The application of paint on interior plaster surfaces has become increasingly difficult

Inferior plaster work and the tendency to rush painting on damp walls.

Uneven suction effects on poor walls may be generally counteracted by the use of varnish type priming coats – at the risk of cracking and peeling of later paint coats. A better looking job is often temporarily secured on non-uniform plaster, through the use of varnish base primers, but the prospect of future failures is always great.

A study of paint application problems under these changed

Circumstances brought out the importance of the Priming Coat. Prior to the discovery of Vitolized Oil, little or no attention was given to the part which the priming coat played in achieving satisfactory results.

The general practice had been to attempt to overcome the difficulties involved in exterior painting by providing a first coater that would penetrate deeply into the wood, the theory being that such extreme penetration would seal and satisfy the absorption.
