Favorite interior caulk for windows/doors - Contractor Talk - Professional Construction and Remodeling Forum

davinci · 03-22-2009, 05:09 PM

anyone have a specific brand or compound(silicone ect..) that they prefer?

advanced_energy · 03-22-2009, 05:26 PM

The newest hybrids defy classification

Modified-silicone polymers.
Modified-silicone polymers like DAP’s Side Winder and OSI’s Advantage represent the newest type of sealant available. They are difficult to classify because they combine the chemistry and benefits of water-base, silicone, and polyurethane products into one sealant. They are expensive but worth the money for sealing important outdoor areas like windows, doors, and vents.
thesecan be used indoors and work extremely well. also,DAP Alex plus 35 yr is good for the money.

we rarely caulk inside, if we do its just painters caulk

advanced_energy · 03-22-2009, 10:26 PM

painter caulk for interior is almost a most;however,it must be of a high quality and contain some silicone or else it cracks.

a very good indoor sealant is Dap's Dynaflex. this is sold at home depot and is highly recommended by my installer for interior use. can be used out door as well but we stick to Quad.

What Patrick said. I find the only time you need to cauld inside is because you

up the trim.

advanced_energy · 03-25-2009, 05:39 PM

thats simply not true. there are instances where caulk is warranted and not because we ruined trim.

grob62 · 03-25-2009, 10:17 PM

Sure sometimes you have to caulk when the opening is so out of square that the stops don't cover because you have it maxed out to opposite corners. Or when some shmuck of a install manager can't measure worth a poo. Or sometimes the HO just friggin wants it caulked.

Now for a question. I know quad is used on exterior, but is there any reason it can't be used on the interior. It is paintable and stainable, so what is the downside to using it inside?

The risk of getting calls all night from the HO about the smell

I guess I shouldn't judge other peoples work, we do thousands of windows every year and I'm sure we can count on one hand the number of windows that we might have to caulk on the inside. If its an old house, with out of square openings, sometimes we might have to shim out the back of the extension jams, out on to the window or even change the jams and in some cases just add on to them. Even on old windows that have alot of paint on the jams, we re-cut the side jams with the headed so that all the trim sets flat on to the window.

yea for us its the one or two times a year when you replace those aluminum track double hungs that are only 3" or 3-1/8 thick and you cant put the stops tight to the window without exposing the old Jamb where the casing is.

More common, is the need for one bead where the stool meets the window.

technically Quad can be used interior but the company highly recommends not doing that. why? the odor is powerful and can linger for days causing homeowners to get adverse reactions. in short, DO NOT use QUAD for interior use. as another poster mentioned, Dynaflex 230 is a ubiquitous product that seems to hold very well over time for interior use.

poisgo · 05-09-2009, 12:03 AM

i caulk the inside of every window. why not?

DAP Alex plus 35 year.

olyteddy · 05-09-2009, 04:35 PM

I use Dap Alex Plus and the other Dap Latex caulks for most of my inside work. I like how it dries quick, paints easy and doesn't stink. Okay, it does smell a bit like Bananas...

I use the Alex as well, but not latex-only. I've found that the paintable latex/silicone mix (in any brand) spreads much more nicely than latex-only.

And it leaves my hands silky-smooth.

And it tastes so yummy!
