By Editorial Team

Updated on November 20, 2024

In keeping with tradition and spanning eras, stunning without fail courtesy of its timeless appeal, a wooden staircase still needs, without a doubt, an eventual facelift to maintain its beauty. Before applying a new coat of paint or stain, stripping the wood is an essential step. How can you go about this sort of project, abiding by good practices, without damaging the wood? What are the most effective methods of stripping a wooden staircase? Keep reading to discover the best practices and techniques to revamp your staircase.

How to Revamp a Wooden Staircase in 4 Steps

To strip a staircase, you can either opt to use a heat gun or a chemical paint and varnish stripper. Since the former calls for the knowledge and skill set of a seasoned professional—a project which DIY novices should steer clear of—we’ll focus on the latter, meaning the chemical stripper.

1- Before stripping your stairs

Before moving ahead and stripping your staircase, gather the necessary tools and equipment to carry out the project. Within the scope of doing so, bear in mind that you’ll need rubber gloves, protective goggles, and a respiratory mask. Since strippers are chemical products, make sure the room in which you’re working is properly ventilated. Moreover, in case of spatter, protect nearby surfaces accordingly to avoid discolouring them.

2- What is the best way to remove paint from stairs? Use a chemical stripper

Now’s the time to apply a stripper. To do so, use a paintbrush. Start by applying the first coat liberally on the wood, and allow it to sit for several minutes, all according to the manufacturer’s instructions. Next, use a scraper to start scraping the paint off the staircase’s surface. If the stripper worked accordingly, you’ll see little bubbles all over the wood. Don’t be alarmed if you have to repeat the process several times to strip the wooden surface of its paint or varnish.

Tips and Tricks to Prevent Damaging the Wood

Come this step, you should carry out what is known as an “after wash.” Doing so consists of applying a neutralizer to eliminate all stripper residue that may be lingering inside the wood grain. To do so, we typically recommend using methanol. Simply apply a thin coat over the wood, and there you have it! Then, you can start sanding. Bear in mind that not overlooking this step is crucial, otherwise, the wood could get damaged in the process.

3- Sand your staircase

Once you’ve determined that the majority of the paint has been stripped, you can start sanding. The latter will allow you to remove small residue coating the surface while smoothing out and evening the wood.

Start by using coarser grit sandpaper, wrapping up the process with finer grit paper. The best way to achieve quality results is by sanding three times: once with 80-grit sandpaper, then with 100-grit sandpaper, ending with 120-grit sandpaper. Carefully proceed with all three recommended sanding steps to ensure the wood’s surface is devoid of marks, which is highly likely after the first sanding given how coarse the sandpaper is. 

How to Sand Faster

While manually sanding an entire staircase is feasible, we highly recommend using a power band sander. Otherwise, you risk spending an inordinate amount of time stripping your staircase.

While a band sander is quite effective in sanding steps and risers, it won’t be as useful when it comes to stair nosing. To sand the wood in said area, you won’t have a choice but to do so manually. Repeat the previously mentioned three sanding steps.

4) Clean the stairs

Before wrapping up, use a vacuum to remove the dust left from the sanding. Then, run a slightly damp sponge or cloth over the staircase’s surface. Doing so will ensure no residue is left behind, coating the stairs. This is a crucial step since the wood’s condition will dictate how your steps look once you’ve added a fresh coat of paint or stain.

How to Dispose of Paint Strippers and Scraps

Given the fire hazard, paint strippers should never be kept inside the home. Rather, sealing them in a container and storing them outside is advised, ensuring they're more than four metres away from the dwelling. Then, contact your local council authorities regarding when household hazardous waste is collected. That way, you can safely dispose of stripper scraps in an eco-friendly way.
