The beauty of wood veneer is that it can be used in so many different ways. To get the most out of your wood, you should be aware of some fundamentals that will help you achieve the best possible finish for your project. Here we go over how to apply wood veneer in greater detail, among other things.
Step 1: Select two pieces of consecutively sliced veneer and check for grain pattern alignment before stacking them together. Apply painter's tape to the ends of the mated pair to keep them from shifting during the next steps.
Step 2: Trim the edge of one of the sheets with a utility knife and a straightedge. You'll want to keep the book-match pattern, so don't trim too much.
Step 3: Using a self-adhesive, join the edges together. Place the sheets on top of a scrap piece of MDF, with the cut edges about 1.5mm overhanging. With 180-grit sandpaper, sand the cut veneer edges square and straight.
Step 4: Carefully remove the painter's tape from the sheets and open them like a book. You can bring the joint in tight against the short lengths of painter's tape that are stretched across the seam by pushing the edges together (ensuring the good side of the veneer is facing upwards). Then, run another strip of tape down the entire length of the joint.
Step 5: Before applying the substrate to the veneer, draw the centerlines on opposite edges of the substrate panel. Check that the marked center is parallel to the taped joint line. Trim around the substrate with a utility knife, and repeat the process to create a veneer sheet for the opposing panel face.
Step 6 After layering the cauls with a platen and waxed paper, remove the clamps. Half of the cauls should be mounted on risers, with the crown facing up. Apply a thin coat of wood glue to one side of the substrate. Align the veneer with the substrate (the tape side should be facing away) and press down. Allow the glue to dry for 4-5 hours before removing the clamps.
Step 7: If the pattern shifted during the previous step and is no longer square to the edges, secure the panel to a sled with double-faced tape. Place this against the table saw's rip fence to true up one of the edges. Trim the panel to size with the same sawn edge against the rip fence or miter gauge. If the pattern did not shift and remained square, sand one edge of an MDF block with 80-grit sandpaper. This will remove any glue that oozed out after the panel was pressed, and the panel can then be cut to size.
There are two primary methods for cutting wood veneer:
The utility knife
After the veneer has been properly sized, you can score the back with a utility knife. Check that the blade is sharp enough before beginning, as a blunt blade can damage and mark the veneer. After a few passes along the mark, the blade should come through with a nice clean cut.
A small rotary saw can quickly make cuts in the veneer to avoid splitting or splintering. Before you begin, make sure you have a solid work surface and that you only begin cutting when the veneer is securely in place.
When gluing the wood veneer, extra care should be taken because this is a critical step in the process. If you're using a water-based adhesive, a foam rubber glue roller is the best way to apply it to the substrate; they're also inexpensive and can be reused. Take your time spreading the glue evenly across the surface and avoid using too much glue.
Before applying the glue, mark the substrate with a pencil to test the thickness. If you can still see the mark after applying the glue, you most likely used the correct amount. Rippling may occur if the veneer is overexposed to glue.
When it comes to deciding on the best glue for the job, wood glues are usually the best option. Alternatively, you can use 'cold press' veneer glue, which dries quickly, cures hard, and does not require any mixing.
Not all substrates have straight lines, and many have curved surfaces that may necessitate a slightly different approach to veneer application.
The most commonly used adhesives for curved surfaces are UF (urea formaldehyde), PVAs, or contact adhesives. To minimize movement during the process, you'll need to create a male/female jig and use a UF or PVA adhesive.
A contact adhesive is suitable for large pieces of furniture and is coated onto both materials, though they are better suited to back veneers rather than unbacked veneers due to their lack of movement resistance. Related product: Decorative Imitation Wood Grain Aluminum Veneer.
To create a smooth, finished look that blends in with the rest of the design, wood veneer edging is used to finish off shelving, bookcases, and cabinets. The following are the steps to apply wood veneer edging:
If you're working on something like a cabinet, it's a good idea to start with the longest edges first. Make sure the strip is a few centimeters longer than needed. Making the strip longer at this stage ensures that you have enough length and that you don't have to start over because the first one was too short. Trim the excess length by squaring the edge and ensuring the strip is flush with the side.
Set a regular household iron to a temperature just below the highest setting and run it over the strip, holding it in place with your thumb and forefinger. The ironing technique you use is critical; make sure to start with a 10-15cm section of the strip and keep the heating element moving. The strip should adhere to the plywood in about 30 seconds. After completing each section, press the strip against the edge with a wooden block or roller.
When you reach the end of the edge, flip the item over so that the strip is facing downwards toward the floor. You can now trim any excess strip pieces that are overhanging.
Sand the strip's edges with 150-grit sandpaper until it is flush with the rest of the item and no joins are visible.
If you want to change the appearance of your MDF speakers, follow these simple steps:
Any screw holes found on the speaker will need to be filled. This can be accomplished with wood filler and a putty knife. Make sure to do this on all sides of the speaker and scrape off as much of the filler as possible.
Smooth out the sides of the speaker with an orbital sander and a combination of 80, 120, and 200-grit sandpaper.
Create a diagram showing how the veneer will be cut from the sheet. While mapping out the bottom, front, and back sections, make sure the side, top, and opposing sides are all in one long strip.
Place the speaker on top of the veneer and use a utility knife to trace each side of the speaker cabinets. Make them a little larger so you have some wiggle room when it comes to aligning the veneer with the speaker. Label each piece so you know where it will go and how to keep the grain pattern consistent.
Apply the adhesive to the relevant section of the cabinet with contact cement and a 4-inch foam roller. Apply the adhesive to both the MDF and the veneer panel. Begin with the bottom section, then the back, the sides, the front, and finally the top. This order will help to conceal the veneer edges from the front and side sections.
Apply one coat of glue and wait for it to dry completely on both surfaces before applying the section of veneer you're working on.
After the second coat of paint has dried, place wooden shims or free paint sticks on the cabinet surface. This allows you to precisely align the veneer with the speaker's edges without it touching the MDF. Because you're using contact cement, once the two surfaces make contact, they can't be separated. When you are certain that the veneer is properly aligned, remove the shims and push the veneer down onto the speaker.
To ensure that the veneer is completely applied to the speaker, use a small wooden roller. Push down as hard as you can on every section of the veneer. Trim any overhanging pieces (for the side sections) with a utility knife, then smooth out the edges with 220-grit sandpaper.
You can then stain and finish the veneer to achieve the desired look, and the adhesive should cure in a few days.
Follow these steps to apply wood veneer to a kitchen cabinet:
Cabinet doors and drawers should be removed. Clean them to make it easier for the adhesive to adhere to them later in the process. Measure the dimensions of the cabinet doors and fronts and cut the appropriate-sized veneer with a utility knife, adding one inch in both directions to give yourself some breathing room. Label the sections so you know which goes where.
Sand down the cabinet doors to help the adhesive stick and remove any dust after you've finished.
To begin, select a door and place it on your work surface, along with the relevant piece of veneer. Using a paint roller, apply a thin coat of contact cement to the front of the door and the back of the veneer. Allow the cement to dry for 5-10 minutes, or until it is tacky rather than wet. Place the veneer on the door with extreme caution because once the two glued surfaces touch, they will fully bond and the veneer will be impossible to remove without breaking.
Before laying the veneer onto the cabinet, place several dowel rods over the cement on the door before laying the veneer on top. This will allow you to find the proper alignment without the two materials coming into contact, after which you can remove the dowels one at a time and adhere the door and veneer together.
Finally, use a utility knife to trim any excess edges and sand down the edges until they are flush with the other sides.
