A wooden deck, typically installed in a home's back yard, is constructed of floor boards, or platform that provides a sturdy, outdoor walking surface. Installation of a deck often leaves gaps between the boards where dirt and other residue can easily penetrate and become trapped. A simple and convenient solution to sealing these spaces is to caulk them. Silicone caulk is a subtle sealant that provides airtight and water-resistant protection.

Things you need
- Cleaning detergent
- Silicone caulk
- Caulking gun
Vacuum the deck surface thoroughly, with extra attention on the boards that require treatment. Soak a mop in a mild cleaning detergent and clean any visible trace of dirt or grime. Allow the deck to air dry.
Cut off the plastic tip on a tube of silicone caulk with a pair of scissors, creating an opening to dispense a bead of caulk roughly 1/4-inch wide or less.
Insert a stiff wire into the opening of the tip to puncture the foil seal inside. Load the entire cartridge into a caulking gun, with the tip pointing away from the trigger.
Align the tip of the gun with a seam between the deck boards. Hold the gun at a 45-degree angle. Insert the tip into the targeted space and steadily squeeze the trigger to disperse the sealant.
Draw the gun along the seam to fill it completely. Quickly wipe up excess caulk with a damp rag before it hardens Repeat the same procedure on other cracks in the deck. Allow the silicone to cure for 24 hours.
