Our home, after many years, has started to show signs of aging. Many people want to refresh it, change the style, or simply choose a different paint color. Repainting the house with new wall colors will make it brighter and feel new again, meeting the desires for change of everyone. Let’s take a look at the steps to repaint the house through this article for a fresh start.

1Steps to repaint the walls properly

Step 1 Clean and prepare the surface

Before starting the process, make sure to remove all moss, dirt, impurities, and any peeling paint or plaster on the old wall surface.

If the surface to be repainted is still new, use a grinding stone or sandpaper to create a good adhesive surface before applying the new paint layer. As for older wall surfaces, after cleaning, wash them with clean water, let them dry, and then proceed with the painting process.

Clean and prepare the surface

Some surface treatment methods:

  • Surface with dirt or powder: Clean with high-pressure water or use a mild cleaner. If the surface has a lot of powder, apply two layers of alkali-resistant primer after cleaning the surface.
  • Surface with old paint/plaster: Old paint layers must be removed by scraping or using appropriate tools. If the surface is not smooth, it should be filled with suitable putty.
  • Surface with moss/mold: Clean with water using high pressure or using tools to remove and treat with specialized anti-moss, anti-mold solutions. Then, rinse again and let it dry.
  • Surface with oil/grease: Use a degreaser and a little solvent (if necessary) to remove the oil stains. Then, rinse thoroughly to remove all traces of oil.

Step 2 Apply waterproof paint to the walls

This step is necessary for surfaces that are not decorated or painted. Applying waterproof paint will protect against the effects of moisture. To achieve the desired effect, choose a good quality cement-based waterproof paint.

Step 3 Apply putty

This is the stage where you can fill in cracks and imperfections to create a smooth surface for interior and exterior walls before applying primer and topcoat. However, depending on the purpose and usage requirements, this step may or may not be necessary.

Step 4 Apply alkali-resistant primer

First, stir the primer thoroughly. Then, use a roller to apply this step. Depending on your needs and conditions, you can apply 1 or 2 coats of alkali-resistant primer. Make sure there is at least 1 hour gap between each coat to ensure the necessary drying time.

In addition, you can add 5 – 10% clean water by volume before application. This will maximize coverage and make it easier to apply.

Step 5 Apply the topcoat

In this step, we will apply 2 coats of topcoat.

Coat 1:

After a minimum of 2 hours to let the alkali-resistant primer dry, we can proceed to paint the first coat.

You can use a paint sprayer, brush, or roller depending on the specific wall surface. Dilute the paint with 5 – 10% clean water by volume before application for maximum coverage and ease of application.

After painting, carefully observe any remaining imperfections from previous steps and fix them before painting the second topcoat.

Coat 2:

Apply the topcoat

Similarly, after a minimum of 2 hours to let the first topcoat dry, proceed to paint the second coat of topcoat.

Using the same painting tools as the first coat, be careful as this is the final finishing coat.

After finishing, use a spotlight to shine on the wall and observe. If the topcoat is even, without any color differences, marks, and the wall surface is evenly bright, then it is considered successful.

2Tips for calculating the appropriate amount of paint to buy

You can use the following method to calculate the amount of paint needed:

Step 1 Calculate the area to paint inside the house
Area to paint inside the house = (Area x Number of floors) x Coefficient for painting inside the house
In which:
The coefficient for painting inside the house ranges from 3 to 4.5.
– If it’s a single-story house without a ceiling – Coefficient: 3
– If it’s a single-story house with few doors – Coefficient: 3.5
– If it’s a multi-story house with moderate door to room ratio – Coefficient: 4
– If it’s a multi-story house with fewer doors and windows – Coefficient: 4.5
Note: The above coefficient is accurate when calculating the overall area of a house, but not for each individual room.

Step 2 Calculate the area to paint outside the house
Area to paint outside the house = Area of the front facade x Coefficient for painting outside the house
Where, the coefficient for painting outside the house ranges from 1.2 to 1.8, depending on the level of decorative details.
Calculate the appropriate amount of paint to buy

Example: Assuming the house has a width (or horizontal measurement) of 5m, length (or depth) of 10m, 3 floors, each floor is 4m high (or there is a balcony), and the house is 1.5m wide, the amount of paint required is calculated as follows:

Calculate the area to paint inside the house
Area to paint inside the house = (5 x 10 x 3) x 4 = 600 m2
Case 1: Rolling the paint directly without primer
Quantity of paint for the house = Area to paint inside the house / Standard of 1 bucket (18 liters) that can cover 4 layers
From the above example, you can calculate as follows:
Quantity of paint for the house = 600 / 5 = 12 buckets of 18 liters.
In which:
– Quantity of primer paint (white paint) accounts for 2/3 = 8 buckets.
– Quantity of colored paint = 4 buckets.

Case 2: Using primer
According to the process of painting the inside of the house with primer, you have to roll 3 layers including 1 layer of primer (white paint) and 2 layers of topcoat (colored paint).
Where:
– 1 bag of putty (40 kg) can cover 40m2 (2 layers).
Quantity of putty for the house = Area to paint inside the house / Standard of 1 bag of putty for the house = 600/40 = 15 bags.
– 1 bucket of interior paint (18 liters) can cover 200m2 for 1 layer, and 70m2 for 3 layers.
Quantity of paint for the house = Area to paint inside the house / Standard of 1 bucket (18 liters) to roll 3 layers = 600/70 = 9 buckets of 18 liters.
In which:
– Quantity of white paint accounts for > 1/2 = 5 buckets of 18 liters
– Quantity of colored paint accounts for < 1/2 = 4 buckets of 18 liters Calculate the area to paint outside the house
Area to paint outside the house = (5 x 4 x 3) x 1.5 = 90m2

Case 1: Rolling paint directly without primer
According to the process of painting outside the house without primer, you have to roll 4 layers including 2 layers of alkali-resistant primer (or white paint) and 2 layers of topcoat (colored paint)
Where:
– 1 bucket of alkali-resistant primer (18 liters) can cover 120m2 for 2 layers
– 1 can of alkali-resistant primer (5 liters) can cover 30m2 for 2 layers
– 1 can of colored paint (5 liters) can cover 30m2 for 2 layers

Quantity of alkali-resistant primer = Area to paint outside the house / Standard of 1 can of alkali-resistant primer to roll 2 layers = 90 / 3 = 3 cans of 5 liters
Quantity of colored paint = Area to paint outside the house / Standard of 1 can of exterior topcoat to roll 2 layers = 90 / 30 = 3 cans of 5 liters

In which:
– Color as the background accounts for 2/3 = 2 cans of 5 liters
– Color as the trim accounts for 1/3 = 1 can of 5 liters

3Some notes when repainting the walls for Tet

Some notes when repainting the walls

  • Handle paint cans carefully and place them in a safe location. In case of spills, clean them up with soil and sand.
  • Wear appropriate masks during the entire painting process.
  • Ensure good ventilation during the painting process. If conditions are not naturally well-ventilated, you need to have supportive devices such as electric fans.
  • Avoid inhaling paint dust.
  • If paint accidentally gets into the eyes, immediately rinse with clean water, then go to the nearest medical facility for treatment.
