First thing first, you need some definite products to accomplish the job. Brace yourself because you will not need to provide much effort to gather the materials as they are some simple and easy-found essentials.

  1. A darker-shaded gel stain according to your preference
  2. Hand gloves
  3. A clean rag
  4. A lint-free rag or foam brush, or paintbrush

Step 2: Clean the Wood Trim:

You need to clean up the dust that the wood trim is carrying. You cannot just apply a gel stain right away on a surface without checking if needs cleaning or not. It is always better to wipe out the microscopic germs and dust from the surface before staining it with a damp rag. Otherwise, it cannot be detected by our bare eyes and you will face trouble regarding the adhesion ability of the surface.

Step 3: Stir the Stain:

As you want to re-stain your wood trim darker, bring a darker shade than the shade that is already on the wood trim. Then wear your hand gloves properly. They are important for your own safety. Then before opening up the container of stain, stir it very nicely. It will help the stain to restore its consistency which is one primal characteristic of a quality stain.

Now, it is time to apply a gel stain on your wood trim. You can use a lint-free cloth for this job of applying stain. However, a pain foam brush is more convenient so you can think of using it too. Dip the foam brush in the container of dark stain and then apply it to the wood trim. Go in the direction of the wood grain while staining. The first coat might still give a translucent color.

Step 5: Apply Second or Third Coat:

Because the first coat can hardly reach your desired color, you might have to apply a second coat and then a third coat. But before that, let the first coat dry properly then apply the second coat in the same manner as before. If it does not come up with the desired dark shade then prepare for the third coat.

But the third coat might darken your wood trim beyond your expectation level, so sand the trim before applying the third coat with fine-grit sandpaper. It will make the surface smooth and then lighten the color too so you can reach the desired dark shade by applying the third coat. So, apply the third coat in the same manner and thus you can meet your desired dark color on your wood trim.

Stripping and Refinishing Wood Trim:

Stripping and refinishing wood trim can be a long process. But the final look it provides is priceless. If your trim is still great in condition but you don’t like the color and it has dents, crevices, and scratches, then stripping the old paint and refinishing the wood trim is required. As it is kind of a long process and attention to detail is required, let’s get started with the process at once.

Step 1: Strip the Old Paint:

Scrapping is what old people suggest to strip old paint from wood trim. But there is a smart solution for this job and you can save up your energy by not scrapping old paint. Use Peel Away solution on your trim. It comes with paste on a paper. If you put it over the trim and let it rest for 24 hours straight, you will see the old paint coming off the wood trim.

Step 2: Clean the Trim:

Now you need to clean the trim with a great cleaning solution. Use a sponge or clean rag and scrub the surface of the trim properly. Denatured alcohol is good at cleaning stubborn dust from wood trim. Though it has abrasives, a little amount of it won’t affect your trim. After that, you need to roughen the surface in order to get a fine finishing. That’s why you need to use an abrasive synthetic finishing pad. This pad will roughen the space without removing the stain or creating any damage to the surface.

Step 3: Use Soft Wood Putty:

After roughening the surface a little bit, you need to take care of the nail holes, gauges, and crevices on the trim. Softwood putty works as a great filler. As there are various colors of wood putty available in the market, you need to choose the one that goes with the color of your trim. Fill the holes and dents with the filler and use your fingertips to wipe out the extra filler to make it plain to the surface of the wood trim.

Step 4: Apply Stain Properly:

Now you need to bring a stain that would match the color of the wood trim. After bringing the stain, apply it thoroughly to your wood trim. It will cover the scratches and uneven spots that happened by the filler at the same time. You can use a lint-free rag to apply the stain. Remember that, finding a matching stain is something very trickiest and when you find it, you give more than half the refinishing of the trim. Add a second or third coat in order to have the desired color and shade.

Step 5: Apply the Finishing:

Now to make your old wood trim look new again, do the last step by using polyurethane. This gives an amazing finishing to wooden trim. Use a rag and apply the polyurethane coat to the trim. Wipe-on polyurethane provides a shiny look to the surface. For more protection, you can give 2 or 3 coatings of polyurethane. For wood trims that are exposed to sunlight, use varnish over them for the final finishing. Thus, you can strip and refinish your wood trim and give them a new and fresh look again.
