6 Steps on How to Get Rid of Stain Lap Marks on Deck

1. Sand Down the Area

Refinishing a deck can be an arduous task, but the results are well worth the effort. To make sure you get the perfect finish every time, start by using a Palm Sander to sand down any areas with lap marks. 

This will help to remove much of the existing finish and smoothen out the surface, making it more receptive to refurbishing. For this step, use 80-Grit sandpaper for best results – it has just the right amount of abrasiveness that won’t scratch or dull your decking material. After a few minutes of work, your deck will be looking as good as new!

2.  Vacuum Up All Debris From the Sanding

Removing lap marks from a wooden deck can seem like a daunting task, but it’s a fairly simple process if you know the right steps. To start, vacuum up any debris or dust after sanding your deck. Be sure to pay close attention to all cracks and crevices so that no debris is left behind before taking the next step. 

After you are finished vacuuming, use a damp cloth to wipe away any additional dust or dirt that may still be present, taking care not to allow any water seepage between wooden planks if they are attached. 

Apply the appropriate stain, sealer, or lacquer evenly with a paintbrush or roller while avoiding lap marks altogether. With these steps, you can successfully restore your deck and make it look as good as new!

3. Apply a New Coat of Wood Stain

Preparing to apply a new coat of wood stain or sealer is an important step in getting the most out of your deck finish. Using either a paintbrush or applicator, start by wiping away any dust and dirt from the surface before applying. Then, using long even strokes with the applicator or brush, apply at least two coats of stain or sealer per manufacturer instructions. 

Be sure to let each layer dry completely before moving on so that you don’t end up with lap marks in your finish. After all of your hard work, you’ll be proud of the results and know you added value and have extended the life of your deck’s protective coating.

4. Allow the Stain to Dry Completely

Doing a thorough job when it comes to removing deck stain lap marks is essential to achieve a professional-looking finish. Allow the stain to dry completely before continuing with the next step. Doing so will help ensure that any remaining stains blend in more seamlessly and can give you an overall more attractive and longer-lasting result. 

Additionally, this helps you avoid having patchy spots or streaks on your newly refinished deck. Taking the time to let the stain dry completely may add a few hours or days to your total project timeline, but is well worth it for the result!

5. Sand Down the Area With Lap Marks

Make sure you use extremely fine-grit sandpaper for this step, such as 220-grit. If your deck has bedeviling lap marks left over from a stain job gone awry, never fear; these blemishes can quickly be erased with the help of thorough sanding. To get rid of the unsightly stains, begin sanding down the area in question using a palm sander.

Make sure to use extremely fine-grit sandpaper, such as 220-grit, for this step. Continue sanding until you’ve achieved an even surface once more that fits in with the rest of the deck. With a little bit of patience and elbow grease, those stubborn lap marks will soon be nothing more than a distant memory!

Use Extremely Fine-grit Sandpaper

6. Apply a New Coat of Wood Stain

This will help to protect your deck against future weathering and wear and tear so that it looks its best for years to come.

Applying a new coat of sealer or wood stain to your deck is the last step in protecting it from the elements and maintaining a polished look. After you’ve properly cleaned, scraped, and sanded your deck, make sure to apply the oil-based sealer or water-based wood stain evenly using wide strokes for an even finish. This will help ensure that you don’t get any lap marks on your newly refreshed deck surface. 

Do take care not to put too much pressure when applying the sealer or stain as this could cause it to collect too thickly in certain areas, leading again to uneven results. Allow plenty of drying time between coats for a beautiful finish and lasting protection from Mother Nature’s wear and tear.

Following these simple steps should help you achieve a smooth and even finish for your deck, leaving it looking better than ever. With regular maintenance, you can keep your outdoor space looking great all year long! Good luck and happy refinishing!

Tips on Getting Rid of Stain Lap Marks on Deck

Apply a Thick Layer of Deck Paint
  1. Use a putty knife or old credit card to scrape off any loose paint from the lap marks.
  2. Apply a thick layer of primer to the affected area, making sure to extend it beyond the edges of the lap marks.
  3. Once the primer is dry, apply a thick layer of deck paint to the affected area, again making sure to extend it beyond the edges of the lap marks.
  4. Use a roller with an extension handle to apply even pressure while painting.
  5. Start at one end of the lap marks and roll in a zig-zag pattern until you reach the other end.
  6. Allow the paint to dry for 24 hours before walking on it or applying a second coat of paint.
  7. To avoid lap marks in the future, always load your roller with enough paint to cover an area twice as large as you are planning to paint.

How to Refinish Your Deck and Avoid the Dreaded Lap Mark Syndrome?

The process of refinishing a wood deck can seem daunting, but there are some simple steps you can take to ensure your project is successful. One important tip to keep in mind is to work with the grain when applying the sealant or stain. If you move against the grain while coating, you risk creating “lap marks” that will be unsightly and difficult to fix. 

To avoid this issue, use a quality brush and start at one end of your deck, working back and forth with strokes that follow the direction of the grain. For an even finish, do not overlap each coat; put down an even amount of product each time until your entire deck is covered. Taking steps like these during deck refinishing will help ensure impressive results.

How to Achieve an Even Finish for Your Deck Without Any Blemishes?

Preparation is key when it comes to having an even, smooth finish on your deck without any blemishes. Before you begin any type of staining process, you must use a sander or power washer to get rid of the old stain or paint and make sure the surface of your deck is completely clean and smooth. Once all major obstacles have been removed, start sanding from coarse to fine sandpaper until you reach a level of smoothness that satisfies you. 

Use a Sander or Power Washer

Sanders can be rented from most hardware stores if needed. After sanding, use a vacuum or broom to pick up all dust particles left behind and make sure the area is free of debris before commencing the staining procedure. Applying multiple coats with long-lasting finishes ensures a high-quality shine that is free from any bumps or blemishes. This will leave your deck ready for some long days under the sun!


In short, to avoid or get rid of lap marks on your deck while staining- Without stirring the can too much. You should carefully determine how to get rid of stain lap marks on deck. Pour a small amount of stain into a paint pail. 

Apply the stain with a wide brush following the manufacturer’s direction. Move quickly but do not hurry as this will cause lap marks. If necessary, back-brush the stained areas to level out any pooling and ensure even coverage. Doing this technique should help you achieve an evenly stained deck without those pesky Lap Marks!
