What to fill in the defects in the wall or ceiling?

In this article you will learn:

- Which acrylic to choose?
- can acrylic be sanded?
- What about the defects in the outer wall?
- When can you paint after applying acrylic?


Acrylic sealant is a ready mass that is designed to seal or even out a given surface. Applying sealant to wall joints is important because it protects the occurrence of cracks and scratches in the paint coating. Additionally, it has an aesthetic function. Most acrylics are white. These are sealants that can be painted over with paints.


Which acrylic to choose?

There are several types of acrylics, depending on the task we have to do. We can distinguish:
- painted acrylic - sealing compound inside, which is used to connect walls, walls with other elements (including skirting boards, window, window sill, doors, shelves, etc.)
- light acrylic putty - acrylic mass that is used to fill in the holes in the walls.
- acrylic for the outside - a sealing compound that is resistant to weather conditions and moisture
- acrylic with grain - acrylic mass which imitates the structure of traditional plaster.

Can acrylic be sanded?

Yes. You have to remember to choose acrylic light putty - only it is suitable for sanding. The remaining acrylics are flexible and cannot be sanded.
Light acrylic putty is a quick sealant that acts as a ready-to-use repair compound for wall defects. After applying, wait about 20 minutes and start sanding until a smooth and even surface is obtained.

What about defects in the outer wall?

For outdoor applications, use acrylics that are resistant to weather conditions and moisture. There are acrylics with a smooth surface and acrylic with grain, especially for filling gaps in plaster.

When can you paint after applying acrylic?

Most of the acrylics cure at a rate of 2-3 mm / day into the joint. It is important not to start painting before the acrylic has cured, as acrylic loses its volume during curing. If we put the paint too quickly, scratches and cracks will appear over time.
However, there are acrylics that have a modernized formula and can be painted immediately after sealing.
These are :
- acrylic immediately paintable - acrylic mass that can be painted immediately after application, using the "wet on wet" method. This quick-drying acrylic has minimal shrinkage, thus minimizing the appearance of scratches and cracks in the walls
- light acrylic putty - in this case, painting is allowed 20 minutes after applying the sealant.

What to look for when choosing an adhesive?

When choosing acrylic, pay attention to:
- the type of sealing we want to make (joining walls, filling holes in walls or filling holes in plaster)
- the place where the seal will be
- acrylic hardening time (when we plan to start painting)
- flexibility

All types of seals are guaranteed by the SAXBO acrylic base :
- acrylic immediately paintable - acrylic with low shrinkage that can be painted immediately after application.
- internal and external painting acrylic WZ - acrylic of high flexibility and resistance to weather conditions. Perfect for joining walls and walls with other elements, such as skirting boards or door bands.
- acrylic light putty - a quick putty that fills holes and cavities in the walls. Ideally suited to the implementation of drywall.
- acrylic with grain - acrylic sealant imitating the structure of plaster. It can be used outdoors thanks to its increased resistance to weather conditions. Perfect for facade paints.
