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.
– Strain and connection joints in interior design
– 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.
How long does it take for the acrylic sealant to harden?
Ambient humidity and temperature are the key factors. Water evaporates from the acrylic so it hardens more quickly in warm and dry conditions. Joint dimensions are also relevant. Hardening occurs from the outside in.
Which substrates can acrylic sealant be used on? Is a primer required?
Paintable Acrylic sealant is primarily used on absorbent, porous substrates. If the substrate is too damp, the acrylic may take longer to harden.
Primer is generally not required for application of acrylic sealant. . This sealant is not suitable for waterproofing.
How should an existing acrylic joint be reinforced or repaired?
Acrylic joints can be repaired using the same material. The adhesion between old and new acrylic is good. Any existing sealant must be clean and securely attached to the substrate
