Staining an Antique and Classic Wood Boat

Staining – It is the most important aspect of refinishing. Sometimes the hull and/or deck planks do not match color wise and special attention is needed prior to application of the filler stain to achieve a good overall color.

Pre-Staining

Quite often, new or replacement planks are lighter in color than the surrounding wood or original wood. Also, once the finish has been removed you can find big differences in wood colors from past plank replacement. Here are a couple of techniques that usually work for me.

If the color difference isn’t significant this 1st option sometimes will work: After sanding and fairing the area with 60 grit followed by 80 grit and no more than 100 grit, re-sand the lighter wood with 60 grit then stain the boat. The coarser sanding allows more of the filler stain into the grain resulting in a darker plank.

Often, the difference is too great for the first suggestion. Then we must get more aggressive with the coloring of the lighter plank. After sanding and fairing the area, tape off the lighter plank/wood. Now apply a coat of Minwax Red Oak #215.

This process is done using a chip brush and wiping off with an absorbent rag. Old t-shirts work well for this. The degree of darkening the wood is determined by length of time the stain is on before wiping off.

This is a rear deck king plank that was replaced. The new wood is much lighter and needs to be “aged” prior to filler stain being applied.

The new wood was taped off then stained with the MINWAX Red Oak Stain.

Immediately remove the tape and apply the filler stain. The colors will blend then. I like to refer to this technique as “instant aging”. Now finish as usual

Now the varnish is going on and you can’t tell the new wood from the original wood.

Applying Filler Stain

Mix the filler/stain to a consistency of a very thin paint. Apply to the wood with a brush or roller. I like to use a 6” roller and a 2″ or 3” chip brush. Spread the stain before it can dry by wiping with a plastic scraper.

This is what we have ready when we start staining. We always have a sanding block with 60 grit at hand to remove any scratches or swirl marks the appear when the stain is applied.

Hull side staining

A plastic scraper forces the stain into the grain and reduces the amount of waste. Bondo scrapers work well for this process. Follow this with burlap. First rub in a circular motion to fill in the grain, then using another piece of burlap finish rubbing with the grain. DO NOT ALLOW THE STAIN TO DRY BEFORE WIPING. It is helpful to have a spray bottle with paint thinner in it close by. If the stain is too thick or dries, spray some thinner on the burlap (NOT ON THE WOOD!!) and rub it out. Spraying thinner on the wood can cause runs.

Apply two coats of sealer then stain the darker wood. This way if any of the darker stain splatters onto the lighter stain it can be easily wiped off.

II. Sealing- Follow staining with at least two coats of sealer. I will LIGHTLY sand with 220 grit or a Scotch Brite pad. I just want to break down the gloss for adhesion with the next coat.

Sanding Hull Sides, Decks and Transom

A.) A random orbital sander with 80 to 100 grit is good for fairing the hull sides, decks, and transom. It also is good for sanding the new bungs flush after chipping them off with a chisel. Follow this sanding with 60, 80, maybe as high as 100 grit sanding by hand with the grain. Take your time and be sure to remove any swirl marks from the random orbital

sanding. A helpful hint is to LIGHTLY rub a pencil up and down (against the grain) the hull sides.

Then sand until the pencil lines are gone. This assures you of not missing any area of the wood.

B.) Another technique is to do all hand sanding of the hull sides, decks, and transom. This is good because it gives you time to inspect the wood very carefully as you work. After stripping, sand the entire boat with 60 grit, followed by 80 grit, maybe as high as 100 grit. As mentioned earlier, the pencil lines work well. When a plank has been replaced and is surrounded by old wood, do not sand the new wood beyond the 60 grit. This leaves the new wood with more open grain to hold the stain, resulting in a closer color match to surrounding old wood.

C.) Inline power sanding can also be used with the same 3 grits of sand paper.

 

 

 

 

 

 


D.) Be careful not to sand off the boot top markings.

 

E.) To keep residue from going into the bilge via the vent holes or any other large holes in the deck here is a good tip: Place a Styrofoam cup in the hole then trim the top to fit just below the deck surface. This will catch debris and is easy to replace.

F.) Tape joints to prevent cross-sanding scratches. These scratches may not be noticeable at this time but will be quite obvious when stain is being applied.

 

G.) Longboards are a big help when fairing the hull sides, decks and transom. I prefer the smaller one. Either one is available from Jamestown.

A smaller sanding block is easily made from a piece of 2×4, then glue a piece of Scotch Brite onto the bottom to act as a cushion

Now that the sanding of the hull sides, decks, and transom is completed it’s time to get ready to stain.

Bleaching Antique and Classic Boat Decks

A.) After stripping, sand the entire boat with 60 grit, followed by 80 grit, maybe as high as 100 grit.

 

B.) Now that the wood is ready for bleaching, tape off the area to be bleached.

 

C.) I prefer to do the bleaching and sealing before the dark stain is applied. Any splatters of the darker stain can be easily removed with paint thinner.

I use a two-part bleach after the last sanding.

The wood grain is clean and the dark areas are quite visible. At this time the grain is open to allow the bleach to penetrate deeper.

 

D.) Carefully mix the 2 parts and apply with a chip brush.

 

E.) After the area dries, gently sand with 120grit to remove the residue that oxidizes on the surface. Be sure to wear a mask when sanding after bleaching. More often than not, several applications of the bleach are necessary.

For those that want the rich amber color like Chris Craft’s often have, we then use Corina Blonde filler stain.

 

F.) After the stain dries overnight, we then seal the area with Interlux Interprime #1026.

 

G.) Now LIGHTLY sand with 320 grit and apply 1 coat of varnish.

 

H.) At this time we remove the tape and reverse the tape and stain procedure for the darker surrounding color. This way, any splatters of the darker stain is easily wiped off.

 

I.) After the other wood is stained, sealed, and 1 coat of varnish applied, now is the time I like to fill the deck seams.

 

J.) For blond decks like the Chris Craft Continental, fill the seams with
white Sikaflex 291 LOT.

 

As the varnish is applied, the Sikaflex turns amber in color and blends into the surrounding blond wood.

 

 

K.) After all varnish is applied the seams can be striped.
