Please Note:

Backer rod diameter should not vary from specified dimensions. If larger sizes are used, increased saw depth is needed.

Sealant bead thickness can increase by up to 25% of design value but may extend curing time.

Never install Roadsaver Silicone to a depth greater than the joint width (1:1 ratio).

Please contact Crafco for additional joint size design recommendations.

You may download or email a copy of your calculations at the bottom of the form.

IMPORTANT!

Deviating from the specified joint configuration may result in extended curing time, premature wear, or sealant overextension and breakage. We strongly recommend consulting your Crafco representative before making any changes to the joint design.
