General Finishes Extender (118ml)

Regular price £8.95 Sale

Extender is a wetting additive used to extend the open time of any water based stain or topcoat.

I find it extremely useful whenever it's warm and my paint is drying a little bit too quickly.  Also for getting paints flowing easily, in particular when painting large areas with Fusion Metallics. 

  • Easy to incorporate additive designed to slow the dry time and reduce the thickness.
  • Designed for use in all General Finishes stains, sealers, finishes, paints, and glazes
  • Greatly enhances open time, reduces brush marks and over-spray
  • Addition level: up to 20% as needed
  • Does not adversely affect the product, finish or colour. Mixes in easily without generating foam or air.
