What to fill the gaps in the wall or ceiling?

Acrylic sealant is a ready-made mass that is designed to seal or even out a given surface. Applying sealant to wall joints is important because it protects against cracks and scratches in the paint coating. In addition, it has an aesthetic function. Most acrylics come in white. These are sealants that can be painted with paints.
Which acrylic to choose?
There are several types of acrylics, depending on the task we have to perform. We can distinguish:
- paintable acrylic - sealing compound for the inside, which is used to connect walls, walls with other elements (including skirting boards, windows, windowsills, doors, shelves, etc.)
- light acrylic putty - acrylic mass, which is used to fill cavities in the walls.
- acrylic for the outside - a sealing compound that is resistant to weather conditions and moisture
- acrylic with grain - acrylic mass, which is designed to imitate the structure of traditional plaster.
Can acrylic be sanded?
Yes. You have to remember to choose light acrylic putty - only it is suitable for sanding. Other acrylics are flexible and cannot be sanded.
Light acrylic filler is a quick sealer that acts as a ready-to-use repair compound for wall defects. After application, wait about 20 minutes and start sanding until a smooth and even surface is obtained.
What about cavities in the outer wall?
For outdoor applications, acrylics that are resistant to weather conditions and moisture should be used. Acrylics are available, which have a smooth surface, and acrylic with grain, special for filling gaps in plasters.
When can I paint after applying acrylic?
Most acrylics cure at a rate of 2-3mm/day into the joint. It is important not to start painting before the acrylic has hardened, because acrylic loses volume during curing. If you apply the paint too quickly, scratches and cracks will appear over time.
However, there are acrylics that have a modernized formula and allow painting immediately after sealing.
These are :
- immediately paintable acrylic - 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 occurrence 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:
- type of sealing that we want to make (joining walls, filling cavities in walls or filling holes in plaster)
- the place where the seal will be
- acrylic hardening time (when we plan to start painting)
All types of seals are guaranteed by the SAXBO acrylic base:.
- immediately paintable acrylic - acrylic with low shrinkage, which can be painted immediately after application.
- internal-external painting acrylic WZ - acrylic with high flexibility and resistance to weather conditions. It is perfect for connecting walls and walls with other elements, such as baseboards or door bands.
- light acrylic putty - a quick putty that fills holes and cavities in the walls. It is ideal for dry construction.
- 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.
