Yep. Works great. I will lay my bead, spray the caulk and a bit on my finger and tool the joint. No mess and easy to smooth. I just do this with Quad and thick urethane caulk.

I use aerosol foaming window cleaner. We buy it by the case from a local supplier but it is available anywhere.

I use windex on silicones, just like you said. Lay the bead, spray it down, and tool it. Keeps the silicone from smearing all over anything except where the original bead is laid. Learned that from an old countertop installer.

Re: Caulk


I quit using Windex a few years ago because we work with acrylics from time to time and the ammonia can damage them long term. We got used to stocking the foaming kind. But I have done the same thing.

I'll agree they are a pain to work with but the best for exterior applications.

For interiors I used White Lightning for years but they seem to have changed. I'm still searching but I like Loctite and PPG Topgun. I've had Big Stretch fail more than once.

I use denatured alcohol for silicone. Quick mist on the bead and spray my finger before tooling it.

Thanks Andrew. What kind of supplier should I be calling? My normal lumber yard or something different?

We buy our paper towels, glass cleaner, toilet paper for the shop, and other misc items from a local janitorial supply business. If all you want is the glass cleaner try Ace Hardware or the Box stores. Moonshine glass cleaner is a larger name we have used. Just not sure if its sold in your area.

Re: Caulk


I usually use dap for interior, as that's all that's really available here. I always use quad for exterior. I don't usually tool it unless I screw up laying it.

BASF NP-1 for everything exterior and a lot of things inside. It will stick to anything, and with a little 50/50 water and dish soap it tools in real easy with a light touch if you apply a proper bead.

Re: Caulk


I am not impressed with Quad's durability. It gets hard after a couple of years. Superseal had a great thread on here discussing caulks. The Dap Dynaflex 230 I've used lately seems good but who knows in a year or 2. Not a fan of BigStretch. I've used some Dap 3.0 and it seems good.
The polyseamseal/phenoseal is really good, I used it to on a door install in cement foundation 7-8 yrs ago and it is still holding up great even on the threshold.

So far, I've mostly used dap Alex and Alex Fastdry and while they go on good and tool easily, they pull away almost as soon a dry, lol. Cheap crap....

I want to give sikaflex a try, lots of folks swear it is great

Then you're most likely not going to get the life/performance out of it that you should. I've never seen any manufacturer's instructions indicate that tooling is unnecessary.

Though I heartily agree that quad is a PITA to tool.

Typically, but there are definitely caulks out there indicate NOT to tool.

I think Big Stretch is one of those that shouldn't be tooled for it to actually "stretch". I always finger my interior caulk and it's failed. Before it can stretch it has to adhere.

Pretty sure on some caulks it states not to tool.

"Proper bead" is very important. Not saying you don't know what that is but I have seen many people lay a bead down and use their finger and a wet sponge till there is hardly anything left. Really does no good to do it that way.

Wish I could go back and redo all the trim in my house knowing this.

I didn't leave hardly any bead and a lot of it cracked in key areas.

Re: Caulk


I think 3 sided adhesion issues are very often not taken into consideration enough either. (where applicable) I.E. - use backer rod or equivalent when you should. The just fill it with goo approach really restricts the elasticity abilities of the product.

GE 3500 and 5000 were my favorite for general use. The one yard that carried it replaced it with GE max extra about a year ago, and I think the 3500 and 5000 are discontinued. ...At least there's less trips out of my way to pick it up now.

I have a loathing for alex caulks. I feel about as good using it on a project, as I would brushing my teeth with it. It's idiotic that it's the most commonly available, and it's just about the worst thing out there IMO.

I have a lot of faith in sika for critical areas.

The bummer is, unfortunately, at some point you probably will get your wish. To go back and re do it.

....Of course it might piss you off every night as you look at it from the dinner table for 20 years before that happens.

It's already incredibly annoying. It doesn't look awful but I'm ocd.

I'm just not sure it will look right to redo it and brush over the affected areas.
