Ceramic tiles from floors and walls.

Vinyl tiles and sheet from floors and walls.

Timber mosaic and parquet from floors

Papers and vinyl from walls

Laminated plastics from backing

Causes of breakdown include:

Ceramic tiles bedded in cement mortar - sub standard mortar, tile suction (i.e. tiles not soaked before laying), no provision for thermal movement in restrained positions, pre-setting or drying of screed.

Rectification requires relaying to correct procedure, and incorporation of mastic filled control joints as may be necessary.

Moisture in sub-surface. This can cause lifting of adhered ceramics, vinyl and timber mosaics. Testing can establish adequacy of dryness of sub-surface. Laying must be carried out with the recommended bonding agent.

Wall papers and vinyl's lose adhesion because of excessive suction of the subsurface. Porous backgrounds require sealing
