Question On Caulk??? Best Kind

J-Peffer

I just watched the pro caulk video

Winchester

I used some Sikabond a couple of weeks ago instead of PL-whatever. Not nearly as good as PL

I use nothing but GE silicone ll indoors & out, although it is not paintable as it is 100% silicone rubber. You can buy it in almond color which will go with most colored siding. I have changed out windows that I installed a couple years earlier a few times & I had to use a utility knife on every bit of the silicone. Even a little bit not "slit" can hold & it is very hard to peel. This tells me how good it is.................

You can also buy almond for interior...

Up here in Canada we use a product called MULCO supra expert (made by Sico). This stuff does not tool very well (so you have to know how to run a nice bead without touching it!), comes in every color known to man & turns into an elastic-type material that is paintable when dry. This is the standard in window installs where you have swings in temp of from -35 degrees to +30 degrees in a typical year (from -31F to +86F).

I installed windows for a few years for a large window company here in Alberta, I also took an Installation Masters program that exceeds minimum codes in Canada by a long shot (actually follows the strictest building codes in the US!). I wouldn't ever use anything else, especially out here in Canada. The swings in temp. will cause 99% of silicones/caulkings to fail, most can't stretch/compress enough to keeps the bead from breaking.

Tremco is another company makes a similar product but the standard is still MULCO.
Anything that is called a thermoplastic rubber-based sealant would probably do the job, just don't use it indoors (contains xylene which has, put nicely, vomit-inducing toxicity)

The best interior caulk by FAR is Benjamin Moore brand paintable, they have job specific paintable caulk available. An example is "Crown and Trim" but they have others. Lifetime warranty against cracking, shinking, or yellowing and it's elastomeric. It's the only paintable I'll use after years of fighting Phenoseals' shrinking and cracking.

Latex and Ureatheanse... Fail when exposed to UV Rays. So Quad, SOlar Seal, NP1, NP2, Vulkem 116. U will get 2-10 years of life depending on the exposure level.

The silicones listed in the previous posts are ACETOXY cure silicones and are ment to be used in your bathroom and not on the exterior of a building. if you are going to be caulking to any thing that is porous or out side you need to use a NUTRUAL cure silicone. Try using higher end products like Dow Corning 790, 795, 756, CWS ,GE SCS 2000 or Pecora 890, 864. There is a reason these are the products speced on the towers being build around the nation, and its not cause there cheaper, a tube of the above sells for $4-8 dollars a pop but they will actually do what it says on the spec data sheet.

The toughest, most adhesive and most durable caulk on the world market that I have ever come across is Tec-7. I have used this in some of the most agressive environments possible, and have yet to have a failure. This is a standard caulk, yet we use it on floor joints that are subject to constant heavy traffic from machines weighing 12 ton and over. Used in a domestic setting, I cannot recommend it more highly.

I have seen that stuff in the UK and heard that it's very good for bathroom installs. Never tried it my self though. Can you even get it in the US?

Tec-7 meets and exceeds elastomeric spec- it is super flexible and super adhesive, if you can get it, try it, its the bomb.
