Specifications
Typical data values should not be used as specifications. Please contact Simseal for further information. A thin bead of sealant will tolerate more movement than a thick bead. Joint width and depth should be no less than 4 mm. Maximum joint widths should not exceed 25mm. Joint depths should be half the width, with a maximum depth of 10mm. Polyethylene closed-cell foam rod is the recommend backing material to provide the correct depth of joint. If the joint is too shallow, use a polyethylene tape bond breaker. Do not allow the silicone sealant to contact the back of the joint or any staining materials.

Frequently Asked Questions
Can I put new silicone sealant over old?
Do not put new silicone sealant over old sealant because the old sealant will have fallen away or split, causing the leak to continue regardless of how much new sealant you apply. Furthermore, placing a fresh sealer over an old one will be look untidy.
How long should you leave silicone sealant?
In general, most silicone sealants take about 24 hours to completely cure. They can be safely exposed to water, moisture, and other circumstances in normal usage after this point.
Do you have to smooth silicone sealant?
It’s essential to begin smoothing the silicone caulk bead before it dries. It might be nearly impossible to get the desired look once the drying process begins.
How far will a tube of silicone go?
The width and depth of the joint will determine how much caulk is used. At a bead size of 316″, a 1–9 FL. OZ. cartridge covers approximately 56 linear feet.
What will silicone not stick to?
To begin, you should know that silicone will not adhere to anything other than the adhesive system or the PSA (pressure sensitive adhesive). This means silicone doesn’t interact with wood, metal, or any other substance directly; instead, it interacts with the PSA.
How do you remove silicone sealant?
Remove the sealant with a remover.
- Because it’s quick and easy to use,
- Set aside for 3 hours.
- Scrape away the silicone sealant with a gentle scraping motion. Use a sturdy plastic tool
- Using a dry cloth, wipe the area clean.
