Limewash on Exterior Walls

Painting with mineral limewash gives a beautiful, matte finish with subtle colour nuances and a natural texture, contributing to an authentic, rustic look.
In addition, limewash is durable, environmentally friendly and easy to maintain. It also protects your exterior wall from weather influences.

The benefits of limewash as a facade paint?

At Paintfactory, we work with mineral lime render for exterior facades. This is a cement-free mortar for interior and exterior use, based on hydraulic lime and mineral fillers.

In addition to the unique structure and personal effect created with Kalei Mineral, this painting technique provides a beautiful, matte finish with subtle colour nuances and a natural texture, contributing to an authentic, rustic look.

Kalei Mineral also protects your exterior wall from weather influences, is durable, environmentally friendly, and easy to maintain. Our system is an open system for both water permeability (W1 class) and water vapour permeability, allowing your walls to breathe optimally.

Mineral Kalei always has a cloudy effect. In rainy weather, this effect is intensified as the lime absorbs moisture and then slowly releases it. If you prefer a uniform look even in rainy weather, you can always finish our mineral kalei with 1 coat of Pearl, a water-repellent, breathable exterior facade paint.

Good preparation is crucial for preventing paint problems and ensuring a durable paint system.
- Ensure that you remove dirt from the surface, including lime, using an appropriate cleaning agent.
- If the substrate is painted with traditional wall paint, you should use Super Paint Stripper Hydro to remove the paint.
Moisten the substrate the evening before you start working with Kalei Minéral.
Apply two coats of Kalei Minéral with a limewash brush. The first coat may show some cracks, which will be corrected in the second coat.
- Allow 24 hours to dry before applying the second coat.
If you want to overpaint Kalei Minéral with Muur Buiten Pearl, you must observe a drying time of 30 days. This paint ensures an even colour and makes the wall easier to maintain.
