All substrates to be dry to 16% WME (Wood Moisture Equivalent) on Protimeter ‘Surveymaster’ equipment

All loose flaking paint and dust to be removed

Friable surfaces to be removed or made sound using proprietary surface treatment as advised by Impact

All surfaces to be free from grease. Ceramic tiles must be securely bonded to the substrate, thoroughly cleaned and degreased using a suitable degreasing agent and scouring pad, fully rinsed with clean water and allowed to dry. Abrade the surface with a diamond abrasive disc to scratch through the tile glaze and remove all dust. Tiles should be rinsed for a second time and allowed to dry. Use a grinder or sanding equipment fitted with a captive dust bag or vacuum.

Loose tiles to be removed and the area made good using Ardurapide 45 rapid repair mortar, sand and cement with Unibond mix (if drying time permits), Hardwall gypsum render coat or a comparable thickness plywood infill.

Depressions in the substrate should be filled with Ardurapide 45 rapid repair mortar, sand and cement with Unibond mix, or Hardwall gypsum render coat if drying time permits.

All electrical switches, power points etc should be in a first fix state where possible.
All electrical equipment should only be moved or altered by a qualified electrician.

If possible, plumbing and pipework should be removed to be at first fix state and “tails” left protruding from the substrate. Sheets can then be drilled and slid over the pipe “tails”. All holes should be drilled 3mm oversize to allow for expansion. Plumbing should always be carried out by a qualified plumber

Hot pipes and steam pipes should be insulated and a 3-5mm expansion gap should be created when installing sheets around these pipes

All pipes, screw fixings, bolts etc: fixed through the sheet should have minimum 3mm expansion gaps and be sealed using sanitary sealant
