Yes, sealant tooling is always recommended in order to coat or wet the substrate surface, which is needed to promote maximum bonding. The common procedure involves properly filling the joint first and then dry tool the sealant by pressing and pulling a round tipped spatula across the sealant surface. This step forces sealant into joint surfaces and helps removes air pockets or voids at the bond line. Some will tool by wearing a rubber glove and tooling the joint with their finger. Others may use tongue depressors or other similar tools.
