Directions
 Ensure all surfaces are clean, sound, dry and free from dust. Old silicone should be
removed using a silicone remover.
 Fill any gaps or voids with Alpha Chem Expanding Foam, then trim back to be level
with the edge of the sanitaryware before applying any Pure Anti Mould Silicone.
 When applying to baths, fill half full with water during sealing and while curing.
 Cut thread and then the nozzle to the required size.
 Apply sealant with a sealant gun and tool down with light pressure, within 5 minutes,
using a spatula or wetted gloved finger to ensure bond and preferred finish is
achieved.

removed mechanically.
