3 Common Problems With Ipe Decking

Today we’re tackling a taboo decking topic – the biggest problems consumers have with Ipe wood. This decking material is costly, and you should know the facts before spending your hard earned dough.

You know the benefits of using heirloom grade wood, but can you spot the differences between normal wear and serious problems?

Proper preparation, proactive protection, and a working knowledge can take a project from disaster to delight. Stay tuned for valuable insights on guarding your investment from the start of installation through the life of your deck.

1. Improper Acclimation Problems

A frequent problem with all wood decking is improper acclimation. Even though you’re using Ipe outside, it still needs to acclimate to the conditions. If it doesn’t, you’ll increase the chances of splitting and separation over time.

The good news is, Ipe is hardier than cedar or redwood. It adjusts to temperatures and withstands the elements better than other species. Ipe can handle high humidity, dry climates and excessive moisture with ease, provided it’s given enough time to adjust on site.

Brazilian hardwood in its original state has a high moisture count. The level is brought down through a slow drying process to prevent cracking and splitting. The wood sits in a warehouse or lumber yard for months readjusting to its new environment.

Unfortunately, when the wood travels from the yard to a different climate, the acclimation process begins again. If the Ipe moves from a humid area to an arid one, it may dry too fast. Rapid moisture loss in any wood will cause surface cracks and separation.

The Solution

There are three things you can do to combat the chances of this happening to your decking material.

First, make sure the Ipe you buy is premium or select grade. This wood has the least amount of separation and cracks. Natural imperfections are limited to the boards surface and won’t affect their integrity.

Second, give the boards a few days to adjust to their new home before cutting them. The longer they sit on-site, the sturdier they’ll be when it’s time to start your project. Let the wood expand and contract naturally before stressing it with saws and drills.

Third, remember to seal the ends of the Ipe wood after cutting. When you expose the grain, the moisture level will change and spread throughout the wood. Applying sealer to the end of fresh cuts will slow the process and help prevent separation.

2. Excessive Movement

Adequate airflow is essential to maintaining your deck. Wood needs room to breathe, and air to help prevent moisture buildup. Without it, the dampness will sink in, and your Ipe will start to warp.

Yes, Ipe wood is dense, but it still moves with changes in humidity and temperature. If the moisture levels are higher under the deck than at the top, the wood will compensate for the difference when drying. This can cause coupling, gaps, and buckling.

To prevent this from happening, the airflow on all four sides must remain even. Make sure you space the joints evenly and allow room for expansion and drainage.

Even if you are building a lower deck, leave at least 18” for airflow under the joists. If the wood is too close to the ground or a concrete slab, their temperature can affect your Ipe. Consider oiling and sealing all 4 sides of the boards.

Another way to combat the problem is to create a slope underneath your deck for proper drainage and ventilation. Pitch the soil on an angle away from your home. Test it with a hose to ensure water isn’t pooling near your foundation or slab.

There are products designed for under deck drainage, such as membranes, waterproof flanges and under deck ceiling systems. You can find these products online.

3. Staining, Spots, and Sealing

If sap, pollen or leaves are left on the surface of your wood, they can cause dark stains. Regular cleaning of your Ipe will help lessen the effects. Make sure to sweep your deck and rinse the debris afterward.

Fading is typical in areas with high sun. You can use a UV protectant on your Ipe to cut down on damaging rays. If your budget allows, consider springing for an awning that extends over your deck.

Oiling your Ipe or sealing it will protect the finish. If you prefer to let your Ipe gray naturally, you can sand the spots, but be careful not to burnish the wood.

There are brightening chemicals on the market that you can use to lighten black marks or discolorations. Look for a product that is safe to use with Brazilian hardwood.

If all else fails, you may have to use a wood stripper and reseal your boards. Use caution with these products as they contain volatile chemicals. Always wear a respirator and gloves.

Final Thoughts

Ipe wood is one of the most durable decking materials you can buy. It’s gorgeous, low-maintenance and will stand the test of time. Ipe’s cost comes with a higher price tag than cedar or redwood, but requires less upkeep.

It ages and resists movement better than comparable wood species. This robust decking withstands the elements and adjusts to climate changes with ease.

It’s not without problems but has far fewer complaints than similar materials. Unlike PVC, ipe wood looks natural and will never scald your feet. Ipe decking is a one-time purchase that if correctly installed and maintained will last an average of 50 years.

    I have 2+ year old tigerwood decking. Looked great when installed. Waited 3 months before sealing. Now it is graying out some and I understand that. My concern is after protecting all furniture legs with felt pads and changing out when worn, my decking is marring/almost scratching every time we move furniture. I have contacted two contractors. One said to replace felt with something else!!??? The other has no idea what is happening. Any ideas for remedy?

      I did this (brown sheet) so that the lighter tiles on which the deck was laid did not show through. Be sure it does not allow pools of water to form though.

    I don’t want my Ipe deck too gray. It was installed last summer & I want to clean and stain it now. I will use a clean and brighten product, probably Restore a Deck. What oil do you recommend using? I have heard of Armstrong Clark (amber or mahogany), Messmers and Deckwise Ipe oil. Please advise.

    Helpful article! I read another article earlier that was comparing ipe wood to cedar and listing all the benefits of it. It is nice to also know what some of the drawbacks are!

    Is it normal for Ipe to have wood checking or cracks in the middle of the planks. I’ve noticed checking at the ends of the planks and I can cut that off. But I’ve also noticed that on my shorter runs when I cut the boards in the middle there are checking cracks in the middle also.

    Is that normal for Ipe?

    I’m building a dock on a reservoir and the local building inspector wants written documentation that Ipe is not toxic nor will become toxic to the water supply. Can anyone help address this concern?

    I’m interested in putting ipe over a concrete porch that is half covered and half not covered which extends into direct sunlight. I live in CA, the exposure is south west. The ground level that is covered by the roofline is concrete. The ground beyond the roofline is lawn. The deck will be attached to the house over the existing concrete porch and extended beyond the roofline, onto the lawn into direct sunlight by 9 ft. My preference is to let the wood age naturally, becoming silver grayish with wear.

    Wondering if this is the best product for my installation? Thank you.
