Different Types Of Stains:
There’s no need to be stain-phobic! In fact, sanding between coats of stain can actually help to clean and remove the stain. Different stains require different cleaning methods, so it’s important to understand the type of stain before getting started.
Here are some important steps:
- Test a small area first to make sure the stain will come out.
- For grease-based stains, use dish detergent and warm water (or cool water if the stain is fresh).
- For water-based stains, use a paste made from baking soda and vinegar or white vinegar.
- For oil-based stains, use mineral spirits or lacquer thinner mixed with ammonia (available at most hardware stores).
Steps One- Use A 220/240 Grit Sandpaper
First, take sandpaper around 220 or 240 grit, and sand the wood. You can give much effort while sanding as it will help to smooth the layer of the stain. But if there’s a water-based stain, use 80-grit sandpaper instead. Avoid using any steel wool to sand the timber because harsh bristles can damage the upper part of the wood.
Steps Two- Prepare The Surfaces
Before start sanding, It’s vital to prepare the surfaces. Some users suggest using some water for sanding it well. But we must say sanding the wood surfaces depends on your efforts. Using water sometimes flattened the surfaces and made your task easy to eradicate the imperfections from it. Another benefit of using water during sanding has raised the moisture inside the wood. The fibers underneath the wood let you achieve the finish that you dreamed of.
Steps Three- Start To Sand The Wood
After choosing the right sandpaper for your wood, start to sand it. At first, try to do the task from the end of the edges, then gradually make way for the front. You can sand the wood using bare hands or gloves; it’s totally up to you. Do not sand the wood too roughly or too slowly. Make sure that you give your best while rub the sandpaper over the wood.
Steps Four- Embed The Second Layer Of Stain
This is the last step, but not least. Here you need to keep sanding until you get the final result. After finishing it, you’ll get a whitish powder around the wood. Wipe these using an old cloth or a thinner brush. Some wooden furniture has complexed drafts inside them. In that case, you can use a thinner toothbrush to remove the powder from it. After that, apply the second coat of stain once you’ve confirmed all the whitish powder is shifted. Let the stain dry off. It will be all set then.
Purposes Behind Sand Between Coats
It is vital to sand between coats to create a perfect bond. In short, if you want to create an antique look on a natural or semi finished hardwood surface, then you should research more. Specifically, hardwood being used would give you the best results, like every wood has different sizes and arrangements of pores. Again, they absorb stains differently.
Comparatively, you won’t get the same results when it comes to oil-based stains. You may know, oil-based stains take more time to dry. For this, you will get enough time to clear out all the excess stains hurriedly. With polyurethane stains, you can’t use any heavy-duty stains. It doesn’t allow you to sand without using 320/400 grit sandpaper. It’s just because other harsh sandpaper may destroy the entire look of the can.
The same things happen while you’re using any water-based stains. Although water-based stains don’t demand high sandpapers, you need to sand between the coats of stain all the time. But these stains sometimes make the wood grains visible. To avoid this, it’s better to sand between the coats. Experts have suggested that sanding with 80-grit sandpapers gives you more delicate surfaces than before. The looks become shinier while you’re applying the stain again.
Types Of Stains
There are 5 different kinds of stains, each of them have some unique benefits. Additionally, most of the stains have varied requirements. That’s why we feel it’s necessary to introduce them to you. Have a look at a glance.
Oil stains are popular. Before applying the stain, It’s essential to sand the wood. Oil finishes will meld together with the help of stains.

You need to take an extra profile before working with this stain.
Polyurethane stains come with a combination of two. Both water-based and oil-based are involved there. Most importantly, here, you don’t need to sand between the coats. It’s just because polyurethane stains get easily dry and allow you to wipe the extra stains spontaneously.

- Remember, scratching means sanding lightly. This means you need to use low fine load sandpaper.
- Scratching helps to remove raised grain, which often occurs in wood. Raised grain is quite disturbing, and it results in a transit area from flat to end grain.
- Apply 3-coats in between scratching. It helps to give you the perfect finish.
- Test the stains thoroughly.

What Should I Use To Sand Between Coats?
You should use finer grit sandpaper to remove the scratches from the wood.180-220 sandpaper is required to leave the coarser grit on unfinished wood. It helps to sand lightly between coats of paints.
Again, 320-400 grit sandpaper is good enough to sand metal, bronze, or other hard surfaces. So you should choose the one according to your needs.

As an example, you need to wait longer for an oil-based wood stain, while a watery stain takes less time it. In general, you should wait 15-30 minutes after application. For getting a better finish and smoothness, you should wait until the stains get properly dry.
Will A Second Coat Of Stains Makes Wood Darker?
The second coat of stains didn’t give you a darker finish all the time. It depends on the stains’ characteristics. Some stains will really give you a darker finish, while some will not. Hence, use a hardwood sealer found at any paint store if you really want to get a darker finish. This will give your wood a darker finish more evenly. Furthermore, you can use gel-stains with a clean rag.
What Should You Do If The Wood Stain Won’t Absorb?
Well, it depends on the wood species. Some wood simply doesn’t absorb stains as well as others. As an example, maple is very finicky in the matter of absorbing stains. Along with these, oak trees absorb it very well. At the same time, very figured grain, oily wood-like teak, the residue of an earlier finish like urethane oil.
For this, you can scrub it down with harsh scotch bite, denatured alcohol, and try to stain it with water. You can try to mix stains with alcohol, which may reduce the issues particularly.
