Sanding between coats???
Ok this is my first furniture piece so forgive my ignorance. I made
a kitchen island out of cherry and finished it with Olympic oil based "Natural" stain (pretty much a clear stain)and then put on my first coat of polyurethane. I am going to let that dry overnite, but I hear several instructions on "sanding between coats". Does this mean sanding with an orbital sander with what grit paper? something like 600 grit? Also how many coats of polyurethane should I use? thanks!! |

It means light hand sanding with 220 or thereabouts. NOT power sanding.
If applied in typical fashion (thickness), three coats is typical (assuming you aren't thinning the finish much). David wrote: Ok this is my first furniture piece so forgive my ignorance.

I tend to use 320 more often than 220, as I spray water borne urethane,
instead of poly. You can recoat poly under "normal" conditions in less than 3-5 hours, btw. David David wrote: It means light hand sanding with 220 or thereabouts. NOT power sanding.

Since poly does not normally go on with additional coats being applied over tacked coats - you put coats on over dried coats, you will want to simply scruff the surface for adhesion and smooth spreading. Steel wool, 3M pads or sandpaper ranging from around 320 grit on up will work. All you are looking to do is break the glaze on the dried coat for the new coat to adhere to. While you're at it, know down any dust nibs. If you're spraying it then experiment with spraying additional coats over tacked up coats. Obviously, you would not sand between coats since the tacked up coats will not sand very well. Smear would be more like it. I've had mixed success with spraying poly so I generally just brush it with a light rub down between coats. -- -Mike- |

Hand sand between coats. I use 220 grit and move to a higher # for
the next sanding. The purpose is to remove any bumps and to provide a little "bite" for the next coat of poly. Two or 3 coats is about right. Follow the manufacturer's suggestions.

Well, to me, the most important information has been omitted - tack the
bugger off well after scuffing or you'll be reattaching sanding dust. I like 400 wet/dry on a block so it levels and scuffs, lubed by mineral spirits for a consistent bite. wrote in message ...

On most of the can of Poly it says to re-coat within a 2 hour time frame.
More importantly, it also states that if you miss that window, you have to wait 72 hours before sanding and recoating. I wait the 72 hours, sand with 400 - 600 wet using mineral sprits as a lubricant, dry, wipe with a clean lint-free towel dampened with mineral sprits let dry then re-coat. I probably would not go to that much trouble for a kitchen cabinet however. I would put on two or three coats all within the 2 hour time frame. Let dry for a few days, touch up bad areas with 600 or 000 steel wool and spray(can) recoat. Dave wrote in message ... Ok this is my first furniture piece so forgive my ignorance.

72 hours between coats, huh? You've got a LOT more patience than yours
truly! I'm chomping at the bit after 2 hours to get the next coat on (waterborne), or 3-4 hours when using poly (ugh).

David,
That's what the can says - even the waterborne poly. Dave "David" wrote in message ... 72 hours between coats, huh? You've got a LOT more patience than yours truly!

My waterborne poly's don't suggest waiting 3 days between coats! Au
contraire! Recoat time as stated on Compliant Spray's site as: " Drying Time: Dust free in 3-8 minutes @ (65° to 85°). Sandable for recoat in 20 to 30 minutes. May be force dried after flow-out.

David,
The point was, read the instructions. The poly I used on the last project said wait 72 hours before sanding. If the OP (or anyone else reading this post) was using Minwax Spray Poly, then sanding after only a few hours would raise havoc with their project. AAMOF - really a fact or just your humble opinion. IMHO, Minwax makes a good product for many applications. I will grant you there are better ones out there and I have used many of them. The use drives my decision on the product choice. Dave "David" wrote in message ... Why on earth are you quoting Minwhacks??? No where did I mention my application of Minwhacks products. I HATE Minwhacks, AAMOF. Most other mfgrs produce superior finishes and stains. |

I've sprayed Minwhacks and had no problem sanding after 3 1/2 to 4
hours...but I reserve my right to use non-Minwhacks products from now on. As to the "AAMOF" that you mention, I was stating an absolute "FACT"; that I hate their products. That is not opinion, nor subject to interpretation, or spin by you. My last comment about other products was, indeed, my humble "opinion".
