The Removal Process

Now that you have identified the appropriate product for your situation, it’s time to jump into the actual removal process. Here’s a step-by-step guide to help you navigate through it:

Step 1: Prepare the Area

Begin by clearing your deck of any furniture, plants, or other obstructions. This will create a clear workspace and prevent any potential damage to your belongings.

Step 2: Apply the Stripper

Follow the instructions provided with your chosen stripper product. Generously apply the stripper to a small section of your deck using a brush or roller. Make sure to work in manageable sections to maintain control over the process.

Step 3: Let It Soak

Allow the stripper to penetrate the failed coating according to the manufacturer’s recommendations. This typically ranges from 10 to 30 minutes but may vary depending on factors such as temperature and previous finish thickness.

Step 4: Agitate and Remove

Using a stiff scrub brush or scraper, agitate the softened coating to loosen it from the wood surface. Work in small circular motions until you see flakes of old finish coming off. Once loosened, scrape or brush away these remnants.

Step 5: Rinse and Neutralize

After successfully removing the failed coating, rinse your deck thoroughly with water to wash away any remaining residue. Next, neutralize the wood using a product like Net-Trol. This crucial step stops any residual effects from the stripper and prepares your deck for refinishing.
