| 1. PREPARATION: 1-1 Remove any existing skirting, architrave and other
surface timbers.
1-2 Plaster is removed back to the masonry to a height of 1 metre above the external
ground level or last sign of dampness / salt contamination. ( A moisture meter should be
used to detect the affected areas ).
1-3 Rake out all mortar joints to depth of 12mm.
1-4 Remove any timber fixing grounds that are present in the masonry. All fixings should
be applied using Kiltox Aqua-Stik or waterproof adhesive.
1-5 Stainless steel EML should be applied to form a key to ceilings or wall surfaces where
adhesion is poor.
1-6 Tanking pockets should be incorporated into the system to prevent any breach by
fixings.
2. REPLASTERING:
2-1 Gauging water - Must be clean, free from oil, dirt or other injurious chemicals ( use
water suitable for drinking if available ).
2-2 Mix the entire contents of Kiltox Tanking Render No 134 with not more than 4 litres
(water) per 25kg bag of dry mix.
2-3 First Coat Application - compact mix into joints and render to give an overall
thickness of 10mm. When the cement obtains its first set, scratch to form a key.
2-4 Second Coat - the mix is as the first coat and is applied as a further 10mm thick
render, giving an overall thickness of approximately 20mm. To obtain a satisfactory
adhesion between coats, the second coat should be applied to the first before it has set.
Scratch the surface to form a key for the third coat or finish coat as required.
2-5 Finish Coat ( If Required ) - this should be a 3mm thick skim of thistle multi-finish
or similar finish provided it is porous. Do not over trowel.
3. SAFETY:
3-1 (Caution for anyone handling wet mortar) To avoid harm to sensitive skins, minimise
contact with wet cement and mortar (e.g. wear suitable protective clothing). Where contact
occurs (whether directly or through saturated clothing) wash thoroughly.
4. NOTES:
4-1 Where masonry is unstable, it must be made good prior to the application of the
renderings. Where a good bond with the wall is unobtainable, expanded metal lath first
fixed to the wall surface should be used.
4-2 Decoration.
