sanded or unsanded grout

I am grouting a tub surround,can I use sanded grout on spacings less than 1/8"? I used it on the floor (spectralock grout) very expensive and sets up way to fast but looks great.

Use unsanded grout mortar for grout joints 1/8" or smaller. Use sanded grout mortar for grout joints larger than 1/8". Sanded grout is used for most floor jobs, and unsanded for walls.

You'll have too much trouble pushing sanded grout into small gaps. Go with the unsanded.

Spectralock is epoxy grout and does not come in unsanded. If the joints are at least a 1/16" you'll be able to force the grout into the joints. If smaller than that, maybe not.

HJ has it right. The SpectraLock product is epoxy based and does not fall into all the same rules as a cement based grout does, mostly when the grout joint is narrow. It is expensive and is overkill on most floors unless there are specific situations to warrant its use.

Thanks for all the info. What are your thoughts on using a ceramic tile and fixture caulk by FlorCraft on the tub surround?

Are you suggesting that you will use caulk instead of grout on the walls. No don't do it. Caulk will not last nearly as long as grout and will look like crap in no time at all. As Tileguybob said, spectralock is expensive and you dont need to use it on your tub surround. Use regular non sanded grout and a good sealer. Thats all thats really required. You should however use caulk instead of grout for all joints where there is a change of plane (corners where 2 walls meet etc) and where the tile meets the tub.
