About this product
A silicone for rubber membranes with the shortest skin time of the Soudal sealants here, about 5 minutes.
Using this specific product
Soudal Silirub EPDM is listed here as the Silicone for EPDM membranes (UK) version for EPDM and rubber membranes. For sealing a joint, the useful question is not simply whether the surface looks finished—it is whether the exact next-action milestone shown above has been reached.
Before you start
- Confirm the package says Silicone for EPDM membranes (UK); related versions can use different timing.
- For EPDM and rubber membranes, pay particular attention to joint depth, tooling, ventilation and exposure to water.
- At 23°C (73°F) and 50% relative humidity.
How to check readiness
Probe an inconspicuous edge for a continuous skin and follow the stated water-exposure milestone. Touch only a hidden edge first; a dry surface can conceal a soft layer underneath.
Avoid this mistake
Surface skin is not the same as through-cure, especially in a deep joint.
