Staining and finishing wood can make such a fun project. There's
just something about creating something yourself - all the hard
work, the personalization, the sigh of relief when it's all over.
You know what we're talking about. And we love the entire process.
So get your gloves and follow along to learn how to stain like a
pro, because no one has time for mistakes.
There are three main parts in the finishing process
- Assembly and Preparation
- Applying Color
- Top coating
Mistakes happen commonly during all three of these phases and
the best advice we can offer you is this: practice, practice,
practice! Also have a piece of scrap wood to practice on. The worst
thing that can happen is when you go in blind and the stain is the
complete wrong color, or it wasn't mixed properly, or it's much
thinner/thicker than you anticipated. Please avoid the utter
disappointment that results from not practicing. Pick up a piece of
scrap wood and test out everything you use.
Let's get into it, shall we?
Here are 10 common mistakes made when finishing and how to avoid
them.
1. Scratches from sanding and cutting
Using the wrong grit sandpaper or the wrong sanding method
is a great way to start off your project on the wrong foot. Avoid
this common mistake by double checking the type of wood you have
and making sure you have the correct sandpaper to use with it. If
you go to apply the stain and you can already see scratches, stop
what you're doing. Start with a new piece of sand paper and start
sanding again, frequently changing the paper. Then reapply the
stain carefully to match the surrounding area.
2. Sand-Through
Sand-through happens when you just get way into sanding your
piece. You've gone though some veneer, most likely on an expensive
piece of plywood. There's no reason to panic. This is what your
scrap wood is for. Take the extra piece and create the same effect,
sanding past the veneer. You can choose to use stain or Blendal
Powder to fix the blemish, bringing back the original color.
After it's dry, continue with your normal staining
process.
3. Glue Residue
Using too much glue can cause it to drip everywhere, ooze out of
joints, and leave smudgy fingerprints on your wood. Oils and stains
won't cover up this residue, which would leave an ugly blemish on
your piece. If you have small smudgy fingerprints, just use
sandpaper to lightly sand these away. If you have bigger globs or
drips that can't be easily sanded, use a chisel or putty knife to
carefully scrape the excess glue off. Then sand the area to make
sure the surface is smooth.
4. Uneven Dye Stain
Often times, dye based stains end up more
concentrated in certain areas. If this happend to you take a damp
rag and gently wipe away at the area. The Rag will pick up some of
the dye, hopefully evening out the color. Then reapply the
stain.
5. Choosing the Wrong Stain Color
This is why we say practice, practice, practice! Always test out
your stain before using it on a bigger project. You just need to
test a small section on either a scrap piece of the same wood or in
a spot that won't be visible on your main piece. In the sad
scenario where you didn't test your stain and the color ends up all
wrong, you have a few options. You can put in some elbow grease and
attempt to sand off the stain you applied. Or you can apply a glaze
in a contrasting color, which will tone down the color of the
stain.
6. Blotchy Stain
Some stains don't take evenly on certain woods like pine and
cherry. If the situation is severe and there are many, big blotches
you'll have to sand or strip and start from the beginning. If the
botches are minor you can once again use a glaze to try and offset
the colors.
7. Drips
When the stain starts to drip down the side of your piece, don't
be tempted to stop it with your finger. This could end up smudging
the area. Instead, wait until it's completely dry and lightly sand
the area until it is smooth. Don't sand comepletely through the
stain - just enough to even out the drip. if you're tired of
sanding, you could use a razor blade to gently scrape off the built
up stain.
8. Contaminated Finish
When you go to put on your stain or coating and it acts in a
weird way, it may be contaminated. The most common signs are when
the stain doesn't apply easily or if it moves in a weird formation
once applied, congregating in the same spot. This often happens
when mixing water and oil bases. To fix this, wipe off the stain
that you already applied. Then spray a thin coat of shellac on your
project to provide a protective layer. Shellac will also prevent
contaminants on previous layers from rising to the surface. Once
dry, apply your non-contaminated finish.
9. Burn-Through
Burn-through is similar to sand-through, expect it means you
went through both the stain AND the top coat. If this happens,
carefully apply more of the stain to the area trying to blend it
in. Then add your topcoat once again. When the area is dry, rub it
out to blend it in.
10. Witness Lines
Can you see a definite difference where two products were not
applied evenly? If you notice this, keep leveling the finish and
then apply at least two more coats.
