Seal coat for tinted WB Lacquer

[Russell Tribby]

I'm going to be spraying some cabinet doors and a face frame with a tinted WB lacquer. The doors are maple and I wanted to use a seal coat in order to try and avoid blotching when I lay down the tinted lacquer. Should I just spray a coat of clear WB lacquer before I put on the tinted or is there a better option?

shellac is always a good option for sealing.

A clear coat of the same product you are using is certainly a good option...stay with the same product for best results, however.

Using de-waxed shellac is what I typically do, as it has less grain raise.

Lacquer on top of lacquer will "remelt" into itself. I'm not sure it that is better (better in terms of what, I'm not sure: appearance? longevity? ??) but it is what happens.

That said, I've never had any issues with shellac (dewaxed or not) as it is the all-purpose binder of varying finishes and is a great sealer.

Thanks for the replies. I went to the supply store this morning and found out that the same company (Trinity) that manufactures the WB lacquer also has a WB sealer. I decided to give that a shot. I'll post the results when I get done. Thanks again.

You would be better off using the wb sanding sealer than the shellac. Using water born products over shellac will some times produce a milky haze under the lacquer that will not go away. The sanding sealer is ment for your first coats a little more solids for filling in and easier to rub out for your finish coats. Tinting will go well over the sealer.

Thanks Tom. That's good to know. I don't have a lot of experience with using the WB lacquer or with using a tinted version of it. I'll post some pics of the doors when they're done.

True for solvent based lacquer but not always for the waterborne acrylic lacquer the original poster is using.

I have never had this happen using de-waxed shellac (Usually Zinsser SealCoat for convenience) under Target Coatings water borne finishes. And the shellac reduces grain raising considerably over a water borne product. That said, one should follow the manufacturer's recommendations for any "sealer" used under a particular finish to insure compatibility. All water borne products are acrylics, but some have special properties, such as true burn in. (Target USL is an example of that)
