhesive contact should be at least 

50% of the back of the tile. 

When tiling to floors and all external 

locations, or in wet areas such as showers 

and swimming pools, solid bed fixing 

should be achieved. To achieve a solid 

bed usually requires the tiles to be 

buttered immediately prior to placing into 

the ribbed bed so no voids are left 

beneath the tiles.* 

Tile Grouting Technique with 

Cement-Based Grout 

Using a rubber squeegee work the 

cement-based mortar into the tile joints 

ensuring they are completely filled, deep 

joints can usually be filled in one 

operation without the grout sagging in the 

joints. When the mortar firms up in the 

joints this allows for washing down to 

produce a virtually flush finish, with a 

smooth surface by using just a wet 

sponge. 

Tile Fixing and Grouting Techniques 

The size of notched trowel chosen 

depends on the tile size, the surface 

being tiled, the profile on the back of the 

tile and the degree of coverage required. 

If an area is left with dried residue on the 

tile face prior to cleaning, the grout 

residues may, within the working time of 

the grout mortar, require moistening in 

order to make washing off easier. 

*When fixing floor tiles, pourable adhesive 

can be used if preferred to enable solid 

bedding of the tiles without the need to 

butter the backs of the tiles. 

For Natural Stone fixing - see page 9. 

Any dry film remaining on the tile face 

after cleaning down can be easily 

removed by using a damp sponge once 

the mortar has hardened in the joints.

Tile Fixing and Grouting Techniques 

Tile Grouting Technique 

with ARDEX WA Epoxy- 

Based Grout 

1. First, ensure that you are ready with 

the correct tools and sufficient materials. 

Ensure that you have protective gloves, 

ample fresh water and have read the 

precautions on the containers. 

Add the complete contents of the 

hardener container into the container of 

resin. Mix the resin and hardener together 

then transfer some of the mix back to the 

hardener container, mix in the hardener 

container to disperse any hardener not 

transferred initially. Transfer this material 

back to the resin container then 

thoroughly mix the hardener and resin 

together until a uniform mortar is 

produced. Mixing should be carried out 

using the propeller type stirrer with a slow 

speed drill which will make mixing easier 

and faster. When mixed, the mortar 

should be removed from the container 

and spread out onto the wall or floor tiles 

or an impervious surface e.g. metal plate, 

to ensure the maximum working time of 

the mortar by preventing self-heating in 

the container. 

2. Work the mortar into the dry joints 

immediately after mixing, using a suitable 

rubber backed squeegee, ensuring that 

the joints are completely filled. 

N.B. Some porous and matt finished tiles 

are prone to surface absorption of epoxy 

resin. To avoid shading variations apply 

the mortar over the entire tile surface. 

3. The use of a good rubber backed 

trowel/squeegee removes virtually all 

surplus material from the surface of the 

tiles and will make cleaning easier. 

4. Mist spray 

onto the wall tile 

surface prior to 

emulsifying the 

grout residues. 

5. Cleaning the 

residues from the surface of the tiles 

should proceed as soon after the 

application as possible. Use a 

Scotchbrite ® pad and a little water, 

working in circular movements to emulsify 

the residues on the tile surface whilst 

applying gentle pressure. Blue pads 

should be used for cleaning ARDEX WA 

grey and white pads for ARDEX WA white. 

N.B. If the Scotchbrite ® pad is pressed 

too hard onto the tiled surface, more 

mortar will be removed from the joints. 

Take care to ensure that empty joints are 

kept dry and not accidentally filled with 

emulsified material. 

6. Smooth the joint surface by gently 

wiping along the joint surface with a moist 

sponge to obtain a satisfactory finish. 

Carefully remove the emulsified material 

from the surface of the tiles with a 

squeezed out sponge, wiping with each 

face once before rinsing again in clear 

water. Water should be changed on a 

regular basis. A square cut sponge wiped 

diagonally across the surface of the tiles 

will leave the joints as flush as possible. 

Slowly wipe across to allow the sponge 

time to absorb the slurry as it passes over 

the tiled surface. 

7. Note: Once the cleaning has been 

completed, the joints should be allowed to 

harden sufficiently before a final clean 

down to remove any residual film which 

may remain after wiping with a sponge. 

The use of a Scotchbrite ® pad and water 

will remove this film, this final cleaning 

should be carried out within 24 hours of 

application.

Finish

Movement Joints 

The incorporation of movement joints is an important 

part of a ceramic floor or wall tiling project and should 

be detailed at the commencement of work. Movement 

joints are incorporated to accommodate moisture or 

thermal movement and drying shrinkage of the 

background or substrate to be tiled. Detailed advice is 

given in the relevant sections of BS 5385 parts 1, 2 

and 3, extracts of which are given here. 

Internal Wall Tiling BS 5385-1 : 

1995 3.5 Movement Joints 

3.5.1 – General 

"Consideration should be given at the design stage to 

the provision of movement joints. The type and location 

of movement joints involve considerations of 

construction materials, bedding systems, anticipated 

temperature and humidity conditions, areas concerned 

and the setting out of the tiling. 

Stresses occur in the tiled installation as a result of 

movement due to such factors as drying shrinkage and 

moisture and thermal changes. These stresses can 

sometimes cause loss of adhesion, bulging or cracking 

of the tiling, but can be localised by incorporating 

movement joints. 

Where the background is mature and stable, e.g. 

existing rendering or plaster, the movement joints in the 

tiling, which are not to be confused with structural 

movement joints, may need to extend only through the 

tiling and its bed, and should be a minimum of 6mm 

wide. 

Materials for movement joints should conform to 2.10. 

3.5.2 – Location 

Movement joints should be located in the tiled 

installation to coincide and be continuous with all 

existing structural movement joints, although they will 

actually be formed as separate joints isolated by 

suitable thicknesses of back-up material. 

In detailing the location of movement joints in tiling the 

designer will normally specify that they are positioned 

in the following locations. 

a) over existing and/or structural movement joints; 

b) where tiling abuts other materials; 

c) where tiling is continuous across junctions of 

different background materials; 

d) in large tiled areas, at internal vertical corners 

and at 3m to 4.5m centres horizontally and 

vertically; 

e) where stresses are likely to be concentrated, for 

example at changes of alignment. 

Where large degrees of thermal movement or vibration 

are expected, the frequency of movement joints should 

be increased to accommodate the movement. 

Movement joints in the tiling should be of a suitable 

width to permit the sealant to accommodate the 

expected structural movement. 

Conversely, in small tiled areas in normal conditions, 

intermediate joints should not be necessary on walls up 

to 6m long provided the background is strong and 

dimensionally stable, there is adequate compressible 

joint width around each tile and movement joints are 

included at internal angles." 

External Wall Tiling BS 5385-2 : 

1991 20 Movement Joints 

20.1 – General 

"Consideration should be given at the design stage to 

the provision of movement joints. The type and location 

of movement joints are influenced by considerations of 

construction, materials, bedding systems, anticipated 

temperature and humidity conditions, areas involved 

and the setting out of the tiling. 

Stresses occur in the tiled installation as a result of 

movement due to such factors as drying shrinkage and 

moisture, thermal changes and creep and can 

sometimes cause loss of adhesion, bulging or cracking 

of the tiling, but these stresses can be localised by 

incorporating movement joints. 

Material for movement joints should be in accordance 

with clause 13. 

20.2 – Location 

Movement joints should be located in the tiled 

installation to coincide and be continuous with all 

existing structural movement joints, although they will 

actually be isolated by suitable thicknesses of back-up 

material. 

Where tiles are fixed to an intermediate substrate, the 

movement joint should extend through the intermediate 

substrate. 

Where backgrounds are mature and stable, the 

movement joints in the tiling, which are not to be 

confused with structural movement joints, should 

extend only through the tiling and its bed, and should 

be a minimum of 6mm wide. 

20.3 – Disposition and Forming 

In detailing the disposition of movement joints, the 

designer should consider the following locations in 

relation to their effect on setting out the tiling: 

a) over existing and/or structural movement joints; 

b) where tiling abuts other materials; 

c) at junctions between different background 

materials, where tiling is continuous across them; 

d) at storey heights horizontally and approximately 

3m to 4.5m apart vertically; ideally, they should 

be located over movement joints in the structural 

background and at structural material changes; 

for example, horizontal joint at top and bottom of 

Movement Joints 

floor slab, vertical joint at internal corners and at 

junctions with columns; 

e) at external angles, vertically between 0.25m and 

1m from the angle and symmetrically wherever 

possible. 

Where movement joints in tiling occur over movement 

joints in the background, they should coincide and be 

continuous with these joints and should be of a 

suitable width to permit the sealant to accommodate 

the expected movement." 

Interior and Exterior Floor Tiling BS 

5385-3 : 1989 Clause 19.1.1 gives 

the following guidance 

"Stresses may result from factors such as drying 

shrinkage, deflection and moisture movements in the 

base and thermal and moisture changes affecting the 

flooring. These stresses can sometimes cause loss of 

adhesion and bulging or cracking of the flooring. To 

counteract this, movement joints extending through the 

tiling and its bed should be incorporated in the 

installation. 

The building designer should assess the magnitude of 

any stresses and decide where movement joints, 

flexible joints and contraction joints should be located, 

having regard to all the relevant factors including the 

type of flooring and bed." 

Detailed guidance as to the different types of 

movement joints is available in BS 5385 Part 3:1989 

Clause 19, details as to where joints should be sited 

are contained in Clauses 23.6.2, 23.6.3 and 23.6.4. 

In general, movement joints should be sited over 

existing movement joints and/or contraction joints in 

the base. They should be continuous with the base 

joints and of sufficient width to allow the joint filling to 

accommodate the expected movement. 

Movement joints should be inserted where the tiling 

abuts restraining surfaces such as perimeter walls, 

columns, curbs, steps and plant fixed to the base. In 

floors with dimensions of 2m or less between 

restraining surfaces, perimeter joints are not necessary 

unless the conditions that may generate stresses are 

likely to be extreme. 

Intermediate joints may also be necessary depending 

on the dimensions of the floor, for floors other than of 

suspended construction no intermediate joints are 

normally necessary if the distance between perimeter 

joints is less than 10m. Intermediate joint spacing is 

generally at 8-10m intervals, detailed guidance is given 

in Clause 23.6.4 of BS 5385-3:1989.

Internal Floors 

CEMENT/SAND SCREED 

New cement and sand screeds require at least 3 weeks drying time prior 

to fixing tiles.* 

ANHYDRITE SCREED 1 

Ensure that the surface has been prepared in accordance with the 

manufacturers instructions and is free of dust, is hard and the anhydrite 

screed is fully dry. Use ARDEX P 51 primer diluted 1:3 by volume with 

water. 

HARD FLOORING GRADE ASPHALT SANDED 2 

With well adhered sand key no primer is required. If sand key 

is poor or worn off, proceed as for smooth asphalt. 

HARD FLOORING GRADE ASPHALT SMOOTH 

Use ARDEX P 82 primer. 

EXISTING CERAMIC TILING 

Ensure existing tiling is well adhered. Thorough cleaning and rinsing off 

essential. 

TERRAZZO 

Ensure existing terrazzo is well adhered. Thorough cleaning and rinsing off 

essential; mechanical preparation may be required. 

CONCRETE 

Ensure that new concrete is at least 6 weeks old prior to tiling. 

Check that surface curing agents are removed. 

WET LOCATIONS 3 

Backgrounds should be water resistant and suitable for direct fixing. Tiles 

should be solid bed fixed. 

TIMBER FLOORS 

Use undiluted ARDEX P 51 only with ARDEX-FLEX 7001. 

Use ARDEX P82 or ARDEX P 51 with ARDEX S16/ARDEX E90. 

External Floors 

CEMENT/SAND RENDER AND SCREED 

Wood float finish and prevent rapid drying out. Allow to air dry for at least 2 

weeks (renders) or at least 3 weeks (screeds) prior to tiling.* 

CONCRETE 

Allow at least 6 weeks drying time prior to fixing tiles onto new concrete. 

Ensure all formwork release agents are removed. 


Ensure existing tiling is well adhered and can support the new tile bed. 

Thorough cleaning and rinsing off essential. 

BRICKWORK 

Allow new walls to dry for at least 6 weeks prior to direct fixing or rendering. 

Floor Tiling - Background/Substrate Preparation 

2 

Background/Substrate Preparation 

All backgrounds must be rigid, clean, stable and free from any barriers to 

adhesion such as dust, plaster droppings, grease, polish and any water 

softenable or loosely adhered materials. Good adhesion to a stable background 

is very important to guarantee the successful application of tiling. 

Surfaces to be tiled must be flat and when checked with a 2m straight edge, 

any gap under the straight edge between points of contact with the surface 

should not exceed 3mm (Surface Regularity 1). Any small scale irregularities 

should be pre-smoothed before tiling. 

* With an unbonded ARDEX A 35 cement/sand screed tiles can be fixed after 

only 24 hours, with a bonded ARDEX EB 2 cement/sand screed tiles can be 

fixed after only 3 hours. 

If thinner layers need to be made up, consideration should be given to the use 

of the appropriate ARDEX smoothing compound.

Internal Walls 

Wall Tiling - Background/Substrate Preparation 

CONCRETE 

Allow at least 6 weeks drying time prior to fixing new tiles onto new 

concrete. Ensure mould oil and curing agents are removed. 

CEMENT/SAND RENDER 

Wood float finish and prevent rapid drying of the surface for 1 to 2 days. 

Allow to air dry for at least two weeks prior to tiling.* 

GYPSUM PLASTER 1 3 

Do not use in wet or damp conditions, must be dry and at least 4 weeks 

old. Brush down surface prior to tiling. Where required use ARDEX P 51 

primer. 

PLASTERBOARD 2 3 

Ensure boards are rigidly braced and adequately supported; fix directly to 

the paper facing. Do not skim with plaster. 

AERATED CONCRETE 3 

Allow at least 6 weeks drying time for new walls before tiling or rendering. 

Render should not exceed 13mm in thickness. 

EXISTING CERAMIC TILING 3 


Thorough cleaning and rinsing off essential. In dry locations where 

required use ARDEX P 82 primer. 

WOOD-BASED BOARDS 3 

Avoid if possible, refer to BS 5385:Part 1. If installed, the boards must be 

dry and conditioned to the correct moisture content and their backs and 

edges suitably sealed prior to being rigidly fixed. Where required use 

ARDEX P 82 primer.

Background/Substrate Preparation 

All backgrounds must be rigid, clean, stable and free from any barriers to 

adhesion such as dust, plaster droppings, grease, polish and any water 

softenable or loosely adhered materials. Good adhesion to a stable background 

is very important to guarantee the successful application of tiling. 

Surfaces to be tiled must be flat and when checked with a 2m straight edge, 

any gap under the straight edge between points of contact with the surface 

should not exceed 3mm (Surface Regularity 1). Any small scale irregularities 

should be pre-smoothed before tiling. 

* With ARDEX AM 100 Rapid Hardening One Coat Tiling Render tiles can be 

fixed only 2 hours after application. 

For tiling in dry locations the adhesive coverage should be at least 50%. For 

tiling in wet locations solid bed fixing is required (No voids behind tiles). 

Primers 

ARDEX P 51 - For use on plaster before fixing with ARDEX 

or ARDEX-FLEX cement-based adhesives. 

ARDEX P 82 - Non-flammable, water dispersed epoxy 

primer for bonding to wood-based surfaces and existing

SITUATION 

* If the tiles/slabs to be grouted are prone to moisture absorption and have been fixed with either ARDEX S 16/S 16 W or ARDEX S 20/S 20 W rapid drying adhesives, 

we advise grouting is also carried out using ARDEX MG Rapid Drying Marble and Natural Stone Grout to minimise the risk of moisture staining to the tile edges. 

COVERAGE 

This will depend upon tile size, joint width, depth and the 

Grout Coverage Figure (G.C.F.). Use the following to estimate 

the approximate grout requirements for square or rectangular 

tiles (all dimensions in mm): 

Stage 1. ADD length and breadth of tile together. 

2. MULTIPLY result by joint width. 

3. MULTIPLY result by joint depth. 

4. MULTIPLY result by the Grout Coverage Figure (G.C.F). 

5. DIVIDE result by length of tile. 

6. DIVIDE result by breadth of tile. 

The result is the material requirement in kg per sq metre. 

Quick and easy grout coverage can be calculated using the 

cement and epoxy based grout calculator at ARDEX online: 

www.ardex.co.uk/calculator.asp
