What is spray cork? Insulation, protection and style in one finish.

Spray cork is a natural material that combines insulation, protection and style in one seamless finish. It protects your walls against moisture, improves thermal performance and gives your home a refined, natural texture.

Unlike traditional paints or plasters, spray cork breathes with your home. You can even combine spray cork and render on one façade.

  • Bonds to brick, concrete, plaster, wood and metal
  • Elastic — lower risk of cracking
  • Dozens of colours

What is limewash? Lime plaster with a brush.

Limewash is a thin lime plaster applied with a brush. It protects the outside wall, masks small irregularities and gives a natural, handcrafted character.

Limewash suits rural, historic and modern architecture alike. Colour, layer thickness and tool determine the effect — from flat to handcrafted.

  • Vapour-open and moisture-regulating
  • Soft tonal nuances
  • Optional water-repellent treatment
