Grain fillers are fairly easy to use but one thing does take a little skill and thought.
Wood grain filler before and after.
Sealing the wood prior to filling makes cleaning off the excess filler easier and is a good precaution when applying oil based filler to mahogany.
Grain filler can be tinted or stained before use if the bases are compatible.
Another option that s easier to work with is aquacoat wood grain filler it s almost a gel consistency so it s easier to work with and work it into the grain.
This time i wipe off the excess before letting the surface dry.
Since fillers are between putties and paint in terms of consistency they are fairly simple to apply when your ultimate goal is hiding wood grain before painting cabinets.
Most wood grain fillers won t take a stain very well after they dry.
And getting it right the first time is important.
Whatever color of filler you stuff into the grain of the wood will be a highly visible and permanent change.
To color only the pores requires removing the dried surface oil with more sanding.
Filling over sealer also lets you use colored filler to create contrast.
After the second slurrying all the grain should be filled the tinted oil in the slurry will have colored the entire wood surface.
Getting the color right.
In rare cases mahogany can absorb oil and turn the filler gray several months after the finish is cured.
The downside is that it takes more coats to fill in the grain so it s a trade off but it s definitely a product worth considering.
