Solvent-Based Deck Stain Stripper

These stain strippers work by chemically dissolving a stain or finish. Examples of solvents based strippers include:

  • Acetone
  • Toluene
  • Alcohol
  • Methylene Chloride

These are quite powerful cleaners that can easily remove old paint. The one major downside is that these strippers can be rather toxic. You will need to be careful when using, making sure you follow the product label instructions. Methylene Chloride has been made illegal in some countries; however, it is still available. So, to avoid this toxic chemical, it is best to check the label ingredients before purchasing.


Caustic Deck Stain Stripper

This stripper dissolves the old finish and changes it into another substance. These also require careful handling, as it involves potent acids or bases that are corrosive. Some examples of caustic strippers include:

  • Lye – sodium or potassium hydroxide
  • Oxalic Acid

Stain Stripper Buying Guide

So, now you know what types of deck stain strippers there are, and you want to go out and purchase something. However, there are a few things you need to take into consideration before you make a decision.


The Type of Finish You Need to Remove

Your first step is to find out what it is you want to strip from the deck. There are many finishes from varnish to solid stains, or do you wish to simply remove dirt. In some cases, you might require something more active or stronger to remove the finish. When it comes to a solid stain, it can be more stubborn to stip-off than a semi-transparent one. Understanding this can help you select the best deck stripper for the job.


Is It Eco-Friendly?

This might be something that is a top priority for you, as you might have several plants near your deck surface, and you do not want to harm any vegetation. Eco-friendly deck stain strippers are not only safer for the environment and plants, any pets and family members are safer too. When you are busy, some of the stains might also get into the ground, so a biodegradable product is extremely important.

Application Methods

In most cases, cleaning the surface is important and many suggest using a pressure washer for this purpose. However, you might not have a pressure washer and you might need to purchase or rent one. Search for instructions on the application which should be available through the manufacturer. Some deck stain removers might require certain application methods to be followed for them to work. Knowing what tools or equipment you might need beforehand can also help you be prepared.


Deck Cleaner vs Stain Stripper

Depending on the wood’s surface, you will either need a deck stripper or cleaner. Old, dirty, and wood with mildew are good candidates for a good deck cleaner. However, a stain stripper is more heavy-duty and able to remove paints, stains, varnish, as well as dirt and mildew. Again, it comes down to understating what your needs are and what the wood surface requires.

Paint and deck strippers are also different from each other. Paint usually forms a layer over the wood, while a stain penetrates the wood. Each product is formulated to deal with the differences. Your deck strippers soften and dissolve a stain that has gone into the wood better than a paint stripper.


Stain Stripper Quantity

Before going out to purchase your stain stripper, you should measure the deck size to get the correct amount of product. It is best to be prepared than having to return to the store again if you run out. Also, if you purchase a large quantity that will also be wasted as you will have excess product once done.


More Features

Try avoiding products with methylene chloride, as this substance is highly toxic. Thankfully, many manufacturers are now developing deck paint remover without it. Being biodegradable is another factor to consider when purchasing a stain stripper and you can always check for this. In many areas, this has become law.

How to Apply a Wood Deck Stripper

When following the instructions for the best paint remover for a wood deck, it is pretty much an easy process to follow. You may have to put some time and work into it, but the results will speak for themselves. AS with any type of chemical, it is best to stay safe and wear protective gear like goggles, gloves, and a mask if necessary. Wearing old clothes might also be a good idea, to prevent any stripper from messing up good clothing.

Always read the product directions before starting anything. There might be a few steps you need to take before you can apply the wood deck stripper, like cleaning the surface. Make sure to clear the area of any items that could get in the way. Covering or removing plants from the area is also a good idea, as many of the deck stain removers are caustic and can be toxic.

You may want to choose a small area to test out the deck stripper, so you can see how it works before applying it to the entire deck surface. Apply the stain stripper and allow it to penetrate for at least 30 to 60 minutes. If it appears nothing is happening, leave it a bit longer, as some stain strippers do take longer.

In most cases, no scrubbing is necessary. However, you do get some tough stains that might require a little scrubbing, or you can use a pressure washer to remove the finish. In some instances, sanding is needed and a wood brightener before applying a new finish.

Stain Stripper Application

There are various ways you can apply a stain stripper and depends on the product. You get stripping premixed products, and you can apply them immediately without problems. Others can come in a powder form that needs to be prepared, for example, mixing the powder thoroughly with hot water before applying.

Many find applying a stain stripper easier than using a sprayer. This application method provides an easy and even distribution of the stripping product and you can do large areas without difficulty. Make sure the sprayer you use can spray this type of material, as it could land up clogging the sprayer nozzle. You will also need to clean the sprayer after each use. Other methods to apply stain stripper include using a brush or a roller. Remember, always read the product label instructions before use.


Removing the Stain Stripper

The wood deck stripper can be removed by either scraping it off using something like a putty knife or by using a pressure sprayer. For larger areas like a deck, a pressure sprayer is by far the better option. You can either purchase a pressure sprayer or rent one for the job. Again, always read the product instructions carefully.


Additional Treatments

Applying an additional treatment like a brightener is a process seen by many as essential to refinishing your wood surface. Others believe it is not necessary to apply a brightener to the wood surface. It all depends on what you want out of the whole process. Caustic strippers can cause the wood to become dull and a brightener simply helps to restore the wood to as close to its original look.

We recommend you use a brightener if you are going to apply a semi-transparent stain onto the wooden deck surface. If you are going to be using paint or a more solid stain, then using a brightener is not as important. Since caustic strippers tend to make the wood surface look faded, if you want to revive it, then applying a brightener is a good idea. So, make sure to consider this when doing refinishing your wooden deck.
