BASECOATS & ADHESIVES

EWI-065 One Coat Dash Cover (OCDC)

OCDC is a breathable, lightweight and flexible solution to covering over pebbledash. OCDC can be applied up to 20mm thick in one pass, and once dry provides a perfectly flat surface ready to render or paint. This product has a high air content and excellent tensile strength, providing a stable and durable base while allowing trapped moisture within the underlying pebbledash to escape.
Intended Uses
OCDC is intended for masking pebbledash render. The product should be applied as a basecoat, with a Fibreglass Mesh embedded within it. It should then be painted or rendered to achieve a decorative finish.
Application Conditions
OCDC should not be applied in rain or humid conditions, or if wet weather is expected before the adhesive has set.
Product should be applied in temperate weather and should not be used in temperatures above 30°C.
If the materials or the substrate are frozen, or if there is any risk of frost damage within the first 24 hours, work should be postponed.
EWI-065 should be mixed with approximately 5 litres of water per 25kg of dry mix.

EWI-225 Premium Basecoat

As our strongest and most flexible basecoat, the Premium Basecoat can be utilised in two ways. Used in render-only systems, it makes a strong and stable basecoat. In external wall insulation systems, the reinforcing fibres in the adhesive activate to attach either our Mineral Wool or Wood Fibre insulation boards to the wall. Once the basecoat has dried it provides unparalleled strength and flexibility.
Intended Uses
EWI-225 Premium Basecoat is used to fix Mineral Wool insulation boards to substrates in addition to being used within the basecoat layer. The basecoat adhesive is white due to the presence of white portland cement – making it stronger than other adhesives (EWI-220 and EWI-210). Once the product has dried it provides an incredibly strong and flexible basecoat layer. We therefore recommend using the adhesive when applying ‘render only’ systems to substrates for an extra-strong basecoat layer.
Application Conditions
Premium Basecoat should not be applied in rain or humid conditions, or if wet weather is expected before the adhesive has set.
Premium Basecoat should be applied in temperate weather and should not be used in temperatures above 30°C. Likewise, if the materials or the substrate are frozen, or if there is any risk of frost damage within the first 24 hours, work should be postponed.
Setting time is typically between 24-48 hours, depending upon the environment and humidity.
EWI-225 should be mixed with approximately 5.9 litres of water per 25kg of dry mix.

EWI-269 Lightweight Basecoat

The Lightweight Basecoat is a highly breathable, vapour permeable basecoat that compliments both old and new builds. Once dry, the basecoat provides a strong, flexible and waterproof layer. The Lightweight Basecoat is designed for use internally or externally on high performance blockwork, solid brick walls and more. One of the unique characteristics of this lime-based basecoat is that it can be applied at a thickness of up to 20mm in one pass without compromising breathability. It binds gently to substrates due to the presence of lime, offering a level of flexibility that ensures crack resistance on even the softest of substrates. We recommend applying a layer of the Premium Basecoat on top of the Lightweight Basecoat to increase the strength of the system, or insuring your pass is thick enough (8-10mm) in order maintain structural suitability for any finishing coats that require additional application pressure.
Intended Uses
Lightweight Basecoat is a breathable, heritage friendly, limed-based basecoat which is ideal for use on older properties or new builds. The basecoat is suitable for application on high performance zeigel blockwork, autoclaved aerated concrete (AAC), calcium silicate blocks, stonework and solid brick walls.
