Window sealant provides protection to various surfaces from dust and insects that may come through that gap. Its main characteristic is that it stays flexible even after you paint it which makes it essential for joint filling in construction, as when it is cured it becomes like rubber in terms of quality and building joints need to have the ability to move at some point.

Acrylic vs silicone sealant

Acrylic or silicone sealants look very similar in texture and appearance. Sealants primary purpose is to fill gaps. Whether we use acrylic or silicone, depends on several factors.
1. What is an acrylic sealant and what is a  silicone sealant

silicone and acrylic are similar in nature and in the cured state are rubbery, so can we distinguish between the two . Acrylic is matte and  silicone glossy.

2. applications of silicone and acrylic

Silicone has good elastic property and preferred in areas with joint movement. Anti fungal silicone  is used in bathroom and kitchen  Silicone is permanently elastic and therefore best suited for joints in the bathroom, kitchen and expansion joints. 
– Expansion joints and connection joints in sanitary areas
– Sealing of expansion joints in the floor area and wall area

Acrylic is a plastoelastic sealant that offers some advantages over the silicone. It is paintable and can be used  for cracks in masonry, which is unheard of with silicone. Acrylic is ideal for applications where no contact or little contact with water.  The acrylic sealant keeps really well on plaster, walls,  wood and plaster.

– Joints and connections to concrete, aerated concrete, plaster, masonry, wood, plasterboard, fiber cement, shutter boxes, window sills, etc.

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.
