What is paint?
Vietnam's climate is hot and humid, and it rains a lot, so many homeowners are often advised to paint before painting. Paint or putty paint is the process of applying paint roller with putty putty, which is applied to paint on the surface of the wall to achieve a high smoothness and gloss. This job requires a house painter to have high skills, how to do it carefully and meticulously every detail to achieve the best effect.
Many people believe that due to the hot and humid climate, painting the walls will make the walls more susceptible to mold and peeling. However, that is completely wrong because for spaces with high humidity environments such as bedrooms, kitchens or bathrooms, the use of paint is essential to increase the waterproofing ability of the wall. For inner walls, indoor wall putty is the most suitable to increase the aesthetics and quality of the work, after being painted, the paint on the wall will look much smoother and more polished than painting. directly onto the cement wall.
Why is it necessary to put putty on the walls before painting?
Increase the waterproofing of the wall
Vietnam's climate is a hot and humid tropical climate with a lot of rain, not to mention the rainy days, it is very normal for the walls of the house to be moldy. Paint helps increase moisture resistance, anti-moss mold for walls, especially walls in moisture-prone locations such as bathrooms or kitchens. The most afraid of house paint is moisture from the inside, it is the cause of all paint damage, even if you paint directly, the wall can still be damaged. Therefore, it is extremely important to paint the walls to prevent moisture and waterproof the walls.
Save money and time
Using paint will save the most on paint color costs for homeowners when painting the house. Because, if you directly apply primer to dry walls that still have plaster, the paint will be sucked into the small holes in the wall, to get the desired color, you need to paint over and over again, so it will take time. Time and larger amount of paint means higher costs.
Therefore, in essence, paint is to fill the small holes on the plastered wall to increase the smoothness and limit the situation of paint being sucked in. Moreover, the cost of painting the wall compared to primer and especially color paint is much cheaper, so you will save and spend more time for the homeowner.
Enhance the aesthetics of the wall
Using paint to create a gloss, smooth, and highly aesthetic for the surface of the walls, instead of a rough surface showing traces of cement. Besides, we also have to admit that the use of primer increases the adhesion ability much better for color paints in the following steps. That is the key to creating smooth, beautiful painted walls.
In addition, if you paint the house directly without painting it, it will take a lot of time and effort to thoroughly clean the wall surface before painting. Paint putty is the process of rolling putty on the wall and then using tools such as parchment paper to flatten it until the wall is smooth, putty fills the small holes on the plastered wall so that the primer and paint job later can be applied quickly. and more technically correct.
Indoor painting process
The house painting process is not too complicated as many people think, mainly consisting of 3 steps below:
Step 1: Clean the surface of the wall
Wall cleaning is an important step in the construction process of house painting, which greatly affects the quality of the paint layer. The more durable and beautiful you want the paint layer to be, the better and more thorough the treatment of the wall surface should be.
First, you need to scrape off the old paint on the wall, thoroughly clean the patches of fungus, mold, and stains (if any) then brush the wall surface thoroughly with sandpaper or grinding stone to make the surface smooth and free from scratches. rough. Next, you proceed to handle the openings or cracks, if there are, you need to use cement to patch up immediately. If not, you can switch to putting putty and rolling primer for the walls.
Note: Always wear a mask during cleaning the wall surface to prevent dust.
Step 2: Put putty and primer
What is the use of putty and primer? Matit putty is used to smooth the paint surface, increase abrasion and impact resistance, have high adhesion, form a solid, non-absorbent surface layer to help prevent moisture for the wall, thereby making the surface surface. Paint surface is durable, not moldy. The primer layer will act as a cover for the putty layer and as a transition layer with the topcoat, creating a "primer layer" for the wall, it is resistant to mold and alkali in the best painting way. . At the same time, according to the experience of many house painters, the anti-alkali primer also increases the adhesion and color fastness to the finished paint. Therefore, if you want to have a beautiful paint layer, you should not skip these steps.
Step 3: Roll the paint
When the wall is perfectly prepared, ready for painting, you can use a roller or brush to roll the paint, if you paint high places, you can create more rollers for the roller. For straight walls, push the roller gently from low to high, in turn many times to overlap each other and avoid paint drops on the wall. You should roll carefully, evenly, avoiding thick and thin places that affect aesthetics.
Note: The interval between paints is usually from 30 minutes to 2 - 3 hours, depending on the weather or temperature during the painting process.
Note when using house paint
In general, painting the walls with water-based paint is not too difficult, you can completely do it yourself, but you still need to pay attention to the following issues:
If the wall has been soaked in water, you must waterproof it before putting on putty and painting. After waterproofing, it is recommended to let it dry for 3-4 days, then apply matit and cover with water-based paint to avoid reverse seepage.
The wall surface must be dry from 21-25 days in normal temperature conditions, with the naked eye having the dryness and white color of the plaster, the use of Matit or primer will give much better quality.
After finishing the matt flat, wipe it with a damp cloth or clean the matt powder dust and then roll the primer and water-based paint (especially for glossy paint), doing so, the paint will adhere more tightly and have higher durability.
If using glossy paint, you must use Matit and primer to ensure a smooth surface and good adhesion. Do not use glossy paint for the basement, because there is a lot of steam, the paint film is easily blistered. In this area, you can use semi-gloss or smooth paint because steam can escape, avoiding blistering.
Blistered wall surfaces have been repaired many times, even using a backpressure paint but still not effective, it is imperative to remove the cement mortar and re-plaster before using water paint.
Mix paint with water in the correct ratio, absolutely do not add water in excess of the specified level because this will not ensure the quality of the paint film.
Do not paint when the weather is wet or too sunny, the surface of the construction material has high temperature, so the paint film is easy to blister.
It is recommended to paint two or more layers to make the water color clearer and more durable.
Paint cans must be placed in a safe location, covered when not in use, and out of the reach of children.
Construction in a well-ventilated environment, limit inhalation of paint dust, must wear a mask, appropriate eye protection when sanding and painting.
Treat waste and excess paint in accordance with environmental standards, do not pour excess paint indiscriminately into ponds, lakes, rivers and streams, causing pollution.
