Concrete Patch Question

Duct / Duck Tape!!

Not sure anyone can buy concrete in the caulk tube..

Nails rust.

I did. It is made by DAP .... it is concrete. Comes in a tube just like caulk. Got it at Lowe's but read about it on

It isn't really concrete. (concrete starts curing as soon as it is mixed) I can imagine it is some kind of gray aggregate in a polymer or other plasticizer. I would just seal the end up with tape or a cap like you get with a caulk tube and hope. Usually the clock is running as soon as you open them tho.

If I'm going to use the rest of the tube within a few days I'll use a wire nut to seal the spout.

(Actually, even if I'm not going to use it within a few days I'll do the same thing. Then I'll keep it for two years, after which it'll be as hard as a rock and I'll throw it out. I'd save money on wire nuts if I'd just throw the tube out as soon as the project is finished . . .)

I've used painters tape to cover opened tubes...use two strips, crossing over each other. I've kept the tubes and found them in good condition after several months. Nails rust.

I insert a deck screw, then wrap the end with plasic or tape. When I pull the screw out to re-use caulk, the screw threads will sometimes pull out the spout of caulk, leaving the tube usable.

1. It isn't concrete, it is a concrete *patch*. It has calcium carbonate, magnesium carbonate, various chemicals. It dries hard but is not concrete.
2. Use a wire nut on the opened tube.

Hehe-- Yep, it says "Concrete" right on the tube. I've got a can of paint around here someplace that says "Auto" on the label, but darned if I can get any autos out of that can.

Treat it like caulk & you should have similar luck with it. [I'd try to find places to use it up-- more cracks, a mouse hole, a craft project, experiments with a new medium. . . .]

Since Dap doesn't mention trying to save part of a tube, I'd not expect it to have much of an 'after opened' shelf life.

No, you misunderstood! It's Auto-Paint, as in automatic paint. Just open the can, place it on the floor near your car, and go away for an hour. When you come back - your car has a brand new paint job! Really amazing stuff.

D-

Is this the stuff?

If so...its not concrete ....... here is the decription from the DAP tech info

DAP=AE Concrete Patch is a premium-grade, latex sealant specifically formulated to quickly repair small cracks in concrete and masonry. Forms a weather-resistant, watertight seal that helps prevent water and ice damage. Resists cracking and crumbling. Dries to a light color similar to new concrete and blends in with most types of masonry surfaces. Can be painted with most latex based paints. Safe, latex-based, easy water clean-up formula.

or is this it?

but in any case per DAP's tech info....treat it like caulk, re-seal the tip and it will last a while. DAP even makes a little gizmo called a DAP Cap

Thank you.
