The Painting of Interior Walls

Again, as with exterior painting, the preparation of the surface is of prime importance. Far too often this is neglected and results are disappointing.

Before starting to paint, wash or scrape off all calcimine, loose paint, grease and dirt. Fill (jracks with patching plaster and sand to a smooth surface. Touch up patched spots with first coater. Even though no spots or cracks need patching, wash the surface before painting. The work involved will be well worth while.

In attacking the problem from this angle, the fact was lost sight

Of that such a priming coat permitted most of the oil to be drawn into the porous wood, leaving only an oil poor pigment on the surface. This inelastic, oil-drained film became brittle and offered but little resistance to the elements.

The problem, then, was one of obtaining a primer that would not penetrate excessively, thus retaining sufficient elasticity to be durable and resist moisture.

The solution came from the development of Vitolized Oil in the Research Laboratories

The above factors have materially affected painting practices

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
