Good surface and joint preparation is the most important pre-requisite for a professional and long-lasting caulking job. It’s what will show others you really know how to caulk. Remove old caulk. Use a putty knife, painter’s 5-in-1 tool or other similar tool to remove all of the old caulk in the joint. A heat gun can be used to soften old caulk and loosen paint to make removal easier. Caulk remover can also help remove all types of old caulk.

Air leaking through holes and cracks accounts for up to 20 percent of heating and cooling costs (or up to 10 percent of total energy costs) in a typical home. Many air leaks are easy to find because they are easy to feel and are located in common areas of the house—especially around windows and doors.

I am thinking what slick and mouse are, that it didn't dry long enough before you painted it. You really don't need to prime the caulk itself but if you have any suspect areas that you are applying it to like bare wood then I would prime those first. Caulk will always stick to primer better than it will bare wood.

DAP caulking question. Does DAP need to be primed before painted? I used alot of it during my last project on the baseboards(white baseboards, white DAP). Now that everything is settling I'm starting to see alot of paint cracking in the mitre joints and other spots that were caulked. I didn't prime these spots.

Concrete, masonry, and stone: Use a wire brush to remove the old caulk, dirt, dust, and loose particles. All contaminants and impurities must be cleaned off, such as concrete form release agents, water repellents, and other surface treatments and protective coatings.

For good measure, start your first caulk line in an inconspicuous area (in case your practice wasn’t enough). Hold the nozzle opening parallel to the joint and apply a 2-3 foot bead. Don’t do more than this because you’ll need time to smooth it before it starts to dry and skin over.

Freshly applied silicone caulk has to seal before you use the shower, and moisture in the air speeds the curing time. Even if the silicone no longer feels tacky, it may not be fully cured. If the air is dry, it may take as long three days before the caulk is cured, according to remodeling expert Tim Carter. For successful application of silicone caulk, surfaces must be clean, mold-free and dry. Damp surfaces or moisture seepage can prevent the caulk from adhering.

Caulk releases an odor during its cure cycle. Most of this process occurs during the first 24 hours after the product is applied. GE Silicone II* caulk is a neutral cure caulk and does not have the vinegar-type odor that is associated with acetoxy cure caulks like GE Silicone I* caulk and most other silicone caulks.
