Sanding Sealer Compatibility
Question
Forum Responses
From contributor B: I use Targets CV and find that you need spray a lighter coat. This keeps the dry time down and results in a better job. From the original questioner: Maybe I didn't phrase that correctly. The CV is fine - it was Target’s 8800 universal sealer that was too slow. 1-2 hours before sanding is much slower than what I'm used to with the Enduro sanding sealer. 20-30 minutes is common to sand the Enduro sealer. I was just concerned about crossing manufacturer’s WB products. I've done two samples using the Enduro as a sealer and then final coating with Targets CV and both seem fine. Also the viscosity of the universal sealer makes it painfully slow to load into my gravity gun. From contributor C: I have a stupid cabinetmaker question for you finishing gurus - why exactly to you need to use a sanding sealer? Is it just to make sanding out the first coat easier? I spray the Target USL product directly on my furniture and cabinetry and get what I think are good results. It also dries pretty quickly. I personally can't take the smell of the Enduro products. I don't have a spray booth and the smell seems to linger for a long time. From contributor D: USL is self-sealing so you really don't need a sanding sealer with it. The finish is superb, in my opinion. I've noticed another thing with the USL that's pretty cool. If you spray it over dewaxed shellac, there's virtually no sanding required. I use a 5% solids mix of shellac as a washcoat on blotch prone woods and use it full strength as a barrier coat over and under glazes. The USL goes on glass smooth in both cases. From contributor E: One reason to use the WB shellac sanding sealer is if you have any concerns about contamination. I am finishing a Mahogany c-top right now and sanded the top to 220 grit and the end grain to 600 grit per the Target Rep’s recommendation. Normally I rarely would touch 220 grit paper. Having one of my typical "oops" moments I used stearate paper for the 600 grit. Now I am using the shellac to seal in any possible contamination before topcoating. The rep also told me that the shellac product would reduce the chances of "pinholing" on a mahogany slab. One other reason for using the sealer is that WB products will raise the grain. The sanding sealers (which are usually fast-drying) allow you to spray a first coat and then sand off the fuzz before topcoating. I have not tried Target’s universal sealer yet but the M.L. Campbell sealer dries very fast. It seams like you should be able to spray the CV over another company’s product, but I couldn't say for sure.
From contributor F: I, too, like Enduro sanding sealer but am chucking their poly - I've had nothing but trouble with it. I'm going to give Target's lacquer a try and would be interested in whether or not it performs well over Enduro sealer. Would you like to add information to this article?
