How to Glue Felt to Wood
Gluing felt to wood is a necessary part of a lot of home DIY crafts, especially those you might do with young children. Doing it properly will make the project or craft last quite a bit longer.
Get Your Supplies Ready
First, you need to make sure you have all the right supplies to glue your felt to your wood project. We’ve detailed more specifics on the type of felt and glue to use below.
- Glue
- Felt
- Roller
- Foam brushes or paint brush
- Scissors or razor knife
- Template pieces
This list of supplies is necessary to make sure your felt lays flat, fits well, and adheres as it should to your wood surface. It will help you understand how to glue felt to wood and make sure it has a strong hold that lasts.
Select the Right Felt
Part of the problem when gluing felt to unfinished wood is the type of felt that you use. Because felt stretches to some degree, you want to make sure that you select a high-quality felt.
Low-grade felt can tear and stretch beyond repair when cutting it or gluing it on your wood surface. A high-quality felt will be more durable and allow for some give in handling. You’ll be able to cut it easier and adhere it to your wood project without fear of damage occurring.
Clean the Felt
We’re not talking about a detailed clean here. But, you don’t want to try and glue felt that has dirt or anything else stuck to it. So, give it a quick once over and ensure it isn’t dirty.
One great way to get stains and dirt out of felt is by using a handheld steamer. Use the steamer lightly, holding it a ways back from the felt, and operating on the lowest power setting.
Choosing the Right Glue

You have a few options when it comes to selecting the type of glue to use. This is often dependent on the type of wood surface you are applying the felt to. Large pieces of wood work well with a spray glue as you will be able to get even coverage of the surface.
You will have to tape off the areas that the felt will not be applied to when spraying the glue to prevent it from getting tacky.
Elmer’s Glue is another good option when you are working with a small wood project that requires several pieces of felt for full coverage. The Elmer’s Glue sticks well and will allow you to get into those tiny crevices easier.
You’ll have a good adherence with this type of glue and not have to worry about peeling of the felt.
We do recommend wet cement as the best option for gluing felt to wood. It sticks well and is easy to work with. You can use wet cement on virtually any size wood project that you have as it provides good coverage when applied.
Cut Your Template
Before you begin the gluing process of your felt to your wood surface, you need to cut your felt to the appropriate size of the wood surface to be covered. Use a template to create the exact dimensions of your wood piece.
You can use cardboard for all the template pieces you need. This will help you create the perfect guide for a lot of wood projects, along with different DIY crafts you might be making for a signifigant other.
Once you have created the template, you need to cut your felt to the appropriate size. Use your template to guide you and cut the felt to the exact measurements needed. A high quality jigsaw will work just fine.

When completed, you should have a felt piece that fits exactly into the predetermined wood surface to be covered.
Apply the Glue
Before you begin applying the glue to the felt piece, make sure it fits the surface of the wood perfectly. It should cover the wood entirely and not have any overhanging felt. When you are certain that the felt fits well, you can begin to apply the glue.
Use your foam brush or a paint brush. We like the foam brushes because they are cheap and easy to work with. If you prefer a paint brush, you will need to clean all the glue off the brush when completed using paint thinner or another solvent.

Apply the glue to both the felt and the surface of the wood using your brush. A light layer will do and provide plenty of hold. Make sure to apply the glue to the edges. If you are using spray glue, you can easily spray the wood surface and felt to create a strong hold to the wood.
Place the Felt
Carefully place the felt on the wood surface that you just covered with glue. Make sure to line it up properly and pat it in place. It works well if you use a roller to smooth the felt out and stretch it a bit to cover the wood properly.
This will ensure good adherence to the wood and prevent any bubbles or wrinkles from forming.
Make sure to secure the felt thoroughly in any corners or around any obstacles securely. For smaller projects with your kids, you can use a scraper to get into those tight areas easier.

- 2 Step-by-step guide for felting a flat roof
If you’re looking to protect the flat roof of your shed or other outdoor structure from the natural elements, there’s no better way than by laying down felt on the roof.
While felting a flat roof is not a particularly complex project, it does require some patience and perseverance to make sure that the felt goes on smoothly and evenly. This is a good DIY weekend project, requiring only a few basic materials.
Materials for felting a flat roof
In order to lay felt on a flat roof, you will need to gather the following materials and tools:
- Ladder
- Utility knife
- Tape measure
- Trowel
- 30-pound roofing felt (also known as #30 roofing felt)
- Plywood planks
- Galvanized nails
- Roof felt adhesive (e.g. bitumen)
In terms of materials, please note that there are several different weights for the roofing felt. This guide will use the more durable #30 roofing felt, although you can use #15 felt.
Step-by-step guide for felting a flat roof
Follow the 10 steps below in order to felt a flat roof.
Step 1: Measure the roof
You can either measure the roof from the ground or by standing on a ladder and actually going up on the roof. You will then need to measure the length and width of the roof. Multiplying these two together will give you the square footage of the roof.
As part of this project you are using three different layers of felt, so be sure that you then multiply this square footage by three. This will tell you how much roofing felt you need to lay.
Step 2: Prepare the roof
You must remove any rotted pieces of wood on the roof and replace them with your plywood planks. Also, you will need to remove any old felt on the roof, as well as any nails or roof staples. This is done to ensure a flat surface for the roof felt.

Step 3: Lay down felt and secure to roof
Roll your felt out on the roof and cut it to fit with a utility knife. Roll the felt so that it overhangs the edge by 2 inches. Let it stand for about 30 minutes and then, using galvanized nails and your hammer, nail down the first layer.
In terms of spacing, leave about 6 inches between nails along both of the short sides and the side lying next to the edge of the roof. As you secure the roof felt to the roof, make sure that it lies even and straight.
One way to do this is by starting your nailing in the center and working out – this allows you to pull the felt snug as needed.
Step 4: Repeat until roof is covered
If your roof is larger than just a single layer of felt, you will repeat the process in Step 3 until the entire roof is covered. As you roll out each additional layer, make sure that there are at least 2 inches of overlap.
This means that you will be nailing both the original layer and the overlap layer along the edge of the felt that is parallel to the roof edge. When the final piece of felt is added, you will need to make sure that all 4 sides (not 3, as in the earlier rolls) are secured to the roof.
Step 5: Prepare the second layer
The key to weatherproofing your flat roof is adding a total of 3 layers; thus you will repeat the earlier steps. Before adding the second layer, though, spread a thin layer of adhesive on the first layer using your trowel. This will help the two layers adhere to each other.
Step 6: Add the second layer
You are now ready to place the second layer of felt. Cut it with your utility knife so that it lies correctly and fits the roof, AND so that it will overlap the first layer by 2 inches. This overlap is needed to ensure a tight, weatherproof seal.
You can either walk over the roof to remove any air bubbles between the two layers or use your trowel to ensure a smooth, exact fit.
Step 7: Prepare the third layer

You are now ready to lay another roll of felt on the roof. As before, you will need to place adhesive on top of the felt.
Step 8: Add the third layer
Now you are ready to roll out the third layer of felt. Cut it to size with your utility knife and place it over the second layer.
Be sure that there are 2 inches of overlap with the previous layer, and that some felt covers the edge of the roof. Now place the third layer on top. As before, you will need to make sure that there are no air bubbles between layers.
Either walk over the felt with your feet to ensure a tight, secure fit or pat it down with your trowel. At this point, you will now have three different layers of felt secured to the roof.
Step 9: Final roof treatments
Now, spread some adhesive on top for maximum weatherproofing effect. You can now cover the surface of felt with gravel for added strength and durability.
Step 10: Clean up
You’ve now completed the felt roof installation! All that’s left to do is a final cleanup of materials from the roof. Dispose of any waste – such as old felt or used nails – in an environmentally-friendly way.

Safety tips for flat roof felt installation
Any time you are working on a roof and using a ladder, you must practice good safety. This includes taking extra steps to ensure that you always have at least one hand free as you go up and down your ladder to the roof.
If you are thinking about refelting a roof or replacing a layer of felt, take care that you use the appropriate type of roof felt and adhesive.
Conclusions on felting a flat roof
Laying down felt on a flat roof is an easy and effective way to improve the strength and durability of an outdoor structure like a garage or shed. By placing three even layers of felt and taking great care that there is enough overlap and that any seams don’t create a straight line, you can ensure that your flat roof will be optimally weatherproofed.
