– Sealing of expansion joints in the floor area and wall area

3. Advantages and disadvantages of acrylic and silicone
An important advantage is that you can paint over acrylic, has low/no odour.

Disadvantage is that it can not be used in damp places, otherwise you might get mold. Acrylic also draws dust and dirt as it is coarser in structure than silicone. Acrylic has a volume shrinkage during curing  since.

With  silicone  disadvantage is the silicone is not paintable, low cost GP grade has volume shrinkage, strong odour. Advantage, however, is that silicone is permanently elastic silicone as a sealant. 

4. Application of acrylic and silicone
Acrylic and silicone are both dispensed with a caulking gun, battery operated gun or pneumatic gun. They are available in cartridges or sausages.
