How does wood stain protect wood?

While staining creates a rich, deep color that highlights natural wood grain, it does not provide long-term protection. Without a protective top coat, wood can be damaged easily due to contact with water, food, or sharp objects. A polyurethane top coat protects the wood from scratches, stains and water damage.

Method 2 Using Sealants to Waterproof
  1. Prepare the surface. You'll need to remove any remaining trace of past finish before using a sealant.
  2. Purchase a water-based wood sealer.
  3. Apply an even coat.
  4. Allow the product to dry.
  5. Clean the first coat.
  6. Apply a second and third coat.
  7. Give the wood time to cure.
  • Is the wood waterproof?

    The wood was a tricky one, as the water didn't pass straight through the wood to the floor of our house, but was absorbed by the wood, so it wasn't waterproof. The plastic was clearly waterproof, you can see here how the water beads on the surface.
  • What can I use as a wood sealer?

    A sealer coat (sometimes called "wash coat") is often used over the stain or on unstained wood. Its purpose is to "seal" the pores of the wood to give you a smooth, even surface for the top coats of varnish or lacquer. The sealer coat will also prevent the stain from bleeding into successive coats of finish materials.
  • Can you use untreated wood outside if you stain it?

    Even though natural weather-resistant wood is the best choice for outdoor exposure, at some point it becomes vulnerable to decay. The only way to properly use untreated wood of any type outside is with the addition of water-repellent preservatives, sealer or paint that contain UV protection.
B.

Is there a waterproof varnish?

With water-based polyurethane, cleanup is a snap with soap and water. Varnish, a combination of resin, solvent, and drying oil, gives a hard-shell finish that resists scratches without yellowing. To waterproof wood that will be placed outdoors, choose marine varnish, which contains UV absorbers to resist sun damage.

  • How do you seal wood naturally?

    Here are the basics:
    1. Step 1: Clean/Prep. Make sure your wood is sanded, dry and free of dust and debris.
    2. Step 2: Apply Tung Oil with a Natural Bristle Brush.
    3. Step 3: Wait, then Re-Oil.
    4. Step 4: Remove any Excess Oil.
    5. Step 5: Add one More Coat (the next day)
  • Is varnish the same as polyurethane?

    The ravages of time and use of a piece of furniture can be limited by a durable top or finish coat. While the terms varnish, polyurethane, lacquer and shellac are commonly used to reference a final finish in general, these products are not the same, nor are they recommended to be used interchangeably.
C.

What does a wood stain do?

Stain may be loosely defined as any transparent or translucent agent used to color wood. Unlike paint, which has pigment suspended in a binder, the coloring agent in stain is a dye that is dissolved in liquid. Thus, the color penetrates into the wood fibers, rather than resting in a surface film like paint.

  • Is varnish and stain the same thing?

    Wood stains are absorbed by the wood and mimic the color of a particular species of wood. (This could be the same type of wood you're using or a completely different species, depending on your preference.) Varnish is a clear, transparent coating that lays on top of the wood.
  • Do you need to seal wood stain?

    Most stains should be sealed to prevent bleeding. After smoothing the stained wood, apply a sealer coat of thinned shellac, sanding sealer, or other appropriate sealer. Do not use shellac with NGR or water-base stains. If you plan to finish the piece with polyurethane, make sure the sealer is compatible.
