What does it do in render?
It improves the workability of the mix and reduces water penetration through the finished render, acting as an integral waterproofer.
Do I brush it on or mix it in?
It is integral, so you add it to the gauging water and mix it through, rather than applying it to the surface.
Where can I use it?
Internal and external rendering.
Is it just for waterproofing?
It does both: it plasticises the mix for easier working and waterproofs the set render.
How is it different from a mortar plasticiser?
This is tuned for render with a waterproofing action. For bricklaying and pointing mortars, use Liquid Mortar Plasticiser or Power Mix.
What size is it?
5 L, as a single or a box of 4.
