weber.set Porcelain Fix 24 is suitable for use on surfaces like :
• Cement-based plaster
• Cement screeds
• Concrete surfaces
• Primed fibre cement surfaces

The following minimum curing periods should be observed before tiling commences: 

• New concrete floors : 28 days 
• New screeds : 28 days 
• New brick walls : 28 days 
• New plastered walls : 28 days 

The walls or floors to be tiled must be wood-floated and not steel-trowelled or power-floated. 

Ensure that all surfaces are clean, dry, sound and free from dust, grease or any contamination that could impair bonding. 

Make good any unsound areas and remove flaky or peeling layers before tiling. Organic growth must be removed and the spores killed using household bleach. 

PVA paint and gypsum plaster must be chipped to expose 80% of the substrate. Enamel paint and bitumen should be scraped and chipped to expose 80% of the substrate. Do not use a solvent or heat to remove bitumen from the surface. 

Existing ceramic tiles must be thoroughly cleaned using undiluted weber.klin Tile Cleaner. Rinse well with cold water. 

Smooth-, off-form-, shutter- or power floated cement surfaces should be acid washed to remove laitance. Rinse well with cold water. 

Once the surface preparation has been completed on the above problem surfaces, the area must be primed using a mix of 2 volumes of weber.prim Plaskey and 1 volume of weber.ad Key-it WB117. Apply to a thickness of approximately 2mm using a block-brush. Leave to dry for 24 hours.

• Tiles should be installed providing for adequate movement joints. Movement and expansion joints to be provided for at approximately 3 metre centres externally or at 4 metre centre internally, in both directions or as per the engineer's specifications.
• All  expansion and movement joints in the substrate must extend through the adhensive bed and tiles.
• Tiles must have full contact with the adhesive-leave no voids.
• Use only dry tiles - do not soak tiles.

• Combine a 20kg bag of weber.set Porcelain Fix 24 with 5.5 litres of clean water and mix to a creamy paste. 
• In wet or permanently wet conditions, replace the water in the mix with weber.ad Bond-it WB183. 
• Allow the mixture to mature for 5 to 10 minutes and re-mix thoroughly. Do not add more water. 

Do not add too much water or attempt to extend the working time by adding more water as this will cause the adhesive to be weak with a tendency to crumble. 

Do not mix more adhesive than can be applied within 1 hour.

Spread adhesive using a notched trowel to a minimum bedded thickness of 3mm on walls and 6mm on floors.

Heavily lugged, grooved or dove-tailed tiles must be buttered to fill any voids with adhesive before placing into wet adhesive.

Press tiles firmly into wet adhesive with a twisting action. Use a rubber mallet to bed large or heavy tiles.

Occasionally lift a tile to check that full contact is being made between the tile and the adhesive.

Do not butt joint tiles.

Clean excess adhesive off the surface once tiles are firmly set using a damp sponge.

Once the adhesive has hardened, only mechanical removal is possible. Minimum grouting joints for walls is 2mm and 3mm for floors.

 Adhesive must be allowed to dry for 24 hours before grouting commences.

Ensure that the joints are free from tile adhesive and any other foreign matter. Allow 24 hours before grouting with weber.grout Tile Grout WB33. Allow 48 hours for sealed or non-porous surfaces. 

In wet or permanently wet conditions, replace the water in the mix with weber.ad Bond-it WB183.

When stored, unopened in a dry place at temperatures above 5^oC, shelf life is 6 to 9 months from date of manufacture.

Contains cement, which is alkaline when wet and can cause skin irritation. Use eye protection and gloves and avoid prolonged skin contact. Avoid inhalation of dust. Wash skin contamination away with warm soapy water. Remove splashes to the eyes by prolonged irrigation and consult a doctor. Do not ingest.
