Rh the floor oily, just a sufficient amount to take up the dust. If shellac is to be used over the stain, use turpentine for cleaning. Apply over this stain a thin coat of shellac or good liquid filler. Rub off lightly with fine sandpaper or steel wool and apply a coat of floor finish. This can be left in the gloss, rubbed with pumice stone and oil, or sandpapered to kill the gloss, then waxed in the usual manner.

Should a deeper stain be wanted or the floor be marred or scratched, use a mixture of 1-3 stain and 2-3 floor finish. If the floor has not been protected before the plastering was done, it should be thoroughly cleaned, the mortar scraped off, sandpapered and dressed down smooth and the cracks filled with crack and crevice filler or puttied with good putty; then apply a coat of stain, after which the floor can be finished as noted.

Plastered walls should receive a coat of size before painting. The best size which can be applied to a wall is a thin coat of oil paint. This is hard to apply without showing laps, but these can be easily covered with subsequent coats. When hard dry, apply a coat of warm glue size which will fully stop absorption.

If the walls are to be painted in oil with a full gloss, they should receive the finishing coat of a full oil reduction. If to be half flat, the finishing coat should be mixed to a good consistency with half turpentine and half oil. This will cover the work in a solid manner and make good two coat work.

If a varnish size is used, reduce a fair grade of hard oil finish or varnish to a thin consistency and apply freely with a full brush. When hard dry, apply a first coat mixed with half oil and half turpentine.

If a full gloss is desired, the finishing coat of full oil reduction can be applied over this surface, or, if half fiat
