The cool, dry autumn weather is the best time for you to take steps to paint your house. The most beautiful is around the end of August, September, October of the solar calendar. Choose this time, because the weather is not humid, the paint will dry faster, it is also easier to perform the steps. You can still paint your house in other seasons of the year, but you should avoid the time of prolonged rains or when the humidity is high because the building will be dry and possibly peeling, absorbing moisture, ...

However, it is not advisable to paint the house when it is too sunny because the solvent evaporates faster when encountering high temperatures, which will reduce the paint adhesion, easily cause peeling, cracking, wrinkling.


Choosing the right home paint colors is a very important step. But do not worry too much in this step because most paint companies on the market have a rich color palette to choose from. You should choose a quality paint company, and a skilled painter to make sure you get it right.

To save money, the calculation of the amount of paint to buy is also one of the important things in the steps of painting a house. You need to know the coverage of each paint to calculate the exact amount of paint to buy. Coverage is the number of m2 that 1 liter or 1 kg of paint can be applied to the surface of an object to be painted such as walls or metal. Coverage also depends on whether the surface to be applied is flat, or curved, or undulating. Accordingly, the amount of paint needed for rough surfaces will be more expensive than for conventional flat surfaces.

To calculate the exact amount of paint to buy, you can refer to the table below:

The steps to paint the house include: Surface cleaning -> Construction of waterproof paint -> Mastic -> Alkali resistant primer
-> Roll the first layer of paint -> Roll the second layer of paint.

The general rule of painting is to paint from outside to inside, from top to bottom. You should paint from difficult areas first to easier areas.

Specifically, the steps to paint the house are:


For the coating to be smooth, to adhere well, the preparation of the paint surface needs to be done carefully.

With new construction, steps to paint the wall can only be done when the wall surface has reached the required dryness. If the humidity of the wall exceeds 15%, it will cause the paint film to degrade quickly, causing peeling, blistering or color mottling. In ideal, dry weather, you can start painting with about 3 weeks after applying. In fact, waiting for the wall to dry on average can take up to 2 or 3 months. This can be considered as the wall maintenance period, so that contaminated impurities in bricks and mortar decompose, helping the construction surface to be always stable, and "healthy". Remove the remaining sand particles on the wall by cleaning the surface with fine sandpaper and then proceed to clean the dirt. The surface of the wall with no dirt, dust, moss or any other factors that reduce the adhesion of the paint is up to the standard.

Clean the wall surface before painting

With old walls (the house is repainted), before painting, we need to remove all dirt, moss, impurities and peeling old paint. If the surface of the wall is new, use sandpaper or abrasive stone to beat the wall to create adhesion to the new coating. After cleaning, you must rinse it with clean water, wait for it to dry, then start painting

When treating wall surfaces, you should keep the following in mind:

  • Wall surface containing sand, powder, dirt: Clean the surface with a high pressure hose. You can also incorporate a mild detergent for even greater results. In case the surface has a lot of powder, apply 2 more alkali-resistant primers after cleaning the surface.
  • Wall surfaces containing plaster, cement mortar, old paint film: Poor wall surfaces should be leveled with measures such as chiselling, rubbing, scraping the paint film, and then re-plastering with a suitable powder.
  • Wall surface contains fungi, mold, moss: Clean the surface under strong tap pressure. You can use additional scraping tools, chisels or fungicides. Then rinse the wall surface with clean water and allow to dry naturally.
  • Oil and grease wall surfaces: Use a mild detergent and a little solvent if needed. Finally, rinse thoroughly with clean water to completely remove the stain.


Waterproofing is an important step in the painting of houses, in order to protect the building from the effects of rain and moisture. This stage must be paid more attention to in a country with a tropical monsoon climate with as much rain as our country.

waterproof construction for the wall

First, you need to check and waterproof the construction surface in contact with water sources such as outdoor walls, or near flower beds, fish tanks to achieve the best results. After that, we can carry out waterproofing from behind the water source or waterproofing areas not in direct contact with water.


Putty (matit) is used in the steps of home painting to create a flat surface for walls, cover cracks and defects before priming and coating. At the same time, it also helps to increase the texture adhesion to the paint in the future. As noted above, flat surface paints are less expensive than undulating surfaces because the amount of primer and topcoat required will be less. Therefore, the use of matis to create a flat surface for the wall not only increases the aesthetics, but also makes painting the wall simpler, faster and more economical. Have 1 to 2 layers of putty or do not use putty, depending on the requirements and the purpose of the use. However, you should note that the plaster thickness should not exceed 3 mm to avoid cracking, deforming the paint film, or peeling off.

bait mastic

Mix the matis bait with water in the ratio of 3: 1, use the stirrer until the mixture reaches a homogeneous consistency. Next, apply 1-2 coats, each time applying 1 layer about 2-4 hours apart. Wait 4-6 hours before sanding. After sanding, wait 1-2 days for the surface to be firm before cleaning and applying the primer.

Note, after mixing matis powder should be used immediately for about 1-2 hours otherwise the powder will be dry, hard can not be used anymore.


In the steps of house painting, primer is responsible for preventing alkali (in cement, lime), preventing moisture, preventing osmosis, and enhancing the waterproofing ability of the wall surface. You can choose to paint 1 or 2 coats of your choice. Skipping the primer step usually does not affect the construction process, however, in the long term, will affect the quality and aesthetics of the paint color, causing the coating to be alkaline, patchy, not All colors. On the other hand, you will spend more topcoat if you do not use primer, as the putty will absorb the topcoat. The primer is much cheaper than the primer, so if you want to save money, don't forget the priming step. Even white coatings have a higher cost than primers, but are not resistant to alkali, prevent moisture, create adhesion, smooth as well as primer.

Paint coating is like a shirt that protects a wall, and makes it more eye-catching. Normally, people will paint 2 coats instead of just 1 coat because 1 coat of paint cannot guarantee aesthetics and quality. The two coats of coating, although it takes more time and costs, will create a more beautiful, smooth, color film, helping the beauty of the wall stay longer.

The first coat will be applied at least 2 hours after the alkali-resistant primer has been applied.

Before application, dilute the paint with 5-10% volume of clean water to increase the coverage, as well as make the application easier. With the wall surface painted directly (without the putty matis), the paint should only be mixed with no more than 5% of clean water.

Roll the first color paint

Application tools can be brush, roller or spray paint depending on the specific wall surface. Paintbrush is the best tool for areas with narrow, small, rough, detailed, angular surfaces. The roller makes painting quick, but the edge of the roller is very soft, so it doesn't create a sharp and tight paint line like a brush. Therefore, you should use a roller to paint large surfaces that will help the paint coat quickly, while ensuring even and smooth over the entire surface, without leaving marks.

After finishing the first coat, it is necessary to check the remaining points of the previous paint steps so that they can be promptly repaired before moving on to the second coat.


Roll the second layer of paint

After about 2 hours of finishing the first coat, you can apply the second coat, which is also the last one. Tools and procedure are the same as for the first time as mentioned above. However, because this is the final finish, it is necessary to be very careful and meticulous when applying. After painting is finished, use a flashlight to illuminate the wall to see if the coating is even, there are paint brush marks on the wall. If there is a problem, you can repaint it to fix it, or find the appropriate measures.
