Can You Glue Pressure-Treated Wood? Yes

Many DIYers have trouble gluing pressure-treated wood. The problem is that some don’t know how to use a specific type of wood glue for gluing treated wood. Here in this article, we will introduce the types of glue and teach you how to glue pressure-treated wood.

Steps Of Gluing Pressure-Treated Wood


Thorough medication guarantees the success of your project. Considering that we’re dealing with pressure-treated wood, begin by wearing a dust mask and heavy-duty gloves.

It may feel egregious but, ensure you’re working in a well-voiced space, if not outside.

  • Clean The Wood

This step is pivotal for ensuring there’s no debris or pollutants moping on the surface. Cleaning both dry and damp treated wood also ensures the glue will cleave well to the treated subsurface.

Mix mild dish soap in a bucket of water. Dip a clean rag in the adulatory water and gently clean the wood surface. Repeat the process until the rag comes off clean when you run it on the surface.

  • Allow It Dry

How long does wood glue take to dry? Well, set the cleaned wood in a dry position and let it air sit for about 24 hours( or further).

Still, you can skip the drying time, if you plan to use polyurethane adhesives. This is because Polyurethane is a water-grounded adhesive. This means it adheres well to a damp surface and cures in the presence of humidity.

Still, if you’ll be using other types of glue, ensure the treated wood is dry before you do the coming stage of wood fix.

You could speed up the drying time by placing the wood under the sun if possible or using a dehumidifier if there’s no important sun in your region.

  • Plane Or Sand Any Unevenness

Once the treated lumber has sufficiently dried or if you choose to work with a plank of damp wood, run it through a plane to indeed out any bumpy knots and grain marks.

Alternately, you can consider grinding the surface using medium grit sandpaper and finishing with finer grit sandpaper. Only concentrate on the part you intend to glue.

Remember to only sand or plane smoothly to expose a fresh and smooth surface ready to take in the adhesive. Flashback, over-grinding or planning might strip the defensive chemical layer on the surface of the treated timber.

  • Clean The Dust Off

Since pressure-treated wood contains poisonous chemicals, collect the dust and dispose of them in a tip. Using a shop vacuum is a surer way to ensure that no grain of dust is left lying around.

Finish drawing by running a damp rag or method cloth on the field surface gluing needs a clean and smooth surface.

Apply The Glue 

Squeeze out the glue on one part of the set wood surface. Since there’s no correct way to apply glue, you can apply glue in indirect, zigzag, or long straight lines.

Spread The Glue And Attach The Two Pieces Of Treated Wood

There are two ways to do this: rub the two pieces of wood against each other or spread the glue using a comb or brayer.

Still, it makes sense to rub them together, if you’re clinging lower pieces of wood together. Still, if you’re clinging to larger pieces of treated timber, it’s presumably stylish to use a comb or anything you can extemporize with.

Whichever means workshop for you, ensure the glue covers every inch of the treated wood surface. Also, place and press the pieces of treated timber together.

Clamp The Glued Pieces

You need to hold the fused timber together while the glue cures this is meant to enhance cling. ensure that the fused pieces are aligned before setting.

You can use any suitable clamps available to you and suitable for the size of your glued pressure-treated timber.

Remove The Excess Glue Squeezed Out

Once you have securely clamped the fused pieces, there’s a chance you’ll notice redundant glue squeezed out. You can fluently wipe it out using a damp rag while the glue is still fresh.

Still, if the glue dries before you can wipe it off, use a plastic scraper to peel off the redundant dried glue.

Allow The Bond To Dry For Maximum Strength

At this stage, your work is done. the utmost glue should be suitable to dry solid in lower than 24 hours. Let the wood dry for that long or indeed longer if you’re not in a rush with your projects. Use these steps if you’re gluing pressure-treated plywood.

Problems With Gluing Pressure Treated Wood

glue pressure treated wood

When you have treated your wood to make it suitable for the outside, you may have to surface certain challenges if you try to glue the same wood later on. The subsurface of treated wood will generally contain substances from the chemicals and preservatives that might give you a problem when trying to glue the wood.

Still, you’ll surface further problems when trying to glue the pressure-treated timber boards to the same wood later, if you employ oil painting-type preservatives during the treatment process. Waterborne treatments are slightly less grueling in this regard. When you treat wood with high retention of pentachlorophenol or creosote, the heavy detergents render the wood unable to enter glue.

You can anticipate your wood with low pent retention to be more respectful towards glue, but wood with creosote treatment will be insolvable in this case. You must consider using waterborne treatments for your wood if you plan to glue it later because this particular treatment doesn’t dwindle the timber’s gluing eventuality.

Waterborne chemicals come responsive to glue once they’ve dried out fully. You can also beach or plane the subsurface first so that you encounter no problem at each in gluing the wood latterly. This step will only enhance the related eventuality of the lumber.

Best Glues For Pressure-Treated Wood

You’ll come across a wide variety of conventional timber adhesives in the request. Still, you must try to get the one that’s the most applicable considering the exposure condition. The only leak-proof glue line for your wood is resorcinol resin glues.

Polyvinyl and urea resin glues are the adhesives that will only give you a modest water-resistant bond. There are also certain types of elastomeric construction glues that give you competent humidity resistance and prove largely tolerant of high humidity contents in the forestland. The temperatures in these bonds are also lower than the conventional ones.

To help you narrow down your choices, however, here are the four introductory types of glue you need to always keep on hand for wood construction projects.

Polyurethane Glue 

Polyurethane Glue

Polyurethane glue is a marvelous water-resistant glue. It works so well against water that material does indeed better when it’s kindly damp with humidity. This glue’s characteristics make it a fine choice when you have to work on projects featuring pressure-treated wood.

Pressure-treated wood is frequently damp, and using polyurethane glue on stock dried in a kiln means that you’ll have to sprinkle some water on it to make it work.

It’s substantially a problem when you want to join end grain to end grain in terms of strength.

Titebond Iii

Titebond Iii

This adhesive is water-resistant and has good sand ability. It gives you roughly ten minutes of open time.

This specific tenacious quality is that it’s water-resistant only when it’s dry, but you can fluently clean its water when it’s wet.

Ellow Glue 

Ellow Glue

People of every generation are maybe familiar with yellow glue, the carpenter’s magazine. Yellow glue comes from the family of polyvinyl acetate and is an aliphatic resin. However, you can trust yellow glue to take care of the utmost of your gluing needs, if you plan to make cabinets or furniture pieces.

The benefits of this glue are that you can clean it with water while it’s still wet and it turns stronger than the wood you’re gluing together once it cures. Yellow glue also sands more. Still, it isn’t a good choice for damp materials.


This is another good candidate for the adhesives department. Cyanoacrylate bonds briskly, and you can find it in colorful density, from watery to jelly thick. You can use the thin variety for pouring into punky wood as reinforce glue.

Buying Guide: Best Glue for Pressure-treated Wood

You should try to follow the features before purchasing resorcinol resin glues for your pressure-textured wood. When looking for the best glue for pressure-treated wood, take a few things into account.

Typically, thick glues work best because they prevent mess. A firm and secure adhesion should be produced by the glue type.


The pressure-textured Bonds wood should work well with the glue due to its adaptability. Since most common wood glues tended to leak when being poured, they should be safe to use and simple to handle.


To help you reach awkward spaces without making a mess, glues should have a fine tip. You can control the amount of glue with the nozzle. You cannot, therefore, pour extra glue on wet wood. The nozzle is a big help. Look for glue that has a nozzle for ease of use.


You can use neutral glue after the glue has dried unless the glue is still visible after curing.

You wouldn’t believe that craft glue, especially the Elmer brand, which typically comes in a thick white color, would maintain its color after applying adhesive. However, the glue has properties that aid in drying, making crafting and other items less confusing.

Curing Time

The curing time of glue should always be tested. Additionally, there are numerous varieties of glue available on the market with a range of curing times. Depending on the glue, clamping times can range from 30 minutes to an entire day. In light of the curing time, you can make a decision.

Heat and Water Resistance

Any adhesive’s ability to withstand heat and water is one of its most crucial properties. Your wooden house will remain standing in any circumstance if the glue used is heat- and waterproof-resistant. Thus, the durability of the house’s structure cannot be compromised by heat or water.

What Else Can I Use to Join Pressure Treated Lumber?

There are a few other options besides glue that you might want to consider if you want to join pieces of pressure-treated lumber together. Whatever you want to achieve and how secure you want the connection to be will all depend on that.

Only stainless steel is frequently used by pressure-treated lumber manufacturers when treating their products. Nails, bolts, screws, connectors, anchors, and other galvanized options also work well in this situation. You might want to use copper or vinyl flashing to keep the new wood safe because it has been treated and is typically corrosive to aluminum.


Will Epoxy Stick to Pressure Treated Wood?

Pressure-treated wood is unable to accept epoxies, paints, or other film-forming coatings due to its high moisture content. In either case, the moisture may prevent the coating from curing properly or may eventually cause it to delaminate.

What Glue is Best for Pressure-treated Lumber?

The best construction adhesive for gluing pressure-treated lumber is a polyurethane glue. The humid environment of pressure-treated wood is perfect for curing this glue. Because it is waterproof, this glue is perfect for projects outside.

Which is Stronger Wood Glue Or Construction Adhesive?

Wood glue joints are impenetrable and never separate when properly applied and dried. Construction adhesive is more likely than wood glue to separate under stress. Use wood glue for any invisible cabinetry or woodworking joints.

How Do You Attach Pressure Treated Wood to Concrete?

The quickest and simplest method for attaching the majority of wood components to concrete is by using a powder-actuated tool. To load the barrel, use an ammunition nail and a. 22-caliber shell. As you press the nose of the shell against the workpiece, the fastener will be driven into the concrete when you pull the trigger.
