Orange Peel In Finish

Traditions2

I've done quite a few countertops now. My one problem I keep having is getting orange peel in my finish. I know I need proper air and not too thick of coating. However, here lies my problem. The product I use for the stone look is called multistone. When sprayed it has a definite texture. I sand that down with about 600 grit paper before clearing. However, there is still texture. If I sand the multistone too far it gets into the primer. When I spray multiple layers of thin clear you can still see the "hills and valleys" of the multistone. If I put it on nice and heavy it does cover the texture but leaves orange peel. My latest thought is to apply the first two coats heavy to cover the texture. Then wetsand the orange peel out and spray a final light coat on top. The only problem is then i have an extra day on the job. What do you think? ANy suggestions? I attached a pic of one of the countertops. Hard to see the orange peel in the pic. It wasn't too bad on this one.

What about sanding between all of the clear coats? Achieve the look of a Ferrari finish!

That would be ideal. Problem is there is a texture from the multistone and it needs to be built up pretty heavy.

If this job was better than the others what did you do differently with this one to achieve a more desirable finish? Maybe a couple of high build coats with a few clear coats on top of that using a different type of material?
Sanding between the final clear coats of course.

On your last coat use a retarder, a strong one. It will keep the coating open longer and allow it to flow out to a smoother finish. That is how I do it with lacquer products. Put it on a little heavier. Just be careful you don't put it on to thick, if it skins over before it gasses off you will get micro bubbles from the remaining gassing off. At least that is the way with the lacquers I use. Never used your product. Don't even know if there is a retarder or what the open time is.

Traditions2,
After looking at their web site, it looks to me like your first coats aren't drying all the way before the top coats.

If the early coats aren't all the way dry, waterborne finishes can shrink down considerably & give an orange peal result. It says in the instructions to wait 12 hrs before top coating. The only way I know to speed it up would be to apply heat, especially in the the early coats. We have used brooding lamps, & quartz heaters in cold weather in our shop booth with waterbounes. Sometimes you can use fans, but you have to be carefull not to skin the finish over too fast. I would think the primer, & texture portion would be fairly porous, & would benefit from fan drying, but I'd check with the manufaturer first.

It looks like a prety nice product!
