Acrylic or silicone

Acrylic and silicone are sealants that are very similar in texture and appearance. Sealing compounds are used in every house or apartment where the task is to fill up joints. But whether you use acrylic or silicone depends on a few factors. Above all, of course, from the areas of application of the two sealants.

1. What exactly is acrylic and what exactly is silicone

Even if silicone and acrylic are similar in texture and both products are rubbery when cured, they can still be distinguished. Acrylic appears matte and silicone is glossy. But experts rather than laypeople recognize this difference. The fact is that silicone and acrylic are two very good sealants.

2. Applications of silicone and acrylic

As a layperson, you would like to know where silicone and acrylic are used. This question is very easy to answer.

silicone Due to its elastic properties, it is used in areas where the ground is mobile or works. Since silicone is water-repellent, it is used very often in the sanitary area. And sanitary silicone makes it very difficult for mold to develop because it is fungicidal, which is very important in a damp bathroom. Silicone is permanently elastic and therefore best suited for joints in the bathroom, kitchen and expansion joints. However, silicone joints can also be beneficial in the kitchen or in your own laundry room. The best way to use silicone is to draw silicone joints to seal the shower or the bathtub.

- Expansion joints and connection joints in the sanitary area
- Sealing of expansion joints in the floor area and wall area

acrylic is a plasto-elastic sealant that also offers some advantages over silicone. Acrylic can be painted over and can therefore be used for cracks in masonry, which is unthinkable with silicone. Acrylic is used wherever there is no or little contact with water. So in no damp room. The acrylic sealant is used to seal joints and connections that do not require great expansion. Small fluctuations are okay and are compensated for by the acrylic sealant. The acrylic sealant adheres really well to plasterboard, masonry, glass, wood and plaster.

- Expansion and connection joints with low loads in interior construction
- Joints and connections to concrete, aerated concrete, plaster, masonry, wood, plasterboard, fiber cement, roller shutter boxes, window sills, etc.


3. Advantages and disadvantages of acrylic and silicone

acrylic has advantages and disadvantages. An important advantage is that you can paint over acrylic. Another disadvantage is that acrylic is permeable to water. This means that it cannot be used in damp places, otherwise you could get mold. And unfortunately there is another disadvantage, acrylic also attracts dust and dirt well because its structure is coarser than silicone. Acrylic also shows a decrease in volume during hardening because it gives off water and has a long hardening time, but has little odor.

Even with that silicone it looks no different with the advantages and disadvantages. A disadvantage is that silicone cannot be painted over. One advantage, however, is that silicone does not shrink in volume. Another advantage would be that silicone is permanently elastic as a sealant. Another advantage is that silicone is water-repellent! On the other hand, silicone can produce a vinegar smell when it hardens, which is usually the case with sanitary silicones, as they release acetate as a decomposition product to the humidity during the hardening process. But there are also low-odor silicones.

4. Processing of acrylic and silicone

Acrylic and silicone are both processed with the hand gun, battery gun or compressed air gun. So they are processed with cartridges or tubular bags. With both materials, you should also peel off the surface with your finger or a spatula. This way, there are no small cracks or holes that would look unattractive or that would make the sealant not really tight. With the acrylic sealant, however, the finger must first be moistened with water. If you want to process silicone, you have to know that a smoothing agent is needed as a release agent in order to create a nice silicone joint. If you do not use this, the grout will either stick to the tool or your finger and you would pull the compound out of the mold, which is not the point.

5. Conclusion on silicone and acrylic

The acrylic sealant and also the silicone have advantages and disadvantages and different areas of application. If you use acrylic or silicone correctly, these two do their job as a sealant very well.
