In this section you will certainly discover the necessary details on the application of different types of paints on numerous interior wall, ceiling and also floor products.
Plaster
New completely dry plaster in good condition, which is to be finished with a paint besides water paint, need to be offered a coat of primer-sealer and also allowed to completely dry thoroughly before being inspected for harmony of appearance. Variants in gloss as well as tint distinctions when it comes to colored primers indicate whether or not the whole surface has been completely sealed. Otherwise, a 2nd coat of primer-sealer must be used. If only a couple of “suction places” are apparent, a 2nd coat over these areas might suffice.
A level, semi-gloss, or high-gloss surface might be applied to the primed surface. For a level finish, 2 coats of level wall surface paint must adhere to the priming coat. For a semi-gloss surface, one layer of level wall surface paint and one coat of semi-gloss paint ought to be applied to the topped surface area. For a high-gloss finish, one coat of semi-gloss paint and one coat of high-gloss enamel should be utilized over the priming coat.
Before using water paints of the calcimine type to brand-new plastered wall surfaces they must be sized, using either a glue-water dimension or, if the plaster is dry, a thin varnish or primer-sealer.
Cold water paints of the casein type might be applied either straight to a plastered surface area, or the surface area might be first provided a layer of primer-sealer to equalize unequal suction effects. The exact same holds true of resin-emulsion paints, with the referrals of the manufacturer of the product being given choice in case of question. Considering that resin-emulsion paints typically consist of some oil in the binder, they need to generally be used only to plaster which has dried out thoroughly.
Appearance wall surface paints might also be used on plaster surfaces. The advantages of this kind of paint are that one coat financially produces a distinctive decor and eliminates the monotony of smooth level paint. It likewise covers cracks or spots in the plaster more completely than average wall paint. The drawbacks of texture wall surface paint are that they Gather dirt as well as are difficult to bring back to a smooth coating. These products are offered as water-or oil-based paints, are thicker than regular wall paints, as well as may be applied to wallboard along with plaster to create distinctive effects such as random, Spanish, goal, and multicolored.
Composition Wallboard
Composition wallboard typically offers no specific painting troubles if the average safety measures are observed, such as ensuring that the surface is completely dry as well as devoid of grease and also oil. The painting treatment for wallboard coincides when it comes to plaster; it calls for a priming and also sealing coat adhered to by whatever finishes coats are preferred, or may be given one-coat level or resin-emulsion type paint.
Wallpaper
Water-thinned paint might be related to wallpaper that is well- adhered to the wall surface and does not contain dyes which may bleed into the paint. One density of wallpaper is preferable for paint application. Paints besides those of the water-thinned type may likewise be put on wallpaper by complying with the directions given for paint plaster. However, wallpaper covered with such a paint is difficult to get rid of without injury to the plaster.
Wood Walls as well as Trim
New indoor walls as well as wood trim must be smoothed with sand-paper as well as dusted prior to painting or varnishing. To protect the grain of the wood, the surface area may be scrubed with linseed oil, varnished or shellacked, and also waxed. If an nontransparent coating is desired, semi-gloss paint thinned with 1 pint of turpen-tine per gallon of paint or the primer-sealer formerly defined for walls might be made use of as a priming coat on wood. 1 or 2 coats of semi-gloss paint ought to then be used over the thoroughly dry prime coat, or if a full-gloss finish is preferred, the last coat ought to be a high-gloss enamel.
Stonework Walls and also Ceilings
Interior stonework walls as well as ceilings above quality may, generally, be repainted in similar fashion as plaster surface areas. Right here again, it is required to enable appropriate time for the masonry to completely dry before applying paint as well as, on top of that, focus ought to be offered to the preparation of the surface. When decorating a wall including Portland cement (concrete, for example), it is necessary to take precautions versus the strike of alkali. For this function, alkali-resistant primers such as rubber-base paints might be made use of when oil paints are to adhere to.
Cement-water paints are best suited for application to cellar walls which perspire as a result of leakage or condensation. To use these paints, the exact same procedure should be adhered to as is described below for painting exterior stonework walls.
Concrete Floorings
2 basic types of paints for concrete floors are varnish and rubber-base paint. Each has its restrictions as well as the surface can not be covered without the patched location showing through. Flooring as well as deck enamel of the varnish kind provides excellent solution on concrete floors over quality where there is no dampness existing.
Rubber-base paints, which completely dry to a tough semi-gloss coating, may be made use of on concrete floors below quality, providing the flooring is not constantly damp from seepage as well as condensation.
Paint should not be applied to a concrete basement floor up until the concrete has actually matured for at the very least a year. The floor ought to be dry when repainted, the very best time for application being during the wintertime or early spring ( presuming there is some home heating device in the basement), when the humidity in the basement is reduced. As a whole, 3 layers of paint are required on an unpainted floor, and also the first layer should be slim to safeguard excellent infiltration. After the paint is dry, it must be protected with a coat of floor wax.
In painting concrete floors, where the existing paint has been waxed and is in good condition with the exception of some worn locations, the surface area should be scrubbed with fabrics saturated with turpentine or petroleum spirits and also massaged with steel woollen while wet, to get rid of all wax prior to painting. If this is not done, the paint will not adhere and also dry adequately, if the old paint is badly put on, it needs to be gotten rid of by treating with a solution of 2 lbs. of caustic soda ( home lye) to 1 gallon of warm water. This may be mopped on the surface and also permitted to stay for 30 minutes after which the flooring can be washed with hot water and scraped with a wide steel scraper. Another method of application is to spread out a thin layer of sawdust, which has been taken in caustic remedy over the floor as well as enable it to stand overnight. The complying with early morning, the floor can be cleaned with hot water and the paint scraped off. The surface area ought to after that be washed completely with tidy water.
