Parmurex is a one-coat weather resistant grey render for internal and external walls. Suitable as a grey coat finishing render or as a base coat for receiving a decorative finish. e.g. MONOREX GM & GF, MONOBLANCO, & REVLANE. Suitable Substrate Masonry and walls conforming to BS 5628-3 and constructed from the following: Dense aggregate concrete blocks. Dense bricks. Breeze blocks (clinker). Stone/rubble stone. Shuttered concrete. Clean, sound, well adhered existing render. Base coats conforming to BS EN 13914-1 Below dpc applications and old substrates in accordance with BS8000 – 4 Code of Practice for Waterproofing – consult Sika for guidance. Unsuitable Substrate High-suction, weak or old substrates, Ultra-lightweight & lightweight aggregate concrete blocks, clay blocks, standard low and normal density lightweight aircrete blocks. Dry stacked inter-locking modular wall units e.g. Durisol, Velox etc . Weak mortar or plaster coated constructions. Exposed vertical substrates with a backward incline above 10 ° – a backward incline may affect water run off and may have a tendency to hold moisture. Substrate Primer Shuttered concrete and other nonabsorbent substrates, first apply a coat of ready-to use MICRO GOBETIS 3000 or a key-coat made up by adding 0.5 L of 751 LANKOLATEX to the mixing water volume for 25 kg of PARMUREX. On wet or wet patchy substrates or where different materials have been used it is advisable to apply a key coat made up by exchanging 0.5 litres of water for 0.5L of 751 LANKOLATEX or FIXOPIERRE for the mixing volume for a 25kg bag of PARMUREX. Allow the key coat to fully dry a minimum of 48 hours before the application of the next coat. This suggestion will assist against the effect of ‘block ghosting’ and shade variation.
