FAQ

What is the maximum thickness per coat?

Typically 15-20mm per coat. For thicker applications, apply in multiple coats with each coat allowed to set before the next. Total thickness varies by product.

Can pre-mixed plaster be used on exterior walls?

Yes, but ensure the product is rated for exterior use. Exterior renders typically contain additives for weather resistance and may require a waterproof topcoat.
