1 did not remove the wall defects
The walls may have two types of defects that affect the quality of painting: the deviation vertically and not a smooth surface.To measure the deviation, take a 2.5 meter building level and attach it vertically to the wall. If the gap between the instrument and the surface is 5-10 mm, then it can not be aligned, especially if the budget for repair is limited and you make it with your own hands. True, in this case it is impossible to use glossy paint - the distortion will be more noticeable with it.
But if there is roughness, cracks and dents on the wall, they will in any case come across paint and spoil the appearance of the coating, so they need to get rid of them.
How to align the walls
- Plaster. It may be on a plaster or cement basis, eliminate 1-5 cm of the difference and small roughness, small cracks.
- Plasterboard sheets on glue. This is a simple and fast way to get rid of irregularities in 1-5 cm or noticeable dents and cracks on the wall. Sheets can be placed on glue and cover with putty before painting, while the area of the room will not decrease.
- Plasterboard sheets on the frame. This is a way for those whose walls are twisted more than 5 cm. It is worth considering that the frame reduces the area of the room.
- Putty. It will remove the minimum wall defects, therefore usually applied in addition to other materials.
2 did not clean the surface
If you do not spend thorough cleaning of the surface from dust and other contaminants, they are mixed with primer and paint, in the end, even the ideally smooth wall will appear shortcomings and irregularities. Cleaning from dust can be performed with a soft brush, for more serious flaws it is worth using grinding tools or sandpaper.3 Forgot about the primer
Many people think that the primer is needed to align the surface. But it is not. In fact, the composition increases the adhesion of paints with the wall and allows to reduce the flow rate of the finishing material.
Apply the primer is a tassel in two approaches: vertical movements, and then horizontal.
4 did not give materials to dry
If you do not give each layer to dry, cracks may appear and detachment. Drying period for each composition is yours.- Putty. Gypsum - 3-6 hours, cement - 12-24 hours.
- Plaster. Time depends on the thickness of the applied layer, on average the drug dries over 36-72 hours.
- Primer - 6-12 hours.
- Paint. Acrylic compositions and water-based preparations drip 4-8 hours, oil paints - about 24 hours.
5 did not take out
Even if it seems that with the help of the catalog in the store you have chosen a color that is perfect, do not ignore the opportunity to take out. Select 2-3 close tones and apply them with wide strokes (15-20 cm) on the wall next to each other. Spend a couple of days to see how the color behaves with solar and cloudy weather, with natural and artificial lighting.
6 Posted wrong tools
If you incorrectly choose brushes or rollers, the paint can lie uneven and leave the divorces and drips, as well as fly around the room at the time of application.What instruments need
- Wide roller with a long pile for the first layer. He will capture a lot of material and distribute it evenly.
- For the second layer - a roller with a pile length is smaller, about 5-7 mm. It will avoid the flows.
For water-based formulations, take rollers from polyester and brushes with an artificial pile, and for oil paints - with natural.
7 did not measure the amount of Koloranta
Paints can be applied and cravored. In the first case, you buy the finished composition of the desired tone and apply it to the wall. In the second - take the base and add a color paste to it to achieve the desired shade and saturation. It is very important to accurately measure the amount of the kolorant, otherwise repeat the color that you have already applied to the part of the wall, it will not work.
