Factors affecting the cost of weather coating

You might pay more for high-quality coatings that are:

  • Anti-algae

These weather coat paints are a sound investment if you live in a coastal, rainy, humid or extreme weather location.

Larger surfaces like roofs and exterior walls will need more paint.

4. Number of coats

Your home may need multiple coats of weather-coating paint for long-lasting results.

This is usually the case for areas with extreme weather, like the north of Scotland.

  • UV protection for anti-fading
