Contact cement is the fastest way to glue veneer to wood. The most effective substrates are MDF or multi-ply plywood. Also, remember to use glue with relatively equal moisture and temperature across the veneer and wood. Yellow glue may cause the veneer to crack or peel. Use a flexible and fast-drying solvent such as Contact cement for best results. Read this article for more information about veneer gluing. This article will also tell you what substrates to use and avoid.
Contact cement is the fastest way to glue veneer to wood
The quickest way to glue veneer to wood is with contact cement. A thick coat of the adhesive is required to adhere the veneer to the substrate. If you want to create an even finish, a second coat is usually recommended. A higher solids content contact cement is more expensive, but it will last longer and save you money. Ensure that the contact cement is 100% covered on the substrate and back. Porous substrates, like wood, often require a second coat of cement to adhere the veneer. The first coat acts as a sealer, while the second is a glue.
Contact cement can be applied to both bare wood and MDF, but raw veneer should not be used. It is almost certain that the veneer will pull apart, so PVA is a better choice. PVA will work with some veneers, but it is not recommended for all types. Some types of veneers may react with the contact cement, so you must be very careful while applying the glue. If you have a bare wood substrate, you can use a 3/4-inch plywood piece for cold pressing. It is also advisable to use wax paper between the veneer and the caul.
Before applying contact cement, make sure the surface is clean and dry. If you are gluing veneer over MDF, make sure that both surfaces are clean, smooth, and debris-free. Apply the adhesive according to manufacturer’s instructions. The adhesive must be tacky before application. After the veneer adhesive has dried, place separator strips 1″ to 2′ apart. You may need assistance positioning the veneer, but it is easy to do if you hire someone else to do this task.
MDF or multi-ply plywood are the best substrates
When gluing veneer to wood, MDF or multi-ply plywood are ideal substrates. These are both non-changing, so glue bonding can be done directly to the wood surface. Particle board with melamine surface is not suitable, so sanding is necessary before glue bonding. Otherwise, you can use cheaper woods. MDF or multi-ply plywood is the most reliable substrate for glueing veneer to wood.
If you’re planning to use MDF or multi-ply plywood as a veneer substrate, you’ll have a number of options. While MDF is cheaper than particle board and is often used to make furniture, MDF requires more work than particle board does. MDF is also more stable, meaning you’ll be able to get a flatter veneer. You can prepare MDF for veneering in the same way as particleboard – simply add a drop of water before gluing.
If MDF or multi-ply plywood are unavailable, particle board is a decent alternative. Although particle board is not as fine as MDF, it’s still a decent substrate and can be lightly sanded to give it a better grip. Using a water drop test to determine the quality of the substrate is also a great way to test its sanding. If the water drop sticks to the surface, then it’s time to sand it further.
It’s important to keep in mind that the glue may not set properly until a few minutes. If you apply glue too quickly, it may not set properly, and it will squeeze out of the veneer in several spots. While this won’t matter if you’re gluing veneer to wood, it’s best to use MDF or multi-ply plywood, as these are dead flat and easy to work with.
Ensure veneer is relatively equal in relative moisture and temperature
For the best results, it is essential to ensure that the wood and veneer are of roughly the same relative humidity and temperature before gluing. Ensure that the veneer is acclimatized to its surroundings by laying it flat on a work surface for at least 48 hours or 4 days. To help it maintain its flatness, apply a layer of adhesive to both surfaces, following the manufacturer’s instructions. Place separator strips between the veneer sheets, approximately one to two inches apart. If necessary, get some help to position the veneer sheets and remove the old ones after the veneer is applied.
Before applying finish, sand the newly applied veneer. The contact cement should dry thoroughly after 48 hours. After installation, lightly stain the veneer, but only apply it sparingly. Typically, oil or solvent-based finishes are recommended. Shellacs and lacquers are acceptable if used properly, but water-based finishes should be tested on a test piece before being applied to the veneer. Excessive application of finishing materials can cause delamination or bubbles.
Ensure that the veneer is fairly equal in temperature and relative humidity before gluing to wood. The first step in veneer gluing is to make sure the veneer is relatively equal in relative moisture and temperature. This will ensure that the veneer adheres to the wood properly. If you do not want to use any glues, you should consider applying a thin layer of abrasive paper. This will prevent any moisture from leaking through the veneer.
Avoid yellow glue
Woodworkers often turn to woodworking as a hobby or stress-reliever. But the time pressures of assembly projects can lead to stress. If you’re glued to your project, take a moment to relax. Drink some herbal tea and take a deep breath. Read helpful tips to help you make the most out of your woodworking project. Ultimately, the end result will be more beautiful and durable.
First, you’ll need to use a woodworking adhesive. Yellow woodworking glue will cause strikethrough, or glue that shows through the veneer. Yellow glue is a common choice. Cold-press veneer glue, produced by Titebond, is a better choice because it doesn’t show strikethrough as much. Use a generous coat of the adhesive on the wood surface before applying the veneer, which will bind the veneer to the surface.
The use of thicker veneers requires stronger glue. Standard thickness veneers lack strength-in-number, which is necessary for cold press veneer glue to hold firmly. Standard yellow glue isn’t strong enough to overcome this problem. And it doesn’t dry completely rigid. In short, ordinary woodworking glue will allow veneer to creep. Whether you’re gluing veneer to wood or building a decorative piece, use the correct adhesive.
Lastly, avoid over-applying glue. Yellow glue will interfere with the finish on your veneer, so don’t apply it over an area where you’ve applied paint. If you’re worried about gluing the veneer down, you can cut an area off with a razor knife. Alternatively, you can use a paint brush to apply a thin coat of glue to the surface.
Cross banding is a must in veneering
If you’re working with a long-grain veneer, cross banding will help you prevent internal checking and lift. In traditional veneering methods, long-grain veneer has a tendency to lift and splinter at its edges. But resin glues seal the edges effectively and do not require cross banding. Even today, cross bandings are popular in veneering reproduction furniture and as a surface decoration.
The main reason veneer glues don’t bond properly is because they fail to penetrate the surface. The surface must be porous for the glue to penetrate and stick. That’s why cross banding is so important. If you don’t use it, you’ll risk damaging the veneer by allowing glue to squeeze out of the joint. If you’re unsure of what kind of cross banding is needed, consult a veneering guide.
The cross banding is laid after the veneer is fitted to the surface. It can be glued into place or taped in place. A cellulose tape, which is ideal for using with resin glues, has an elasticity that allows the tape to stretch sufficiently to apply even pressure to the veneer. Sometimes, presswork involves dry fitting the entire surface and pressing central veneer and inlay banding. Sometimes, you may even need two presses.
The proper thickness of the veneer should be determined by the thickness and quality of the substrate. For thick veneers, the glue used for the veneer is too weak to stick to the surface. In this case, you should use a stronger glue like pre-catalyzed powder resin. In most cases, veneers should be a standard thickness. If you’re going to use veneering glue, you can use the same glue, but thinner veneers are best suited for smaller projects.
