What happens here

If heavy sanding leads to 'burning through' the previous coatings and exposing bare wood, it's crucial to seal these areas before applying the final topcoat. A quick solution is to spray Zinsser Bulls Eye 1-2-3 Turbo Spray, a vinyl sealer, over the exposed wood. This prevents the raw wood from absorbing too much of the next coating and ensures an even finish. This sealer also acts as a barrier against contaminants that might cause 'fish-eye' issues during spraying. Having a clean work surface and a dust-free environment from the start helps prevent such problems.

Goal: If sanding exposes bare wood, seal it with a vinyl sealer. Also, use vinyl sealer or a shellac-based primer if contamination (like fish-eye) appears during the first coat to prevent further issues.

all right i'm continuing right along doing my sanding inspecting and i'm going to just give you a little tip there's sometimes occasionally well you'll burn into you know beyond your previous coating into wood the product that we're using the 2800 series product that we spray with it is a self-seal product sometimes you may have to add a third coat if you get into um sand into the wood pretty deeply and because it's going to absorb your coating and the first coat actually acts as a seal coat and then your next coat would be your top coat and so there's occasionally you might have to do a third coat you can just spray on a vinyl sealer cic has a vinyl sealer that you can seal this bare wood first before you do your top coat so i can just take these edges where i did burn in in there and just spray a vinyl sealer on here i'll do my final sand and make sure i don't cut through that and that will actually seal that bare wood so it's nice to have a can of vinyl sealer i also use the vinyl sealer for one when i spray my first coat if there's any contaminants on this door you can actually see it because it's gonna fish eye and the vinyl sealer or a shock bomb can works amazing for eliminating fish eyes so it resolves any type of contamination issues you may have in spraying cabinets i'm going to say i don't think there's ever been a cabinet job that i've ever done before in my career where one of the doors did not have a contaminant even after cleaning that even after sanding it that didn't fish eyes so having a can a vinyl sealer is an absolute must when doing cabinet doors so another part of flat
