Interior painting requires as careful preparation of surfaces as does external painting. The introduction of odorless paints now makes it possible to paint any time of the year. Formerly, most interior painting in the home was done in the tumble or spring, when it was possible to leave the home windows open to ventilate the area. But open windows brought dust particles in to the room to mar the finished painted surface.

A good interior paint job is often 50% planning and 50% painting. Do not rush in preparing the surfaces in your eagerness to get at the brush or roller. If you don't prepare the surfaces properly, you will be back with the paint brush or roller in a couple of months.

In this section you will discover the necessary information on the use of several types of paints on various interior wall, ceiling and floor materials.

Plaster

New dry plaster in good shape, which is to be finished with a paint apart from water paint, should be given a layer of primer-sealer and permitted to dry thoroughly before getting inspected for uniformity of overall look. Variations in gloss and colour differences in the case of tinted primers indicate set up whole surface has been completely sealed. If not, a second coat of primer-sealer should be applied. If only a few "suction spots" are apparent, another coat over these areas could be sufficient.

A flat, semi-gloss, or high-gloss finish may be put on the primed surface. For a flat finish, two coats of toned wall color should follow the priming layer. For a semi-gloss finish off, one coat of flat wall paint and something coat of semi-gloss paint ought to be applied to the primed area. For a high-gloss finish, one coat of semi-gloss paint and one coat of high-gloss enamel ought to be used over the priming coat.

Before applying water paints of the calcimine variety to new plastered walls they should be sized, using either a glue-water measurement or, if the plaster will be dry, a skinny varnish or primer-sealer.

Cool water paints of the casein sort may be applied either directly to a plastered surface, or the surface may be first given a layer of primer-sealer to equalize uneven suction results. The same is true of resin-emulsion paints, with the suggestions of the manufacturer of the product being given preference in the event of doubt. Since resin-emulsion paints typically contain some oil in the binder, they should ordinarily be applied only to plaster which includes dried thoroughly.

Texture wall paints may also be used on plaster surfaces. The advantages of this kind of paint are that one coating economically makes a textured decoration and relieves the monotony of clean flat paint. It also addresses cracks or patches in the plaster extra completely than ordinary wall paint. The disadvantages of texture wall paint are that they Collect dust and are difficult to restore to a smooth end. These materials can be found as water-or oil-based paints, are thicker than ordinary wall paints, and may be applied to wallboard along with plaster to produce textured effects such as random, Spanish, mission, and multicolored.

Composition Wallboard

Composition wallboard usually presents no particular painting problems if the ordinary precautions are observed, such as making certain that the surface is dry and clear of grease and oil. The painting process of wallboard is the same as for plaster; it needs a priming and sealing layer accompanied by whatever finishes coats are wanted, or may be given one-coat flat or resin-emulsion type paint.

Wallpaper

Water-thinned paint may be put on wallpaper that's well- bonded to the wall structure and does not contain dyes which might bleed into the paint. One thickness of wallpaper is usually preferable for color application. Paints apart from those of the water-thinned form can also be applied to wallpaper by following the guidelines given for painting plaster. On the other hand, wallpaper coated with this type of paint is difficult to eliminate without injury to the plaster.

Wood Walls and Trim

New interior walls and wood trim ought to be smoothed with sand-paper and dusted before painting or varnishing. To protect the grain of the solid wood, the surface could be rubbed with linseed oil, varnished or shellacked, and waxed. Franklin Painting If an opaque surface finish is desired, semi-gloss paint thinned with 1 pint of turpen-tine per gallon of color or the primer-sealer earlier described for walls can be utilized as a priming layer on wood. One or two coats of semi-gloss color should then be applied over the thoroughly dry prime coat, or if a full-gloss finish is desired, the last coat should be a high-gloss enamel.

Masonry Walls and Ceilings

Interior masonry walls and ceilings above quality may, in general, be painted in much the same manner as plaster surfaces. Below again, it is necessary to allow adequate moment for the masonry to dry out before applying paint and, furthermore, attention should be directed at the preparation of the top. When decorating a wall structure containing Portland cement (concrete, for example), it is essential to take precautions against the attack of alkali. For this function, alkali-resistant primers such as for example rubber-base paints can be utilized when oil paints are to follow.

Cement-water paints are suitable for application to basement wall space which are damp due to leakage or condensation. To use these paints, the same procedure should be followed as is described right here for painting exterior masonry wall space.
