I haven't paid close enough attention over time to the uneven slabs, so I can't say for 100% sure whether or not they move with the transition of seasons. All I can say is that it's not noticeably different, so if it does move - I THINK it's minimal. I really don't want to monitor the movement for an extended period of time...
Given where I'm located, would I get more votes to "honor" the joints? I'd hate to have to, in the long run, continually replace cracked tiles between seasons. Would it be advisable to treat each slab section as it's own tile install? And if so, would I then be better off using Sikaflex or a similar product for those tile joints that follow the slab joints?
I've seen lots of comments about Legacy Industrial's HD-821 and wondering if that would be highly recommended for my garage?
Oh - quick note about the floor drain grate. There aren't any visible screws holding it down, and I can't imagine the whole cover is a screw type. That just doesn't make sense to me that it would be designed that way taking into consideration where it's used.
I would image some of you out there who install floor coverings have come across hard to remove floor drain grates. Can any of you comment on experiences and how they were removed?
I have no input on that drain, other than apply a healthy dose of muscle. First check it is somehow mechanically attached, then got at it with some tools.
As far as the joints. I have to be honest with you. I didn't honer any of them. I figured it this way. If someday the joint cracks, I will replace that row, and then honor the joint. So far I have had no issues. It's not like you need to color match some paint sample or something to have it looking new again. Chip out old tile, and replace.
