CeramicTilePro GRB-CTP-4 Grout Bond Re-grouting Additive

Decided to re-grout my entire master shower. While doing research on line, I ran across this product I have never heard of before, Grout Bond. I watched the video and decided to give it a try. While ordering through Amazon.com, I was advised by Amazon that delivery could take up to two weeks. I agreed and placed my order. That very same day, I received an e-mail from Jason at Ceramictilepro that he was up grading my delivery date and that I would receive my order in the next few days. I was delighted as I could start my project much earlier than previously planned. After using Grout Bond to complete my project, I was totally satisfied with the product. It worked exactly as advertised and turned out beautifully. In fact it turned out so good, my wife now wants me to do the other bathroom. I'm sold on this product and highly recommend it to anyone planning on doing any tile tile/grout work.

I didn't fix the very minor subfloor movement that makes my kitchen tiles' grout crack, and you don't find out until after you bought this that you do have to create the perfect environment for your tile floor or this product will fail. It claims to be more flexible and to make the grout less likely to recrack, but it didn't. It's nothing more than an additive that you can put into mortar and grout that you can buy at the local big box home improvement center, not something specific to grout. I recognized it as soon as I opened the tiny bottle and saw its whiteness and smelled it.

I bought this to help bond new grout to existing grout where it had started to crack. Hoped it would make it steonger/more flexible than the original grout. It's cracking again after a couple months. May help with to keep grout from staining bit that is not what I was looking for in this product.

To early to tell if it really works.

Excellent product. Had some ceramic tile grout that continued to crumble. Adding new grout on top the old never lasted. I mixed up a batch of grout with this product and the grout is now like new with no crumbling. Highly recommend.

was not what I expected, a repair to me doesn't mean take all the grout and then re do the grout as if the tiles just were placed.

Within 3 weeks, the grout loosened again. Grout Bond did not work for me. Money and time for NOTHING! Disappointing.

Used it to bond new grout to the remaining old grout in a tub surround. Did a nice job.
