## Questions & Answers

A: Yes stainless steel ( no rust )

A: Made in Spain

**Q: Is this 2 trowels like the picture implies or is this one trowel as stated in the description? Im guessing the seller is to lazy to use an accurate p**
A: The price reflects one trowel. I purchased the 1/8 X 1/8 to install the membrane and it worked well. I would suggest using a sheetrock trowel to smooth out the membrane once you apply it to the wall. There are a number of great you tube videos illustrating the proper technique.

A: Yes its Stainless steel trowel, supposed to be rust resistant

### ⭐⭐⭐⭐⭐ Excellent tool for sealing

This worked great to spread the right amount of mud under the sealant strips. Great tool!

### ⭐⭐⭐⭐⭐ Schluter is quite proud of these
*by E***R on May 30, 2024*

I lay a lot of their product in my home and I was pretty annoyed at the recommendation to buy all their trowels for all kinds of different applications, and they sure aren't cheap. BUT...they are a very good quality product and when you're dropping the big big big bucks for Kerdie board and ditra, you want the right tools so I'm going to vote "yes' on these. They are super well made and not a speck of rust to be seen. So, a good product priced like all their others.
