How Do You Remove Old Paint From The Porch?


Before beginning any work on your porch it is a good idea to cover surrounding plants and surfaces with sheets. You can also add painter’s tape to the edge of your deck so that the stripper doesn’t damage the paintwork on your house.

If you have a concrete porch, you can remove old paint using a paint stripper. Paint stripper can be harmful to wood, metal, or stone, but is a good method for removing old paint from concrete. If you are working on a wooden deck, there are numerous methods you can utilize such as pressure cleaning, sanding, or chemical peeling.

All of these methods come with advantages and drawbacks, including safety risks. One of the most important things to remember is to wear a mask when working with old paint, to avoid any potential lead poisoning.

Other factors you may want to consider are cost, time, and efficiency. This is also a good opportunity to address any other issues such as nails that need to be hammered flush or panels that need to be replaced. Read on to find out what methods can be used to remove old paint; the benefits of each, and the hazards they pose. By applying this research to your deck you can achieve an effective outcome for your porch.

What Is The Easiest Way To Remove Old Paint From A Porch?

The three most common ways to remove paint from wood are stripping, sanding, or chemical peeling.

Stripping will involve using a deck stain remover. By using these products you have the added advantage of removing mold, algae, and dirt, along with your paint. By stripping the deck you are also cleaning it. But these products do come with the disadvantages of being expensive and hazardous. If the substance makes contact with your skin, it can cause a painful burn.

Sanding your deck involves using a power tool to remove the paint. By sanding you can even out the color of your deck, provide yourself a good base to apply a new color, and avoid using hazardous chemicals. Whilst sandblasting is a fast and efficient method that requires only a small amount of skill, it can leave a large amount of mess behind. Sanding by hand avoids this issue but completing the process by hand is time-consuming and physically tough.

However, sanding your deck adds the extra benefits of removing splinters and smoothing your wood, so it is a good option to consider.

Chemical peeling utilizes products such as solvent strippers or caustic strippers to lift paint and contaminants from the surface of the wood, but they are not designed to be used across large areas. If you have a small porch or a small area to clean, this could be a solution.

A further way to remove old paint from a porch is through heat. A blowtorch is a cheap and fast way to strip old paint, but it poses serious fire hazards, particularly as you are working with wood, and is therefore not recommended. If you do choose to use a blowtorch, make sure you have proper fire safety equipment, such as an extinguisher on hand and ready to use.

An alternative heat method is using a heat gun, which is safer than a blowtorch but still poses a fire hazard. 

Overall, heat sources are not recommended for paint removal but could be a considered option for small, hard-to-shift areas.

What If My Porch Is Concrete?

If your porch is made of concrete, stripping will likely be the most effective method to utilize:

To begin, scrape loose paint from the concrete with a scraper, before washing the area with soap and water. Allow to dry, then use a sander to remove any remaining residue or waxy substance.

Once clean and dry apply your paint stripper to the porch surface; the layer should be twice the thickness of your layer of paint. Check your product instructions for a guideline of how long to let your stripper set and leave to dry. Once the stripper begins to wrinkle, it should be ready to remove. The wrinkling suggests that the paint has been fully lifted.

When ready, remove the paint stripper with a scraper and wash your surface several times with water to remove any leftover stripper and residue.

It is best to do this on a clear day as the wind can cause the stripper to dry prematurely. If this does happen, apply a further coat before scraping away.

What Are Important Factors To Consider Before Choosing Which Removal Method To Use?

If you have an old deck that doesn’t look as though it has been coated before, a combination of high pressure water and chemical peeling is good to clean your deck of mold and mildew, whilst brightening the wood.

If you have a patchy deck, where some areas are painted and others are not, a stripper would be advised to lift existing paint. However, it is recommended that you try the stripper on a small area of paint to see if it achieves your desired effect. If not, the alternative solution is to sand off the painted patches and then use a chemical peel to lift dirt and contaminants for the wood.

If the existing coat of paint is cracking or peeling, you may find that stripping agents are not effective, and sanding could be your best option.

Whether pressure washing, sanding, stripping, or chemical peeling, it is a good idea to assess your options in terms of cost, time, and effectiveness.

Always refer to the products’ instructions and ensure you have the relevant safety gear in place before embarking on this job.
