This 750ml tin of undercoat in dark grey is designed for preparation work on exterior masonry and walls. It is intended for use before applying a topcoat, creating a foundation that supports a smooth and uniform decorative finish.
On site, this undercoat is commonly used as a base layer on outdoor surfaces, helping tradespeople achieve consistent colour coverage, especially when covering previous coatings or making repairs. Its dark grey shade can also help with topcoat depth on large or patchy areas.
