In this section you will certainly find the needed details on the application of different sorts of paints on different interior wall surface, ceiling as well as floor products.


New completely dry plaster in good condition, which is to be finished with a paint besides water paint, need to be given a coat of primer-sealer and permitted to completely dry completely prior to being inspected for uniformity of look. Variations in gloss and also tint differences in the case of tinted guides indicate whether or not the entire surface has actually been completely sealed. Otherwise, a 2nd layer of primer-sealer must be used. So a few “suction spots” are apparent, a 2nd layer over these areas may suffice.

A flat, semi-gloss, or high-gloss surface might be related to the primed surface area. For a flat surface, 2 layers of flat wall paint must comply with the priming coat. For a semi-gloss coating, one coat of level wall surface paint as well as one layer of semi-gloss paint need to be applied to the primed surface. For a high-gloss coating, one layer of semi-gloss paint as well as one layer of high-gloss enamel must be made use of over the priming coat.

Before applying water paints of the calcimine type to new plastered walls they ought to be sized, using either a glue-water size or, if the plaster is dry, a slim varnish or primer-sealer.

Cold water paints of the casein kind might be applied either directly to a plastered surface area, or the surface might be first offered a layer of primer-sealer to adjust unequal suction impacts. The very same is true of resin-emulsion paints, with the recommendations of the supplier of the product being offered preference in case of uncertainty. Considering that resin-emulsion paints normally consist of some oil in the binder, they must usually be applied just to plaster which has dried extensively.

Appearance wall paints might additionally be made use of on plaster surfaces. The advantages of this sort of paint are that layer financially produces a distinctive design as well as soothes the uniformity of smooth level paint. It likewise covers cracks or patches in the plaster more completely than common wall paint. The negative aspects of structure wall paint are that they Accumulate dirt as well as are hard to restore to a smooth coating. These materials are available as water-or oil-based paints, are thicker than ordinary wall paints, as well as may be applied to wallboard along with plaster to produce textured effects such as arbitrary, Spanish, mission, and also multicolored.

Structure Wallboard

Make-up wallboard generally presents no particular painting problems if the ordinary safety measures are observed, such as ensuring that the surface area is dry and free from oil as well as oil. The paint treatment for wallboard is the same when it comes to plaster; it calls for a priming and sealing layer complied with by whatever finishes coats are preferred, or may be given one-coat level or resin-emulsion kind paint.


Water-thinned paint might be related to wallpaper that is well- bound to the wall surface as well as does not include dyes which may bleed into the paint. One thickness of wallpaper is more suitable for paint application. Paints aside from those of the water-thinned type might likewise be related to wallpaper by adhering to the instructions provided for painting plaster. Nevertheless, wallpaper covered with such a paint is challenging to eliminate without injury to the plaster.

Wood Walls and also Trim

New interior walls and also wood trim need to be smoothed with sand-paper and cleaned prior to paint or varnishing. To preserve the grain of the wood, the surface may be massaged with linseed oil, varnished or shellacked, and waxed. If an nontransparent coating is wanted, semi-gloss paint thinned with 1 pint of turpen-tine per gallon of paint or the primer-sealer previously explained for wall surfaces might be utilized as a priming coat on wood. 1 or 2 coats of semi-gloss paint should then be applied over the extensively dry prime layer, or if a full-gloss finish is wanted, the last layer should be a high-gloss enamel.

Masonry Walls and Ceilings

Inside masonry wall surfaces and ceilings over quality may, in general, be painted in much the same way as plaster surfaces. Right here once again, it is necessary to enable appropriate time for the masonry to completely dry before applying paint and, furthermore, interest needs to be given to the prep work of the surface area. When enhancing a wall consisting of Portland cement (concrete, for example), it is important to take precautions against the strike of alkali. For this purpose, alkali-resistant guides such as rubber-base paints might be used when oil paints are to adhere to.

Cement-water paints are best fit for application to basement wall surfaces which perspire as a result of leak or condensation. To use these paints, the same treatment must be adhered to as is defined right here for painting exterior stonework walls.

Concrete Floorings

Two basic types of paints for concrete floors are varnish as well as rubber-base paint. Each has its restrictions and also the finish can not be covered without the patched area showing via. Floor as well as deck enamel of the varnish kind gives good service on concrete floors over grade where there is no moisture existing.

Rubber-base paints, which dry to a hard semi-gloss surface, might be used on concrete floors below grade, supplying the floor is not constantly damp from infiltration and also condensation.

Paint needs to not be applied to a concrete cellar floor until the concrete has aged for a minimum of a year. The floor must be dry when painted, the most effective time for application being during the wintertime or very early springtime ( thinking there is some home heating device in the basement), when the humidity in the cellar is low. As a whole, 3 layers of paint are called for on an unpainted floor, as well as the initial layer must be thin to safeguard great infiltration. After the paint is dry, it must be safeguarded with a coat of floor wax.

In repainting concrete floors, where the existing paint has been waxed and is in good condition besides some put on locations, the surface must be rubbed with towels saturated with turpentine or oil spirits and also scrubed with steel wool while wet, to eliminate all wax before painting. If this is refrained from doing, the paint will certainly not stick and dry sufficiently, if the old paint is terribly worn, it needs to be removed by treating with a solution of 2 lbs. of caustic soda ( house lye) to 1 gallon of hot water. This might be wiped on the surface and enabled to remain for half an hour after which the flooring can be washed with warm water as well as scratched with a broad steel scraper. One more method of application is to spread a thin layer of sawdust, which has been taken in caustic solution over the flooring and also permit it to stand overnight. The adhering to early morning, the floor can be washed with hot water as well as the paint scraped off. The surface area should then be washed completely with clean water.
