how to fix wood filler spots?

If you have ever painted your walls and noticed that it looks like there are parts of the paint missing or splotchy, then you’ve likely got some wood filler showing through.

Wood filler is a great product for making holes in your walls look better and keep them from being an eyesore.

However, if you don’t cover wood filler up properly with stain or paint, then it’ll show through to the other side and make things look even worse than they were before!

How do you cover up wood filler stains?

There are several ways to cover up wood filler spots, but your best bet is to choose a stain that matches the original wood’s color.

In addition to matching your existing piece of furniture, this ensures that any new repairs will blend in seamlessly with the rest of it.

If there are multiple stains on board, you may need to do some experimenting with different combinations before settling on one.

One option is to use a stain-and-varnish combination; these two products can be used together as long as they have compatible drying times (the varnish should be dry before applying another coat).

You can also use a stain-and-polyurethane combination—the polyurethane will help seal out moisture from underlying layers and protect them from damage caused by water penetration over time–or even apply two coats of lacquer for extra durability against moisture exposure.

Why is wood filler showing through stain?

There are a few reasons why the wood filler might show through on your project, but the most common cause is that you didn’t apply enough stain to your piece of furniture.

When you’re applying stain to a piece of wood, it’s important to remember that it needs time to soak into the pores of the wood before it can really be considered “set.”

If you’re not sure how much stain your product should actually absorb, there are several ways to test this.

First, take a small amount of water (a drop or two from an eyedropper) and apply it directly onto a piece of scrap wood.

Wait for about 10-15 minutes and then wipe off any excess water with a clean cloth; if your test area has dried completely without leaving any wet spots behind then you know that enough heat has been transferred in order for the particular brand of stain used in question (or even just basic watercolors).

Can I sand and stain wood filler?

Yes, you can sand and stain wood filler.

To make sure the wood filler is smooth and flat, sand with fine-grit sandpaper. You’ll need to use a tack cloth or wiping cloth to remove any dust from the surface before staining.

You’ll want to use a stain that matches the color of your existing wood, or at least comes close enough so that it won’t be noticeable once dry.

When choosing a stain, keep in mind that there are two types: oil-based and water-based. Oil-based stains are more durable but require more effort when applying them because they’re difficult to clean up (and thus may cause additional damage).

Water-based stains are easier to apply but aren’t as durable as oil-based ones, though they’re also less toxic than their oil counterparts—which makes them preferable for projects involving small children or pets and/or frequent use areas like kitchens or bathrooms.

Also consider whether your project requires top coats (usually clear), which help protect against scratching and UV rays from sunlight; top coats can also change how much color shows through on some wood surfaces so be sure to choose one that works with whatever look you’re going for!

How do you smooth out wood filler?

Once the wood filler has dried and cured, you can then sand it down using a sanding block. A metal scraper will also help remove any excess that you might have left on the surface of your table.

If you don’t have a scraper, try using a steel wool pad to smooth out your wood filler once it’s been applied in all areas. You can also use a putty knife to smooth out any rough spots on the surface of your table if needed.

How do you make wood filler look natural?

The first step to making wood filler look natural is to use a natural wood filler. The next step is to choose a stain that matches the existing wood or one that contrasts with it.

To make sure your filler blends in seamlessly, you have several choices:

  • Choose a stain that matches the existing color of your wood. This can be done by choosing a stain that is darker or lighter than the original color of your piece of furniture. For instance, if you have an oak table and want to fill cracks in its top with putty, consider using mahogany putty instead of oak putty because it’s lighter in color than oak (and therefore won’t stand out).
  • Choose a different type of fill material altogether—such as sawdust or sawdust mixed with glue—to create something unique and interesting!

Does varnish cover wood filler?

Varnish is not only your best friend when it comes to filling in gaps, cracks, holes, and dents; it also works wonders on wood filler. In fact, you can use varnish to hide the effect of wood filler completely in some cases.

Here’s what you’ll need:

  • Varnish (multiple coats)

How do you blend wood filler?

  • Use a putty knife to blend the wood filler.
  • Use a sanding block to smooth the wood filler and remove any rough edges.
  • Wipe off excess stain with a damp rag, then wipe it dry. You can also use a dry rag to wipe off excess stain, but I find that this tends to leave an uneven finish if the surface is not completely dry first.

How do you fix a blotchy stain?

If you have a blotchy stain, it’s possible that using a stain that matches the wood will fix your problem. If the stain isn’t matching, then try using one that is darker or lighter than your current color scheme.


The most important thing to remember is that the only way to fix wood filler is with more wood filler. So if you’re looking to cover up a spot that you’ve just filled, it can be done!

Just mix up some more of your favorite stain and apply it over the filled area. You may need some sanding in between coats, but we think it’s worth it for all the benefits that come with using this product (like how easy it is to use).
