Can you paint silicone render?
Likewise, can you paint k render?
K Rend touch up paint is also available to carry out small sections of render cover up. Painting over k rend render solves the immediate issue of the unsightly marks found on the render. But painting over k rend just covers over the problem, rather than getting to the root of the problem i.e. the algae growth.
One may also ask, what's the best paint for render? Silicone Paint is a breathable, hydrophobic topcoat finish which is great for applying over the top of an existing render as you would a normal masonry paint.
Keeping this in view, should you seal new render before painting?
We recommend using Dulux 1Step® Acrylic Primer Sealer Undercoat, or Dulux Prepcoat Sealer Binder if your substrate is particularly powdery. Cement render, concrete bricks and mortar must be allowed to cure for a minimum of four weeks, and concrete for a minimum of 8 weeks, before painting with an acrylic paint.
How long should render last?
20 to 40 years
