For all types of painting work, in addition to the quality of paint, other things that also need to be considered are the wall surfaces and the painting methods. A bad wall painting result often occurs. This is due to the wall conditions and the painter’s skills. So, the right method of wall painting needs to be explained to make a beautiful and efficient wall painting. In this article, we will explain how to paint for new walls and old walls.

Paint A New Concrete Wall
How to paint a new concrete wall, first, make sure that the wall condition is completely dry (at least three days). High humidity levels indicate that the wall is not completely dry. If the wall is still damp, the painting result will have low quality. A moisture meter is a tool to check the wall’s humidity levels. Although determining the wall’s humidity levels can be known using the naked eye. A completely dry-wall has a white (pale) surface and feels dry when touched.
The wall’s alkaline level should be measured using a pH meter pen. Ideally, the wall’s pH should be below 12. If the pH is above 12, then the alkaline should be neutralized with a solution of 3% phosphoric acid and 2% zinc chloride, then rinse it with clean water.
After the wall is completely dry, also make sure that there is no more dirt and dust attached to the wall. For that, you should first clean the surface of the wall with a compressor or wet rag. If necessary, the wall can be cleaned with sandpaper. After the wall is clean, then the first coat of paint can be applying. After the first coat has dried, paint it again for the second coat. If using high-quality paint and the weather is normal, the painting process will take around 3-4 hours.
It should be noted for painting interior walls. Before painting, the wall must be given a filler or putty first. For exterior walls, the painting process can be applied directly.
Paint An Old Concrete Wall
The old wall that had previously been painted, the surfaces need to be cleaned from dust and dirt. The presence of dust and dirt will make the paint not attached perfectly or the painting result is not good. However, before it is decided to do repainting or not, it needs to start with a simple three-step test as follows.
- The first step, it is necessary to observe the wall surface, whether there are bubbles or moss.
- The second step, wipe the wall surface using your hands to test whether efflorescence has occurred or not. If there is fine dust in the hand, it shows that the paint chalking has occurred so that the wall is not good to be painted directly.
- Third step. Throw water on the wall. If the water is absorbed into the wall, then the paint layer will change the color. That indicates that your wall should not be painted directly. Especially, if there are bubbles, it can be ensured that the paint doesn’t adhere to the wall anymore.
If one or three of these steps occur, then two options can be solutions before repainting. First, the entire layer of old paint is peeled off. Or the second option, old paint is washed with a brush and soapy water. If you choose to wash it, then the wall must be completely dry before repainting. While, if the peeling paint is your choice, make sure all the old paint coats are completely clean from old paint. The process of peeling paint can use a putty knife (scraper).
Especially for old walls that have been moldy or mossy, the surface can be brushed first using clean water mixed with detergent. If it hasn’t disappeared, the mildew can be exfoliated with a chisel. Furthermore, give a putty on the wall, then painted. To make the walls free from mildew attacks, you should use anti-mold paint.

Wall Tile Installations and Material Requires
Ceramic tiles are not only applied to the floor but also the walls. Generally, ceramic tiles are installed in damp or wet areas in the house, for example in bathrooms/toilets, kitchens, and other areas. Meanwhile, some people install ceramic tiles for exterior walls of the house.
Wall Preparations for ceramic tiles
Ideally, before installing ceramic tiles, it needs to be planned carefully. Planning is required so that when installing ceramic tiles will be correct and appropriate. To make planning for ceramic tiles installation, several things must be determined, as follows.
- Determine the type of ceramic tile, whether for interior walls or exterior walls. It is better to choose the type of ceramic tile that suits the area conditions.
- Calculate the entire wall surface area and the number of ceramic tiles needed.
- Determine the color, size, and ceramic tiles motif.
- Determine the desired installation method, whether open joint or closed joint installation. An open joint is a ceramic tile installation that uses a wide grout, while the closed joint uses small grout.
- Determine the desired pattern, parallel or diagonal.
When purchasing ceramic tiles, it is recommended to buy additional ceramic tiles about 10% of the required (for parallel installation), or 15-25% for diagonal installation. This is to anticipate when installing ceramic tiles if there is a ceramic tile that needs to be cut. For diagonal installation, you will need more ceramic tiles to be cut. Also, the additional ceramic tiles have a function as ceramic tiles reserves, if in the next years you need to replace your broken ceramic tiles. This is very important because some manufactures in the future no longer produce ceramic tiles with the same type anymore.
To determine the quality of ceramic tiles, then before you buy it, you should take a look at the packaging. This examination needs to carried out immediately before the packaging is damaged. Each package must have the same code in quality, style, color, and type. The quality of ceramic tiles is usually coded grade 1, grade 2, grade 3, or grade 4. Besides quality, it is also important to check out the caliber or tonality. Caliber or tonality is a group of sizes created when ceramic tiles are produced and color variations in ceramic tiles. This must be considered so that the size and ceramic tile color have the same type.
How to install wall tiles
Basically, there are two methods of installing ceramic tiles for walls, small grout installing and wide grout installing. Each of those methods has a different purpose. For that, before deciding the methods, you need to know the advantages of those methods.
Wide grout advantages
- Has bigger wall surface flexibility.
- Has tolerance against ceramic size differentiation.
- Easier grout process and spread evenly
- More efficient flexible joint usage. The flexible joint has a function to neutralizing when ceramic tile expansion occurs. A flexible joint is installed between ceramic tiles.
- Looks better for a garage, carport, or other wet areas to prevent slipperily.
- Infrequent tiles popping up due to sufficient expansion space.
Small grout advantages
- Neater floor surface and giving special looks if using high-grade ceramic tile.
- Faster grout process and efficient.
- Unseen floors join, but popping up ceramic tile will easily occur.
Some cases will occur at home when ceramic tiles are not perfectly installed. For example, tiles popping up. Mostly, the caused why ceramic tiles get popped-up by the following things.
- The change of wall shape. Several factors are the burden to the wall, foundation shifting, earthquakes, and so on.
- The mortar mixing is using low-quality materials.
- Not perfectly mixing mortar although using good quality material.
- The lack of cement or not meet procedure requirements.
- Wall shrinkage
- Ceramic tiles are not soaked in water first when installed.
- Too many gaps under the ceramic tile.
Material needs
For wall tile installation, the material needs are sand and portland cement for mortar and filler grout (tile grout). The material needs for 1 m² wall areas are as follows.
- 1 box of ceramic tile
- 0,03 m³ of sand
- 0, 16 sacks of portland cement
- 03 kg of tile grout
To make a better wall tile installation, instant cement should be used. Instant cement has some advantages, such as
- more sticky and elastic,
- not dry quickly,
- more resistant to shrinkage and expansion,
- high adhesion,
- In sunny weather it can dry about 10-20 minutes.
When using instant cement, the mortar’s thickness is only 3 mm and it will need 5 kg instant cement per meter square. For ceramic tile installation can also be used 5-7 kg portland cement per meter square.
