Common Concerns Answered
What causes the strong odor during application?
The product contains Toluene, a solvent that contributes to its fast-curing properties and strong adhesion but also results in a pronounced odor during application.
How can I remove excess sealant that has cured?
Once cured, excess Sudbury Elastomeric Marine Sealant can be difficult to remove. It is best to meticulously wipe away any excess immediately after application using mineral spirits before it begins to set.
Why is this sealant not recommended for wooden deck seams?
This sealant's properties, while excellent for many applications, are not optimized for the specific movement and exposure of wooden deck seams, which typically require more specialized flexible sealants.
