In general, it is necessary to look at the paint color pattern and the wood material in order to make an accurate decision about the painting process.
The experienced guy will decide to minimize paint costs (including labor costs, material costs and time costs), but still ensure quality.
Step 1: Clean
After satisfactory sanding (if not properly sanding, later on, it will take a lot of effort and cost to repair and sometimes fail) depending on whether the required paint color sample is to leave the wood grain or varnish, which determines whether to be powder coated or not.
However, for the most part, for the wood floor sealing coating system, people use a surface gloss paint model, because the paint process is still quite difficult.
Wood-grain coating samples are mainly performed with the NC coating, because the coating of this is thin.
When applying powder coating, it should also be noted that the pattern of wood grain is required on the paint.
If so, the putty must be a pigment (usually black powder, sometimes brown powder). It is necessary to perform this casting step in order to fill the hearts of the wood as well as small surface defects.
Failure to perform this step will take a lot of effort and material to seal these gaps when painting.
Step 2: Stainning
Since a wooden foundation differs from metal, concrete is its color is not uniform at all points.
Therefore, it is necessary to have the color correction step of the wood background, so that the color is relatively homogeneous, so that the finished product in the future will have a uniform color.
How I mix this color I cannot represent because it depends on the color sample as well as the type of wood you intend to use. This requires experienced workers.
With artificial woods they have a fairly uniform color, but in some cases this step is also performed on the entire wood floor to correct the background color to make it easier to do the following steps.
This step is not required for paints with no wooden background. However, with some types of wood with wood floors on different areas (blue or black and white), when painted white.
You should stain to minimize white paint later.
Step 3: Primer 1 time
This is a colorless coating, usually mixed in a 2 : 1 ratio (2 polyurethane with 1 hard powder).
This ratio can be reduced or added with other additives to adjust the evaporation rate of the paint. In hot weather, the rapid evaporation will cause the painted surface to become heart attack or, worse, air bubbles, which will take a lot of repair work.
Most of the hearts are covered in this step. If the workmanship is good with woods, and with a small heartwood and have done well in the past.
You can only need 1 step of priming to reduce the cost of materials, labor and more time – After priming step 1, you must sand and seal defects if any.
Step 4: Paint the first color
As mentioned above, this coloring is determined by experienced painters. To avoid too dark or uneven color, this first paint only paint about 90% of the color sample required.
Step 5: Paint the second color
Complete 100% of the required color sample. This time, the artist will paint darker than the missing color. In this step, it is recommended to arrange a technician more experienced than the first colorist.
Step 6: Primer 2 times
This primer only needs to be thin enough so that the color layer between the color layer does not peel off when sanding, as well as to seal the remaining defects.
Step 7: Urethane topcoat.
Depending on the paint pattern, choose the appropriate gloss. There are several gloss levels of the paint from the matteest level 10, to 20, 30…. and the most glossy 90.
The 10, 20, very glossy matte finish, as well as the very glossy 80, 90 grade are usually more expensive than the middle ones. Usually this phase ratio is also 2: 1 (2 balls with 1 hard).
This rate is reduced or added with other additives depending on the weather conditions.
Note that in addition to the problem of foam as with the primer, if in the evening, early morning, when there is a lot of fog, the varnish will be very susceptible to fading due to saturation of water vapor on the paint surface, so it is necessary to add additives to slow evaporation rate.
This is the finishing coating that determines the quality of the coating a lot, so it is necessary to have a better skilled painter.
Paint room conditions also require more stringent, no dust, especially with high gloss paints.
