Spectracryl paints are based on a 100% acrylic resin of exceptional performance, intensity and strength. The pigments are selected for their excellent lightfastness. Colours used in this range are non-fugitive and will not yellow. When dry, these colours will not crack under normal circumstances. Colours are formulated to brush out easily yet retain their structure. The paint dries to a low sheen with sufficient opacity to give good covering when over-painting. Due to their excellent adhesive properties, Spectracryl colours may be applied to most grounds.
