Technical Specification


Python SA is a premium, highly flexible and high performance silicone sealant for walls and floors. Python SA is a low modulus, neutral cure and non-staining silicone sealant meaning it is suitable for use with sensitive natural stones such as granite and marble*. Python SA contains advanced Anti-Mould technology that will protect against mould growth. The Python SA colour range has been specifically developed to compliment the Python CS colour range and all colours of grout have a matching silicone.

Python SA has two main areas of use:

• For sealing joints between sanitary ware and ceramic, porcelain and natural stone tiles in bathrooms, kitchens, showers and wet rooms in both domestic and commercial environments.

• For sealing movement joints in wall and floor tiling.

Python SA is a low modulus, neutral cure sealant with excellent adhesion properties and it is suitable for use on a large variety of surfaces including ceramic, glass, porcelain, natural stone, PVC and wood. When cured Python SA is highly flexible and will accommodate movement between two surfaces. Python SA is waterproof and it is ideal for use in areas subject to prolonged wet conditions e.g. showers, wet rooms etc. Python SA is very easy to apply, smooth and clean off and it is suitable for interior and exterior use.


Before starting, all surfaces must be clean, dry and free from dust, dirt, oil, grease and other contaminants that may affect adhesion.


For internal use the recommended minimum joint depth is 6mm.

1. Cut off the tip of the Python SA cartridge, ensuring the screw-thread is left intact.

2. Screw on the nozzle and cut the nozzle tip to a 45O angle with the nozzle diameter equal to the joint width.

3. Place the Python SA cartridge in a caulking gun and apply a steady bead of silicone sealant to the required area.

4. Within 10 – 15 minutes of applying the Python SA, smooth the sealant with a wet jointing trowel, a finger dipped in soapy water or a silicone finishing tool.

5. Allow the Python SA to cure. Allow at least 3 days before contact with water.

PLEASE NOTE: When applying Python SA to a bath, it is recommended to fill the bath half full with water whilst sealing. Leave the water in the bath for 24 hours to allow for full cure of the sealant.

NB: Python SA is suitable for use with natural stone tiles, but suitability with very porous natural stone tiles must be tested prior to use. Do not use to seal Aquariums, or areas that are fully submerged in water e.g. swimming pools, or with bitumen / asphalt.

Although Python SA contains anti-mould technology, the joints should be cleaned with appropriate household cleaners and/or disinfectants in sanitary areas to help prevent mould and mildew growth.
