Plastic paint for exterior and facade

An exterior paint has to withstand three things that interior paint does not: ultraviolet radiation, wet and dry cycles, and fungi and algae. That is why it contains more resin, light-stable pigments and fungicidal additives. It is the right choice for facades in good condition that only need to renew color and protection.

Paint or coating?
Paint does not cover cracks. If the facade is cracked or uneven, a plastic paint will reproduce the defect and will reopen in one winter. In that case, you need a high-thickness coating or an elastic anti-crack coating. Paint is for sound walls.

What to look at before buying
  • Breathability: the wall must be able to evaporate moisture. Sealing it completely causes blisters.
  • Anti-mold additive: essential in the north, permanent shade, or humid areas.
  • Color stability: intense and saturated tones fade faster than light ones.
  • Indicative coverage: 6–10 m² per liter per coat, considerably less on rough surfaces.
  • Buy everything from the same batch: on a facade, two different batches are noticeable in full light.
How and when to paint
  • 1 → Clean with a pressure washer and treat mold before painting. Painting over it doesn't kill it: it regrows.
  • 2 → Repair cracks and chips and allow to set completely.
  • 3 → Apply primer if the substrate is porous, powdery or very absorbent.
  • 4 → Two coats. Work in complete sections from joint to joint so that overlaps are not visible.
  • 5 → No direct sun, no strong wind, no less than 5 °C, and no rain forecast within 24 hours.
