In fact, I typically purchase the most expensive caulking on the shelf for both interior and exterior painting projects because they flex more, shrink less, and resist cracking better than the others. Just like with paint - probably even more so than paint - there is an enormous difference in quality and life-span of caulkings. I suppose in a perfectly controlled environment where there is no movement or change in temperature and humidity it might hold-up a long time, but in the real world it will often begin to pull away from the sides of the joint pretty quickly. And as long as you don't care if it actually lasts for more than a few months then you're good to go. Luckily painters' caulk is so cheap, right? I mean you can get a tube of basic paintable latex caulking that says '25 Year' right on the side for a little over $1. This is why most painting crews carry at least a couple of cases of the stuff with them all the time.because they use a LOT of it. So the product you will need more of than any other will be caulking - specifically painters' caulk. Regardless of inside or outside, there are more of these areas that will need to be filled than any other kind. On an exterior paint job you could find them where trim meets the siding or body of the house, the butt-joints on longer runs of siding, inside corners, etc. on door/window frames and baseboards), etc. On an interior paint job you could find them where walls meet ceilings, on inside corners of walls, where wood trim meets walls, on inside corners where wood trim meets other wood trim (i.e. There are many places where you may need to fill gaps before you paint.

Follow these tips and you can get a quality finish that can make many professional house painters jealous. In this post we'll discuss those specific products, along with when and where to use them.

In a previous article we discussed Defined Levels of Surface Prep required to achieve various grades of finishes. One of the signs of a great paint job is a seamless finish.

Putty that is painted very quickly, say within a day of application, may take years to harden since the paint (oil only) will further diminish the supply of oxygen.House Painters Pro Tips: Filling Gaps, Cracks, Nail Holes Once the surface hardens slightly, called "skinning," the rate of drying decreases as the source of oxygen is diminished.
The linseed oil reacts with oxygen in the air to harden the putty. Putty's slow drying time is a byproduct of the way it dries, which is oxidation. Predating caulk by decades, window putty was designed to make a seal between dissimilar materials (glass and wood), to remain flexible for a long time, and to be paintable.
They are stickier and thus are difficult to use for window glazing. Other putties, such as painter's putty, are chemically similar but often have a creamier consistency more suited to exterior hole filling. It is mixed at the factory to a consistency that can be worked to a smooth surface without excessive sticking to the tool, or putty knife. Glazing putty is a mix of boiled linseed oil, calcium carbonate and probably other additives that remain the secret of the conspiratorial, world-dominating putty industry.
