hi i'm mark osborne i'm the founder of manor works painting matterworks painting is the largest residential only painting company in the metro area we're celebrating our 10th year in business today we're talking about painting an interior of a room we've already finished our sanding which is the second step in the surface preparation process and we're ready to move on to the next step something called caulking caulking is a type of product or a sealant used to seal seams and cracks that exist be where surfaces meet in this case we're going to be using a siliconized latex based caulk in this case the area where the baseboards and the walls meet does not need to be caulked because it was done recently but there are other areas that need to be caulked in this particular case we're going to be re-caulking where the panels of this door meet where some seams and cracks have developed caulking is applied with a caulk gun and the first step is to cut a small opening at the tip of the caulk at a 45 degree angle then simply hold the gun at a 45 degree angle pull the trigger and apply a small bead of caulk along the seam the key is to not apply too much product which would then have to be removed once the caulking has been applied you would like to smooth it out either with a finger or a wet rag for an interior situation a latex siliconized caulk could probably be the best once the caulking has been complete now it's time to move on to the next step in the surface preparation process something called priming to watch the other segments in this video series or for how-to videos on almost any other topic visit monkeysea.com
