Is it essential to completely remove old caulk before using it?

By using this product, you are attempting to seal out water from the underlying tile/shower floor base /tub or sink. It would work best by having the two surfaces prepared cleanly to get the best, tightest seal. Otherwise you might get water trapped under the caulk strip and then mold will grow. So yes, do it right and remove all the old caulk first.

I removed caulk and any dirt as well as rubbing down adhesive area with rubbing alcohol. So far, the product has performed above my expectations.

I removed the old caulk and applied a thin bead of transparent silicon caulk and smoothed it out to be mostly flush. I then applied this strip on top of that and then used the remaining transparent silicon caulk to seal the grout lines along the top. Based on reading the reviews I think sealing the strip after you apply it with transparent silicone caulk is a very necessary step. Just spend some time wiping up the excess and you won't notice the transparent caulk, but you will have piece of mind that the strip will be water tight.

I really don't know but I did remove 99% of the old caulk and the caulk strip went on very nicely and it is still in place with no problems.

No. It is not essential to remove all the old caulk. This stuff don't stick very good anyway.

My shower didn't have much more than the bare minimum to contend with; I did not bother scraping it, though did use product to clean everything thoroughly. So far with much use everything is good shape. If the caulk bead was heavier, than it would be a good idea to remove, since the the new strip would have more solid surface area to bond to.

The instructions call for it but in practice removal of almost all of the old grout is good enough.

I'm not sure if I understand the question, but I believe the answer is no. The directions state that the surface needs to be clean and dry and free of waxing or coatings. I take that to mean that all previous sealents need to be removed. I hope that helps.

It is not seal and enhance. It is charcoal colored caulk. I had to return it.

Not sure about caulking but grout definitely, has a strong smell just in case you have kids or pets.

No.......It's not clear at all. The consistency is thinner and a brownish hue.....And it cures this browish color incredibly strong. If you're planning on using at as a very strong durable caulk that would be fine but know it's not a clear color.

Yes we used a caulking gun, be sure to clean surface REALLY good before using, have patience and a good assistant to help if inside work has to be done. Also we used frog or painters tape to cover any area that needs protecting. It worked great but was messy. Just take your time and it should work well for you.

No. It's great stuff. If I need a clear caulk, typically on glass or plastic, Dap Kwik seal is very good.

Are you applying the Lexel over bad caulking? Then, no, you shouldn't. You should remove all the old caulking and then apply the new caulking material. http://www.amazon.com/Sashco-13013-2-Lexel-5-0-Ounce-Clear/dp/B0012DIUYW/ref=cm_cd_al_qh_dp_t#product-description-iframe

I'd use the primer for it before doing so, but I see no reason it can't be after that, as thats what I did. But you'd also want to "level" the joints in the existing tile before you do, so its not as simple as peel and stick if you want it right.

No the Once N Done is just a cleaner. I would contact the manufacturer to see what they recommend to remove their adhesive. Customer Support

Mine had a lot of small bubbles when i finished. And lines from the squeegee. After a couple of weeks they disappeared. With the exception of 2 very small ones. You can take it off and do it again. I read one of the ratings and the guy said it is not a problem removing, recleaning and does not ruin it at all. So go ahead and redo it.

If you are concerned about leakage I would just caulk around top. I didn't have any problems with mine.

I used Goo Gone but watch how hard you rub. If you have wood veneer finish, it may take it off too.

Yes, use a caulking gun to apply, or put some on the end of something to apply. If you use to repair cooler make sure it is warm and dry to apply let set 24 hours and you should be good to go.

There would be no problem at all. Love the caulk gun. I don't bother using it for small jobs because it is a bit bulky. It has ALWAYS performed like a champ with thick or thin viscosity caulks.

Not if it is in good condition and fully adhered. If it is loose, remove. Clean area first before applying new sealant.

if the caulking is white you're okay. Just spray and walk away. Best stuff ever.
