Topic tags/keywords: sapele table top

I finished my glue up on my 1 inch thick Sapele and took my table top to a local shop that ran the whole top thru an an 80 grit drum sander. A current picture is above. My plan for finishing is below. Any feedback will be appreciated. Plan:

1) sand the top to 150 grit as recommended by arm r Seal website.
2) add a coat of arm r Seal to bottom. Wait 4 hours flip coat the top. Wait 24 hours. Then add 3 lite coats of aqua coat following recommended dry times.
3) sand with fine sandpaper (320 or finer) and and 2 more coats of arm r Seal with 24 hour dry times.

4) allow 30 days to cure as recommended

Question:
Which Aqua Coat product are you using? Filler, sanding sealer, top coat?
They have many, and some use different chemistry that would change any recommendations we might make.

I think you’re good. The one comment I have is that I don’t think 2 coats of ATS is sfficient for a table top, it just doesn’t have the film thickness needed. Maybe consider a few more coats.

+1 Number of Arm-R-Seal (ARS) top coats on table depends on application method, and desired results.
Two may not be enough?

- With a perfectly flat surface you can brush on thicker layer of ARS than can vertical surfaces, so fewer coats can be used. Wiping on ARS leaves a much thinner film than brushing, so you need more coats.
- With grain properly filled, 2 brush coats, or 3-6 wiped coats should be good protection. Applying much more on smooth surface tends to get a thick plastic look on wood.

Tips on brushing ARS.
- Don’t attempt to rebrush an area after it has set for a few minutes. It leaves streaks, and/or impressions.
- ARS creates runs easily with thick film. It tends to create drips on bottom side edges, as the vertical sides won’t hold as thick of a film as top. They are sneaky. About 5-10 minutes after you finish coating top, walk around and wipe off the bottom edges to remove the inevitable drips. Have seen ARS migrate under the tacky skin, and create drips up to an hour after application, despite previous removal of initial drips.
- If you find dried drips/runs, use a nib file to remove them after ARS has cured at least 24 hours or more. Filing them down doesn’t impact large area like sanding, and 95% of time can buff out the defect without any sanding. Worst case, wipe a very thin coat of ARS to hide filing marks.

Cheers!
