Q: does Drylok work on the joint where the wall meets the floor

Christmas week 2015 I used this product knowing a forecasted 11 inch rain was on our way as was holiday company. I had a single vertical seem fracture that went down to the floor level. I made sure the wall and floor line was bone dry, lightly "V" chiseled and applied the product ALONG THE VERTICAL LINE AND THE ADJOING FLOOR LINE. The rains did come-- as forecasted-- the wall AND CONTIGUOUS FLOOR AREA held. Guests arrived, we had happy holidays and a dry basement from then up to the present day. Caution, I had used this product earlier on the same seam, still WET from an earlier rain, and it DID NOT HOLD. So my advice is to make sure it is VERY DRY before you apply.

Q: Can this product be used to reattached a loose veneer rock to outside of house

I don't think so. But Home Depot sells a tube of caulk for just this type of use. I have used it to reattach loose brick and slate. Sorry, I don't remember the name of it but you should be able to find on one of the aisles easily enough. It is for adhesive uses on concrete, etc.

Q: Can I use to repair cement laundry sink?

Probably depends on how bad the damage is. If it's just a crack it should be no problem. If it's larger than that I would use a screen mesh with the cement. That's what I did with my water fountain that had larger cracks.
