Hi All,

Cheers

when i used a dewalt - no speed swtiches but speed via the on finger pull button , i start of very slow and make sure its not going to slip and mark the tiles

I have a rotary dial thing 1 - 6. So should I start at minimum and build to max?

Sounds sensible. If you need to speed it up at all. Slower may be safer from slipping point of view

Thanks. Wasn't sure whether faster speed means clears the grout quicker or not.

At the lowest speed possible to do what you need it to do

I have only used my multitool to remove grout a few times. Low speed was useless- it resulted in a lot of vibration. In each case the tiles were ceramic so I had to watch out for the glazed edges of the tiles. I found that 50-70% speed worked best for me. I tried to stay in the middle of the grout line and then used a hand rake to clean the edges of the tiles.

Be advised that it is a painfully slow process, and very dusty.

If I had to do a larger area, I might consider using an angle grinder but I guess it might be more difficult to control- and it would be much more dusty.
