Luan plywood, also known as Meranti, is a versatile and lightweight wood product used in various applications. It is commonly used in interior projects due to its smooth texture and can also be used in exterior projects due to its attractive color. However, Luan plywood can be stained due to its high content of resin and other chemicals, which can leach out and stain tile grout or vinyl.
To make Luan plywood, thin plies of wood are laid over each other at right angles until the desired thickness is reached and glued together. Luan underlayment, if labeled as such, is made without voids in the plys and exterior grade glue, which is water-resistant but not waterproof. Any Luan stamped exterior can be used as an exterior plywood, but it does not mean it can be used as boat building plywood.
Luan plywood is usually a cheap ply with indoor and outdoor grades. Exterior Luan plywood does not require a sealer and is glued with waterproof glue. The interior grade may be sealed with a latex adhesive. However, this adhesive product is flexible and does not create a reliable glue bond.
Finally, Luan is not rated for outdoor use due to its lack of water resistance and durability. To attach vinyl flooring to Luan plywood, the type of glue used depends on the project. Exterior plywood sheets for outdoor use are made with waterproof glue to stand up to the weather. Plywood comes in various types and types, making it essential to choose the appropriate type for your project.

What is Luan sheet lumber best used for?
Lauan plywood, also known as Luan Plywood, is a 1/8″ – 1/4″ tropical hardwood plywood panel used in flooring, lamination, paper overlay, furniture, and millwork applications. Originating over 40 years ago in Japan, Korea, and Taiwan, the first Lauan panels were manufactured using tropical hardwood logs from the Philippines, Indonesia, and Malaysia. The primary species used was Shorea spp., also known as “Lauan” in the Philippines. This species is now known as Philippine mahogany and Meranti plywood in the United States.
What plywood is made with waterproof glue?
Marine-grade plywood is a high-quality hardwood plywood manufactured with waterproof glue, offering water resistance, lightweight durability, strength, and minimal defects. If properly maintained, it can last for 15 to 25 years, which makes it a popular choice for exterior building projects, particularly in coastal areas. Furthermore, the durability of this material is enhanced by the application of a robust protective coating.
What is the difference between plywood and Lauan?
Meranti plywood, also known as Lauan, is a type of imported tropical hardwood plywood with several drawbacks. Its raw material comes from non-sustainable sources, leading to over-harvesting and destruction of tropical rain forests. The plywood is poorly packaged, causing damage during shipment. It comes in various sub-species, causing inconsistent appearance and density. Additionally, the panels may contain natural resins, making glue bonding and finishing difficult. RevolutionPly® plywood, made from sustainable wood sources, contains no tropical hardwoods and is produced from trees harvested in 7 to 10 year cycles.
How to waterproof exterior plywood?
To waterproof plywood, a variety of materials may be employed, including epoxy, waterproof paint, oil, varnish, latex, or PVA. These materials are suitable for both indoor and outdoor applications and are available in both paint-on and spray forms. They facilitate bonding and protect the wood from moisture.
Does CDX plywood have exterior glue?
The letter “X” in CDX plywood refers to the type of glue used in the factory to bond plywood veneers, not “exterior”. It stands for exposure, meaning the plywood is tough enough to withstand moisture for a short time. CDX plywood is suitable for laundry rooms, bathrooms, and places with occasional dampness or high humidity. It is water-resistant but not waterproof and can be ruined from a leaking tub or toilet. CDX plywood is often used under shingles, roofing felt, walls, and as a sub floor.
Although it is easy to find, it is not suitable for smaller projects like bookshelf or furniture. However, it can be used for creating rough shelving in basements or garages, where function is more important than appearance.
Is Luan wood waterproof?
Luan plywood is not suitable for flooring due to its lack of water resistance and tendency to swell and deteriorate when exposed to moisture. It is recommended to use sheet vinyl flooring instead of vinyl tiles over Luan underlayment. RevolutionPly® plywood offers a uniform color, easy cutting, sanding, and finishing, making it ideal for woodworking projects. However, Luan flooring lacks water resistance and can swell or degrade when exposed to moisture, making sheet vinyl flooring a better choice.
Is there an exterior wood glue?
EVO-STIK Wood Glue – Exterior is a versatile adhesive suitable for both interior and exterior use. It is capable of bonding a variety of wood types, including wood, hardboard, chipboard, blockboard, cardboard, paper, and textiles.
What is the glue in exterior plywood?
Melamine Urea Formaldehyde (MUF) adhesives are moisture-resistant and strong, making them ideal for outdoor plywood projects. They can withstand various weather conditions and are commonly used in exterior-grade plywood manufacturing. The best adhesives for outdoor plywood should be applied evenly across the surfaces to ensure a uniform bond and maximum coverage. Proper clamping is also essential to hold the plywood layers together during the curing process, ensuring a tight and secure bond.
Is Lauan wood hard or soft?
Lauan, a heavy hardwood, exhibits characteristics similar to those of genuine mahogany and can display a range of colors, from dark red to pale grayish brown.
What kind of wood is Luan?
Over 40 years ago, the first Lauan panels were produced in Japan, Korea, and Taiwan using tropical hardwood logs from the Philippines, Indonesia, and Malaysia. The primary species used was Shorea spp., also known as “Lauan” in the Philippines. The Asian plywood industries favored Lauan due to its clean, straight logs, stable wood fiber, easy peeling, and consistent density and color. This species is now known as Philippine mahogany and Meranti plywood in the United States.

Shiplap may seem like a new fad, but it has actually been around for ages. It serves a very real and practical purpose and in this …
@AZ Expert I own a 1997 Monaco Dynasty, and my delamination is on the p/s rear bed window and the top roof to wall seal (water breached due to previous owner cutting the filon and using screws to hold down vinyl cap). I was successful at safely opening the wall from the outside first, taking everything apart even taking out the side window and awning plus the whole entire vinyl screw cap seal(the vinyl screw cap seal was a mess so I felt the need to clean the entire seal while it was completely off). Now that I see the delamination has gone on for longer than 5 years most likely, the inside shelves, nightstand and cabinets had to be removed because so much water has breached the inside. in thus I am at where I am with everything apart ready for some sheet metal and new wood. Majority of the screws from the cabinets and shelves just broke because they were so rusty. I ended up forcing out most of the cabinets and it wasn’t easy. So my questions to you are, I have bought cheap construction 1/8 inch plywood from home depot which looks exactly like the luan in my coach. Its cheap and cost me nearly nothing and are returnable. Do you suggest coating these with Kilz primer before installing the inside wall of the coach or even outside wall? or should I return and get something else? Also, do you have any alternatives to the stabond duo? I have a hard time buying +$600 worth of something I’ll only end up using very little of. Unless this is absolutely required. I will only have about 4ftx 7x of Luan or plywood to reapply.
Hi AZ expert, thanks for the great articles. I have read through the comments here however I’m still not clear for Stabond 183 the 3m Equivilant is the Fastbond. However for stabond 440C the 3M equivilant would be Scotch Weld?or is this right? In Ireland here and it’s seeming very hard to get the Stabond 440, what would be the best adhesive for Luan to Luan be when 440C cannot be got?, most likely a 3M product as they are so universal. Any info again would be greatly appreciated!
Thank you very much for taking the time to make your articles. They are a tremendous help. I bought a 2002 Winnebago Journey DL 36 LD to give some TLC and fix up. Two important Items I’m dealing with is the basement Heat Pump and some sidewall delamination. Your articles on the Heat Pump repair is giving me a lot of help troubleshooting those repairs. The sidewall delamination problem appears to be about 50% of the sidewall about midway. Front quarter and rear quarter seem to be still attached. As you might imagine I can think of a lot of questions of how best to go about doing this myself. Some of these questions relate to resourcing the Luan, can I reuse/laminate the existing exterior fiberglass(?) sidewall skin or do I have to start over with new, etc. This may turn into too large of a job and I’m also considering the possibility of NOT trying to do this type of repair myself and just driving it across the country from Georgia for you to do the repair professionally. Is there a ballpark estimate available like you mentioned in comments of one of your roof replacement articles?
I’m sorry if this is the wrong place to ask, but I have a 2004 Itasca Meridian and there appears to be some kind of adhesive which attaches some hinges and panels to the body, for example on the front genset service access door, there are two hinges – one on each side – and the left one has let go. This same adhesive is used on the aft engine service access door, and all three of the glued contact points on top have let go. Is there a product and process you can recommend for reattaching these? Thanks for your time in advance.
Thanks for the quick response to the adhesive question I had on your article How to repair loose laminated RV .sidewalls. Thought I should ask my adhesive follow up questions here instead. Appears Stabond E 183 and T 440 might not that easy to get in Canada if at all (still checking) You mentioned a weldwood product might work. I see several weldwood products, could you tell me which wildwood product would be use in each case I.E. E 183 use X and T 440 use Y. Also to confirm the stabond products are not a 2 part adhesive? and they are Both a water base product? for easy clean up of the sprayer? Jeff
You have an excellent you tube website. Thanks for showing the correct way to do things. You have a great work ethic. I have a 2002 Coachman Pathfinder with delamination on one side. As part of this there is a bubble that has liquid in it. I’m assuming it’s water. Do you know the best way to let the water out from behind the side wall?
