Application

weberpral M is a weather-resistant exterior render and is ideal for new build or refurbishment projects. Monocouche can be used to produce a range of finishes:


  • Scraped: Applied to a total thickness of 18mm scraped to 15mm.
  • Sprayed roughcast: Applied to a total thickness of 15-25mm.
  • Dry dash: Applied to a total thickness of 15-20mm before applying aggregates.
  • Can be used to create ashlar and quoin features, and is suitable for use on entire elevations, feature panels or smaller areas such as garden walls. 

Description

Through colour monocouche render which can achieve a scraped or roughcast finish – suitable for most types of brick or blockwork.


A single coat render applied in two passes means fast application with shorter programme periods, reduced scaffolding and site costs, as well as earlier completion of ground works.


Features and benefits:

  • Single coat for fast application and shorter programme periods
  • Formulated to be spray applied by render pump for faster application
  • Coloured render for low maintenance with no further decoration required
  • Can be used to create a scraped or roughcast render finish 
  • Weather and algae-resistant 
  • BBA approved certificate no. 17/5464
  • Accepted by the NHBC in relation to NHBC standards

Product Reference

weberpral M

Preparation

weber CL150 Fungicidal Masonry Wash.

Guidance for specification option:

For existing substrates, or where required on new substrates, drench apply CL150 wash and leave for 48 hours, then brush down to remove all moss/ growth.

weberend aid.

Guidance for specification option:

Helps to provide a mechanical key.


Apply with a hawk and trowel in a tight layer 2–3 mm thick to the substrate. Texture the surface using a well loaded roller. Apply no more than 2–3 m² before texturing. It is important that the final texture achieved should be deep, heavy stipple finish with a minimum textured depth of 5–10 mm. Insufficient key will inhibit the render bond; this is particularly relevant on low suction substrates where capillary absorption is minimal. Leave to cure for 48 hours.

Thickness:

-

Manufacturer guidance

  • Mix and apply to specified thickness - this will be 3 mm more than the finished thickness. Rule off with a straight edge to achieve satisfactory in-plane surface. Remove all trowel marks, and after partial take-up, scrape back 2–3 mm to develop the final colour and texture required.
  • The finished thicknesses as appropriate: 15 mm for sheltered areas; 20–25 mm for application in areas subject to severe or very severe weather conditions in accordance with BS EN 13914-1: 2016. Consult manufacturer for further details


Glass fibre reinforcement

weber standard meshcloth.

Guidance for specification option:

To be installed in accordance with manufacturer's recommendations. Balanced, open weave glass fibre meshcloth, coated for alkaline resistance. 1 x 50 m roll.


Weber recommend incorporating weber standard meshcloth into the weberend aid key coat or to the first pass of the weberpral first coat, to areas of typical stress points in the construction.

Surface treatment

Not required.

weberend protect.

Guidance for specification option:

  • weberend protect is a surface treatment for protecting render. Prevents ingress of most types of surface contamination, including water, oil and graffiti whilst maintaining the surface aesthetics and allowing the substrate to breathe.
  • Applied by using low pressure spray, brush or roller.


Accessories/ Other requirements

-

Manufacturer guidance

Render only beads, if required by the system or product, or if specified, shall be of appropriate design, gauge and material - consult manufacturer for details. Structural, temporary or bead fixings shall be of suitable strength and durability. Some available accessories include:



  • Render only base (drip) beads.
  • Stop/ corner beads.


Where window frames incorporating window cills are to be provided by others, then the cill must project sufficiently beyond the outside line of the Saint-Gobain Weber render system to a recommended 40 mm minimum - consult manufacturer for further details.

Coverage

21 kg/m² at 15mm application dependent.

Curing time

Curing with a fine spray of clean water may be necessary during rapid drying conditions, In hot climates curing as above is essential for 3 – 5 days after application.
