Can you stain wet wood?

Staining wood can be a great way to add color and protection to it, but what happens if the wood is still wet? Can you stain wet wood, or will the stain not take properly? In this blog post, we’ll explore whether or not you can stain wet wood and how to go about doing it correctly. Read on to learn more!

What is wet wood and why would you want to stain it?

Wet wood is just that – wet. While the best time to stain wood is when it’s dry, wet wood can still be stained depending on what kind of product you’re using. By far the most common type of stain used to color wood is oil-based varnish or paint. These types of products are known as either being “wood conditioners” or “topical finishes.”

Topical finishes are designed specifically for use on bare wood and while they don’t soak into the surface like a pure oil does, they will adhere to the outer layer where the water has evaporated over time (water creates an invisible barrier). If staining wet wood, it usually takes several days for this to occur naturally (of course, you can expedite the process by drying it with a fan).

Another key thing to know when staining wet wood is that oil-based finishes are not water-soluble. So, before even beginning the staining process, be sure to remove any excess moisture from the surface of the lumber using a shop towel or rag. This will help ensure that the stain takes evenly and without running or smearing afterwards.

The different types of stains that are available

There are several different types of stains on the market, which differ in their composition. Most stains fall into one of three categories:

Water-soluble stains Oil/urethane hybrid stains Oil-based stains

As you might have guessed, it’s possible to stain wet wood using water-soluble and oil/urethane hybrid stains. However, oil-based stains are out since they’re not soluble in water (and can’t form a bond with wood that has any moisture on its surface).

Can you stain wet wood:

No, you cannot stain wet wood.  If you try to put any type of stain on wood when it is still wet, the water in the wood will dilute the stain and cause blotches or uneven coloring. You must let the wood dry completely before applying any finish, paint, or stain.

A big part of choosing which type of exterior paint to use (latex vs oil-based) depends on whether your siding is bare wood or already painted.  Oil-based paints work best for bare wood but if your house is already painted in latex then it’s recommended that you use a water-based paint instead because latex will not adhere well to an existing coat of latex paint .

The same principle applies with staining – if you try to stain bare wood, it will absorb the stain unevenly leaving blotchy areas.  For even coloring and professional-looking results, always let your siding dry for at least 48 hours before staining.

The benefits of staining wet wood:

  • The benefits of staining wet wood are definitely not worth the risk.  There are only two reasons for wanting to stain wet wood:
  • 1) You want to change the color of your house, but don’t want to wait until it’s dry.
  • 2) If you absolutely MUST stain your newly painted or bare siding while it is wet/damp, then be sure that you use a 100% acrylic exterior stain.

The potential drawbacks of staining wet wood:

The potential drawbacks of staining wet wood are very serious and could result in you having to completely strip off any previous stain and start over.

 Staining wet wood can cause:

1) Blotchy or uneven coloring:

The water in the siding will dilute your stain, leaving blotches or uneven coloring. The blotchiness can be especially noticeable when trying to achieve an opaque color.

2) Bubbling:

Staining wet wood can cause the finish to bubble up where you don’t want it bubbling up (aka buckling). The areas underneath the bubbled-up paint will now be open for moisture penetration and potential rot.

3) Flaking:

If the existing coat of paint on your house is latex, staining it while it’s still wet could lead to peeling and flaking issues because latex does not adhere well to other layers that are also latex. So what starts out as one small area where your fresh stain gets speckled with peeling paint will quickly turn into a bigger problem as the areas of peeling and flaking grow.

4) Blistering:

Blistering is also another common issue when staining wet wood, but may not always be visible right away. Over time all those bubbles from buckling and blistering can create small pockets which trap moisture underneath them creating ideal conditions for rot.

5) Stain bleeding through:

If your siding is cedar or redwood, you should know that these woods naturally contain tannin which can cause bleeding issues if stained while still wet/damp. These woods tend to absorb stain unevenly leaving blotches or streaks where the natural tannin in the wood comes to the surface.

So now that you know the possible drawbacks of staining wet wood, hopefully you will think twice before staining wet wood.
