Parex SikaWall 508 Monorex GM Ash Grey Render 25kg

Create a defined grey façade with Parex Monorex GM G50 Ash Grey Render. The colour is incorporated throughout the mortar, providing a decorative surface that does not rely on a separate coat of masonry paint. Ash Grey can be used across a complete property or applied to rendered areas within a façade combining brick, cladding or stone. Its grey colouring works particularly well within modern exterior schemes featuring dark roofing, metal details and contemporary window frames.

Monorex GM is a semi-lightweight, one-coat render for vertical masonry and concrete. Its weather-resistant but breathable formulation helps protect the wall from rainwater while allowing water vapour to pass through the finished surface.

Product specification:

Shade: Ash Grey
Colour reference: G50
Texture: Medium grain
Product type: Through-coloured one-coat render
Finish options: Medium scraped, spray textured or smoothed spray texture
Application: Manual or spray machine
Capillary water absorption: W2

Pack size: 25kg

For a medium scraped finish, apply the render to approximately 18mm before removing no more than 3mm during scraping. The completed weatherproofing coat should have a minimum thickness of 15mm.
