CV & 3M8/28
We do some top finishing and I switched back to ML Campbell - Krystal. I like it and I am familiar with it. Several questions. I have used several sealers, Krystal sealer and most recently level sealer. I have had nice results with the 3M buffing system but never used it on Krystal. Does it work well on Krystal?
A major problem for me at this time of year is it's darned hot in the finish area. Had good luck with thinning typical finishes but not overly familiar with thinning Krystal. Specifically to slow the drying time and allow the finish to flow out. Last week I did a small top and got some fan marks where the stuff was drying so darned fast.
We use #1 and #2 flow enhancers as well as care reduced to slow drying because it's so darned hot right now. We all ready spray in the evening and that helps some. I am considering upswing a retarder. Don't have much experience with that product. Anyone have any suggestions? Will the retarded leave the finish open too long and allow bits to settle into it? We can buff them out I just want to be prepared.
Thanks and hope everyone is doing well.
I would expect that flow enhancer #2 slows down the product enough for you, i wouldnt use a retarder not specified from MLC, as their products are pretty finicky as it is.
In terms of buffing, once krystal reaches an appropriate hardness, it should buff out problem free, give it atleast 48 hrs before you try to buff it.
I've heard from many people at MLC that Level Sealer, and Level Primer are two of the worst products that MLC makes. It's definitely had its issues over the last few years. I would never trust it. If you need such high build, go with a polyester/2K finishing system. Tried, true, and incredibly durable. Otherwise, krystal sealer dries quick, and sands very well.
Even with flow enhancer #2, the flash off time should be <30 min, so as long as you have a clean booth, you shouldn't have many issues with things settling on the finish.
Thank uTyler very kid d to reply. I have had issues with level sealer but to not know of another dealer with such high build. We use it a lot to fill grain and such. Any suggestions
Chemcraft makes a polyester sealer.
It's a difficult process, and generally requires two guys for the system to run smoothly, but once you get all of that hashed out, it cannot be beat. plus, a 2k poly is a better finish for table tops, and polishes better than CV.
