Tips For Indoor Paintings

Paint is most effectively applied by painting a number of vertical strokes right next to each other and then spreading them horizontally until you get a plane. Continue to work in areas until the entire area is filled. You consciously choose rollers and brushes that are suitable for the chosen type of paint. The authentic hog bristle brushes, for example, are not really suitable for water-based paint.

The preparation of painting

It seems so easy. A wooden door, a roller or brush, paint, grease, think about the bristles and size, and you’re done. Unfortunately, every successful painting requires good preparation. First of all, you need to make sure the room is ready to paint. Think of covering your floors with plastic, newspaper, or cardboard. Tape off areas not to be painted with masking tape and remove door handles, electrical outlets, door panels, or curtains. If you paint near furniture, make sure that it is also well covered and moved to the side. In addition, think of yourself. Provide adequate ventilation when painting with solvent-based paint and wear a dust mask when sanding. It is best to wear gloves when using corrosive substances.

Substrate preparation

A wooden surface does not necessarily mean a solid wooden surface. There may also be sheet materials such as plywood, plywood, hardboard, or chipboard. These can be painted in the same way as solid wood.

unpainted wood

When painting on unpainted wood, the surface must be smooth, clean, and dry. Make sure you remove grease stains or other pollution with a cleaning agent such as Ruwol Surface cleaner and then rinse well with water. Make sure the wood has dried well before you start painting. Sanding is necessary for optimal adhesion and a smooth end result. For large surfaces, you can use a sander, but it can also be done by hand. The worse the wood is planed, the coarser the grain should be on the sandpaper. Always sand with the grain of the wood and make it dust-free. After this, you can apply a primer for the best result. On untreated wood, you first apply a primer. There are certain types of wood such as Merbau, afzelia, and many dark tropical kinds of wood that contain dyes that are water-soluble. When you paint on it with water-based paint, these dyes will dissolve and cause unsightly stains. Therefore, you should find out carefully which type of wood you use. If the wood contains such dyes, a good insulating primer is recommended. TIP: Use a solvent-based primer as the first coat. Solvent-based primer isolates the dyes in the wood, after which you can continue working with a water-based (primer) paint. Another substrate that can also contain dyes is MDF (Medium Density Fibreboard). It is therefore important to also paint a good solvent-based primer over it.

Painted Wood

The way in which you should process painted wood depends on the condition of the old paint layer. If you are in doubt about the quality of the old layer, there is a simple trick to find out: the adhesion test. In this adhesion test, you make six horizontal and six vertical notches. The result is a small area that resembles squared paper. Make sure there are only a few millimeters between the cuts. Then stick well-adhesive tape over it, press it well and carefully peel it off. If the old paint layer still adheres well, then you will not have a single square on your tape. If he attaches enough, then there are only a few. The paint will not adhere well if you peel off more than half of the squares.

The paint layer is still good

When the test shows that the old paint layer still adheres well, you can start preparing for painting. It is important that pollution such as grease and dust are removed. Dust can be removed with a damp cloth. For grease residues, you can use an alternative cleaning agent, such as Ruwol Surface cleaner. After the surface has been cleaned, it must be sanded. Be careful not to sand through the paint layer. If this does happen, the bare parts must be treated with a primer. After sanding, the surface should be smooth. Then remove the residue with a wet cloth and allow the wood to dry thoroughly before starting the finish. When the old paint layer is still in good condition, you can immediately start applying the final layers.

The paint layer is bad

The adhesion test may also show that the old paint layer no longer adheres well. This is a little more work to prepare, but important nonetheless. An old poorly adhering paint layer has adverse consequences for your paintwork. If peeling paint is present, remove it with coarse sandpaper, paint stripper, or thermal stripping. Afterward, the wood should be sanded as evenly as possible. Then apply a good primer.

woodworm

If you see small holes in your woodwork, it may be that your wood is infected with woodworm. You can see if there are still worms in your wood if small fibers are still visible from the wood. This is called boron flour. Before you start working on this wood, you must exterminate the woodworm. There are various resources for this.
