Overview
KingSeal SA200 is a one-part Acetoxy Cure Silicone Sealant, which cures rapidly on exposure to moisture vapour to form a resilient elastic silicone rubber. KingSeal SA200 contains a fungicide to help reduce the incidence of mould growth on the sealant when used in bathrooms, kitchens, etc.
Where to use
Recommended for use in sanitary applications, sealing wall joints formed in ceramic tiles in bathrooms and kitchens and perimeter joints formed around UPVC frames.

How to use
Method of use
Joint Preparation
The joint surfaces must be clean, dry and free from all contamination. Primers may be required on some substrates. It is recommended to use masking tape on each side of the joint to maintain clean and uniform joint sides.
Joint Backing
Where applicable, appropriate joint filler e.g. closed cell polyethylene foam, should be used to provide the correct joint depth.
Application
KingSeal SA200 is supplied in cartridges and can be applied into the joint using caulk gun.
Apply KingSeal SA200 into the joint starting from the bottom, ensure that the joint is completely filled. Tool the surface of the sealant within 15 minutes of the application using a spatula or suitable smoothing liquid.
This will provide a smooth finish and will ensure good contact between the sealant and the substrate. Remove the masking tape directly after tooling the sealant.
Limitations and notes
- Not recommended on porous substrates such as concrete, stone and marble.
- Not recommended to be used on bituminous substrates or substrates based on natural rubber and EPDM.
- KingSeal SA200 can corrode mirror, silver, copper, brass and lead.
