Why should you back rolling after spraying?

Many people mistakenly think that just using a paint sprayer is enough. However, the process of paint back rolling after spraying paint helps bring higher efficiency. It is thought to be due to the following factors:

●      Texture

If the spray paint ensures good coverage of the surface, the back rolling creates a uniform but soft texture on the newly sprayed surface. Therefore, the back rolling process helps the paint to be covered more evenly on the surface as well as overcomes all the disadvantages that spray paint does not get.

The process of back rolling the paint after spraying helps the paint surface texture to be smoother and more even.

●      Adhesion

Spray paint will help the paint to be diffused onto the surface of the wall or ceiling. At that time, its adhesion is not completely good. Using the roller to back roll will affect the paint on the surface and optimize the adhesion of the paint to the surface.

In other words, it will help promote maximum adhesion of each paint layer compared to just stopping at the spray step.

●      Obstacles on the surface

Builders recommend that you should roll back after spraying to ensure maximum removal of obstacles on the surface of walls or ceilings. During the back rolling process, you will easily recognize the remaining defects and deal with them.

If you just spray paint without re-rolling, these defects may be temporarily covered but will show up over time.

Frequently Asked Questions

1. Is surface preparation important before painting?

In order for the paint coating to be smooth and adhere well, the preparation of the construction surface should be done carefully.

  • For new construction

With new construction (newly built house), the wall surface needs to be dry enough to be able to carry out the steps of painting the house. The wall humidity should not exceed 15%.

Too much humidity causes the paint layer to degrade quickly, causing peeling, blistering or patchy colors.

In ideal and dry weather conditions, you can wait for about 3 weeks after plastering, the paint can be applied. In fact, depending on weather factors, the waiting time for the wall to dry can be up to 2 or 3 months. This is known as the wall curing period.

Thanks to this time, the contaminated impurities contained in the bricks and mortar will decompose, helping the construction surface to be stable.

After that, you should clean the surface with fine sandpaper to remove the remaining sand particles on the wall and then proceed to clean the dirt. The wall surface meets the standards when there is no sand, dirt, moss or any other factors that reduce the adhesion of the paint.

  • For old construction

With old walls (repainted houses), it is necessary to remove all moss, dirt, impurities and old paint that has peeled off before re-painting. If the wall surface is still new, you can use sandpaper or grinding stone to create a foothold for the new paint layer.

After cleaning, you need to rinse with clean water, wait for it to dry, and then apply a new paint layer.

For both methods, do not forget to back rolling after spraying.

2. Should I use a paintbrush, paint roller or paint sprayer?

The paint application tool can be a paintbrush, roller brush or paint sprayer. Depending on the specific wall surface, you choose the appropriate construction tool.

  • Paintbrush

The paintbrush is the best tool for areas with narrow, rough surfaces, small areas, lots of detail or angles.

  • Paint roller

Although the roller brush has the advantage of helping you complete the job faster, the edge of the roller is very soft, so it does not create a sharp paint line like a brush. Therefore, if you have time, you can extra use a paintbrush to take care of every detail.

Meanwhile, roller brushes are designed for use on large surfaces. Thanks to rollers, the paint is evenly and smoothly covered on the entire surface without leaving marks.

  • Paint sprayer

On the other hand, when using water-based paints, the paint sprayer is the optimal choice because it will save you considerable effort and time during construction.

Therefore, depending on the purpose of use and specific wall surface, you should take advantage of all available tools to create the most perfect paint.
