Do you know how to apply caulking sealant？

Caulk is a flexible material used to seal air leaks through cracks, gaps, or joints between stationary building components and materials. For components that move -- doors and operable windows, for example -- caulking sealant is the appropriate material.

Although not a high-tech operation, caulking can be tricky. Read and follow the instructions on the compound cartridge, and remember these tips:

For good adhesion, clean all areas to be caulked. Remove any old caulk and paint, using a putty knife, large screwdriver, stiff brush, or special solvent. Make sure the area is dry so you don't seal in moisture.
Apply caulk to all joints in a window frame and the joint between the frame and the wall.
Hold the gun at a consistent angle. Forty-five degrees is best for getting deep into the crack. You know you've got the right angle when the caulk is immediately forced into the crack as it comes out of the tube.
Caulk in one straight continuous stream, if possible. Avoid stops and starts.
Send caulk to the bottom of an opening to avoid bubbles.
Make sure the caulk sticks to both sides of a crack or seam.
Release the trigger before pulling the gun away to avoid applying too much caulking compound. A caulking gun with an automatic release makes this much easier.
If caulk oozes out of a crack, use a putty knife to push it back in.
Don't skimp. If the caulk shrinks, reapply it to form a smooth bead that will seal the crack completely.
