Q How do MS Polymer Sealants compare to other types of sealants?
A MS polymer sealants excel in flexibility, durability, moisture resistance, chemical resistance, and UV resistance compared to other sealants. They are also user-friendly, making them easier to apply and handle.
-
Q Can I paint over Silicone Sealant?
A No, it will peel off. To achieve a paintable sealant joint indoors, it is important to use a good-quality acrylic sealant.
-
Q What mileage can I expect from a 300ml cartridge of Silicone Sealant?
A Use the following formulation: 300 Where: L = Length of sealant in metres obtained per cartridge.
L = 300 / W*D
W = Width of the joint in mm D = Depth of the joint in mm.
A joint of 5mm width and 5mm depth yields approx. 12.0m per 300ml cartridge
A joint of 4mm width and 4mm depth yields approx. 18.8m per 300ml cartridge

Q Why does colored Silicone Sealant fade?
A Colored silicone sealants are tinted with inorganic or organic pigments. Inorganic pigments have limited colors but good weather resistance and are not prone to fading. Organic pigments offer a wide range of colors but have poor weather resistance and fade easily. It is recommended to choose inorganic pigments for tinting to avoid color fading.

Q Where can Silicone Sealants be used?
A Silicone sealants can be used in a wide range of applications, including:
Construction
Plumbing
Automotive
Electrical
Household repairs
-
Q Can I apply new Silicone Sealant over old silicone?
A For the best adhesion, we recommend removing the old silicone. New silicone will bond to old silicone, but the bond is not as strong as it would be on a clean surface.
-
Q What is the difference between Acetic Silicone and Neutral Cure Silicone?
A Acetic silicone sealant releases acetic acid during curing, while neutral silicone sealant does not. Acetic silicone sealant cures faster but may not be suitable for sensitive materials. Neutral silicone sealant is versatile, adhering well to various surfaces, making it ideal for sensitive applications where avoiding acidic byproducts is crucial.

Q How do I use Acrylic Sealant?
A Step 1: Surface preparation
Step 2: Installing the sealant with the gun
Step 3: Sealing: Squeeze the sealant gun to fill the cracks or joints and spread it evenly.
Step 4: Inspection and painting: Clean any excess sealant by gently wiping it with a cloth.

Q Where are Acrylic Sealants suitable?
A Water-based acrylic sealant is one variety of acrylic sealant, which can be widely used in interior decoration, general construction expansion joints, and general engineering joint waterproofing and sealing in non-long-term immersion environments. For example, it is used for sealing the gaps between interior walls, baseboards, door and window frames, and walls. It has good adhesion to porous building materials.
-
Q What is the shelf life of most Caulking products?
A 18 months from the date of manufacture when stored in a cool and dry place.
-
Q How soon after I apply Acrylic Sealant can it be overpainted?
A Water-based paints can be applied 20-30 minutes after the application of the sealant.
-
Q Can I paint over Acrylic Sealant?
A Yes, you can. This is one of the main features of an acrylic sealant. Be aware that if the sealant experiences significant movement, and the paint is less flexible than the sealant, the paint can shrink and crack.
-
Q Why should I use Acrylic Sealant over a silicone sealant?
A If your joint needs to be painted over, then use an acrylic sealant as silicone sealants cannot be painted over. Acrylic sealants are suitable for use in contact with porous building materials whereas acid-curing silicone sealants are not suitable for adhesion to cement, concrete, and other strongly alkaline surfaces.
