BOLIX KA is a classic acrylic render with a “lambswool” texture, designed for decorative and protective thin-layer render coats. In practice, it is a proven façade material for thermal insulation systems based on EPS boards and for standard mineral substrates.

The product is ready to use, which simplifies on-site logistics and eliminates errors related to water dosing.

Key properties:

enhanced resistance to weather conditions,
protection against algae and fungal growth,
low water absorption,
flexibility and colour stability,
wide colour range: BOLIX KOLOR SPEKTRUM 300+.

Application:

ETICS systems based on EPS boards,
façades of new and existing buildings,
mineral substrates: concrete, cement and cement-lime plasters,
external applications.

Application method:

prime the substrate with BOLIX OP primer, in a colour similar to the render,
apply with a stainless steel trowel to the thickness of the grain,
texture with a plastic float to obtain the “lambswool” structure,
carry out the work without interruptions – one surface in one working cycle.

Technical parameters:

grain size: approx. 2.0 mm
density: approx. 1.92 g/cm³
thermal conductivity coefficient λ: approx. 0.67 W/(m·K)
diffusion resistance coefficient μ: ≤ 200
water vapour permeability: category V2
water absorption: category W3
drying time: min. 24 h
application temperature: from +5°C to +25°C

Consumption:

approx. 2.8–3.4 kg/m²
depending on substrate evenness and application technique

Practical application notes:

it is essential to work continuously to avoid visible joints and differences,
do not apply on façades exposed to direct sunlight, due to the risk of surface burning,
always use a primer tinted to match the render colour to reduce show-through,
on large surfaces, divide the façade into working sections.

This is a typical, proven acrylic render for ETICS – easy to apply, predictable and durable in use. A good choice for standard façade projects.
