Parex Monoblanco
A one-coat, breathable, weather resistant and breathable decorating render for masonry and concrete walls. Available in 48 standard colours (special colours to order), the render provides an excellent finish and good surface hardening.
Monoblanco / Monorex GF is suitable for machine spraying or hand application and can be finished in a range of styles from smooth sponged or float fine down finish, fine scraped, light tyrolean to heavy roughcast textured finishes.
Monoblanco / Monroe GF is suitable for rendering onto a range of masonry substrates;
Ultra-lightweight, lightweight & dense aggregate concrete blocks. The NHBC 2017 Chapter 6.11 Render, advise the following concrete block categorisation.
Please note: Blocks with a close texture, generally classed as paint grade blocks, should not be rendered without an application of the substrate porosity regulator Micro Gobetis 3000.
Substrates
Suitable for
Masonry and walls conforming to BS 5628-3 and constructed from the following:
n Ultra-lightweight, lightweight & dense
aggregate concrete blocks(1). n Bricks.
n Clay blocks e.g. Porotherm(1)
n Standard low and normal density lightweight
aircrete concrete blocks.
n Breeze blocks (clinker).
n Stone/rubble stone.
n Shuttered concrete(1).
n Expanded clay insulation blocks(1).
n Clean, sound, well adhered existing render. n Base coats conforming to BS EN 13914-1 n PAREX grey weather resistant base coats,
e.g. Monogris E, Parmurex or Tradirex.
n Dry-stacked inter-locking modular wall units
e.g. Durisol recycled timber blocks.
Consult manufacturer’s data sheets.
Durisol with Monorex GM is NHBC approved for single skin external wall construction.
n For below dpc applications and old substrates in accordance with BS8000 – 4 Code of Practice for Waterproofing, consult Parex.
(1) These substrates will require a suction control coat of Micro Gobetis 3000.
Unsuitable for
n Weak mortar or plaster (Gypsum) coated constructions.
n 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.
n Painted substrates – Unless treated with PARINTER. Contact Parex.
Finishes
n Fine Scraped
n Sponge or Float Smoothed*
n Trowel Smoothed*
n Spray Textured – from tyrolean style to
heavy roughcast effect.
For additional information refer to the data sheet on Textured Mineral Finishes.
