Drywall is a very popular option for building partitions, leveling walls and arranging a ceiling. This material can be pasted over with wallpaper, tiled. But Our site of tips decided to tell you how to paint drywall correctly, because this is a very common type of finishing.
First, let’s decide on the choice of paint. Immediately, we note that due to the chemical composition of oil-based paints, it is not recommended to use on drywall! They can just ruin the surface.
Therefore, choose one of the following options:
- Water dispersive.
- Water based paints.
The most popular are precisely water-based paints, although their consumption is slightly higher than that of enamel ones. They perfectly hide small flaws, small irregularities, do not have a smell, unlike enamel ones, which contain a solvent. Water-based paint is very easy to rinse off and wash off, so cleaning after painting will be easy.
Important! For the bathroom and kitchen, choose a moisture-resistant water-based paint.
Paint consumption can be calculated using online calculators. On average, 3.2 kilograms of water-based paint is spent on painting in two layers of an area of 10 square meters. Take it with a margin! Especially if you plan to add color. It will be incredibly difficult to recreate the same shade, even if you paint it first..
Important! There are acrylic, silicate, silicone and mineral water-based paints. All of them are suitable for painting drywall.
Of course, before painting, the wall or plasterboard ceiling will need to be prepared. The portal has already told you how to putty a plasterboard surface using the example of a ceiling. Work on the wall is carried out in a similar way, it will be even easier here. Then you need a primer. Don’t skimp on this process! The paint will lie better, and its consumption will be noticeably less.
To apply paint to a prepared wall or drywall ceiling, you can use:
- Spray gun. Ideal for large workloads.
- Roller. For enamel paint with pile no more than 4 millimeters, for water-based paint – up to 8 millimeters. Use the same roller attachment in the same room. If you want to get texture, choose a nozzle with a pile higher than 8 millimeters..
Important! We do not recommend choosing a foam roller for painting drywall!
- Brushes. Needed anyway. With a narrow brush, you can paint places where the roller fails, including in the corners, on foam or polyurethane skirting boards.
In addition to these basic tools, you will need a roller tray. Yes, you can cut the plastic bottle horizontally, but in a special tray it will be easier to remove excess paint by rolling a roller over the corrugated surface. In addition, if you need to protect adjacent areas or the shade of paint will be different, you will need masking tape..
To work on the ceiling, you can use a roller with a telescopic long handle, but a stepladder or building trestles are still needed to work with a brush in the corners and baseboards.
We recommend starting from the corners where you will have to work with a brush. Circle the entire perimeter of the area to be painted. Now we take a roller, dip it in paint and roll it over the surface of the bath three or four times in order to evenly distribute it and get rid of excess. We paint the walls, of course, from top to bottom.
Roll the roller over the surface in one direction three to four times. Then, before the paint has had time to dry, we advise you to walk again with an almost dry roller in order to accurately get rid of drips and evenly distribute the finish..
Important! Drywall is always painted in at least two layers, when the first is completely dry! Under one layer of paint, the putty will definitely remain visible. According to experts, it is better if there are three layers, but this is at your discretion, depending on the result obtained after the second paint application. By the way, the second layer of paint takes much less.
We advise you to check the quality of the painting with a bright lamp, a lantern, which should be directed at the wall or ceiling at an angle. So you will definitely notice problem areas that have to be repainted..
As you can see, there is nothing difficult in painting the prepared drywall, even a beginner can handle it. Putty usually takes longer.
