Bon Tool 21-167 Grout Bag Super-Flex Silicone Tip

I see that this product is no longer available less than a month after purchasing it. That's unfortunate because it is the best mortar bag I've ever used. It is strong (feels like rubberized plastic) yet, it is very thin and flexible. It is easy for someone with smaller hands to keep the mortar twisted down toward the tip. Although it came with a metal tip insert, that was too small an opening for our needs. We even cut about 1/4" off the end to allow more mortar to be piped into gaps. Also, the construction is such that permanent creases run along each side. This allows you to pinch the end to reach into some smaller joints.

I have my own masonry business so I have been through hundreds of grout bags. The $8 Marshalltown bag that Lowe's carries will last me between 5-8 uses before they tip wears out and is to big. The $6 bag menards sells are more comfortable but the side blows out after 4 or 5 uses. This bag is by far the best one yet. Its rubber, light and easy quick clean up. I'm on the 6th use and have not had to cut the tip once. HERE IS A TIP FOR D.I.Y.ers- Grout bags work well with mason mortar mixes like type S and type N (NOT THINSET MORTATS). If your bag is clogging make your mix wetter. Also rinse every couple fill ups.

This bag is GREAT!! It's very lightweight, very flexible and strong enough to handle squeezing pressure (so far). Its a thin synthetic canvas-like material on the outside, not unlike a durable rain jacket, and it's vinyl coated on the inside. The seam appears to be strong enough to handle repeated squeezing. Atho the metal tip is smaller than usual, it's small enough to get into tighter joints, especially if you flatten it a little on the end. All in all, as mason with 20+years experience, this is THE BEST grout bag I have used thus far. I hope this review helps.

Didn't work for the 1st project I had. Will use it on some upcoming tile work.

If you do this work that requires constant use then yes it is good quality, I found it to be rather messy, only one size nozzle so it was limited, the item worked as advertised.

The bag itself is very strong and relatively easy to handle. We used rapid set mortar which set hard in the metal nozzle within seconds. I tried it without the metal nozzle and it is much easier to use, the mortar doesn't set as quickly, and I can easily get the tip of the bag in between bricks without the metal tip.

I put in a rock mantle for my wood stove and used this grout bag to fill in grout in between the rocks. Easy to fill, easy to clean and easy to use. Highly recommend this for anybody that needs to fill grout in odd shaped gaps. comes with a metal tip that makes directing the grout where you need it to go effortless.

If you're hands are big enough it can hold a huge amount. Worked well.
