Have started working with these water-based products and so far my experience has been great. Just did a job for a client who want to match the stain /colour of a factory-finished ash hardwood floor to unfinished ash stair treads and risers. It only took me four sample mixes to get close.
Am doing a solid oak bookcase for another client who wants it to match their bedroom suite. This time, three tries and nailed it.
The only downside is that I'm working in 35C temps and low humidity, so it's drying a little too fast on larger surfaces to rub the excess off, but using a damp cloth instead of a dry one seems to solve the problem.
I have had one can of sanding sealer that was jello rather than liquid, but I just took it back to LV on my next visit. Customer service reply from GF was less than 4 hours after I sent a query about the problem.
All in all, very nice products.
