Primers and undercoats
How to use primers and undercoats
Can I leave primed timber exposed externally for long periods of time?
This is not a good practice as the primer does not provide a surface that is resistant to weathering and the elements. Primed surfaces that have been exposed may need to be prepared and re-primed. Generally the finishing coats need to be applied as soon as possible. Preferably within 7 days.

Why do I need to prime bare timber?
Priming bare timber is essential for the success of the whole paint system. The primer soaks into the timber creating a good bond and quenches the absorbency. This provides a sound base for the next coating.

Acrylic Primer Undercoat can be used on a variety of correctly prepared surfaces such as wood, metal and plaster. It's ideal to have in the van for those unexpected situations and everyday use.
