6 Best Mounting Putties For Lightweight Foam To Use
Looking for the best mounting putties for lightweight foam? Discover our top six expert-tested recommendations to secure your displays securely. Shop the list now.
Displaying lightweight foam boards, such as blocking mats or instructional signage in a craft room, requires a reliable adhesive that won’t damage delicate materials. Choosing the wrong mounting putty can lead to unsightly residue or, worse, the accidental tearing of foam surfaces during removal. This guide evaluates six industry-standard putties, focusing on how they interact with porous foam and delicate craft accessories. Understanding these nuances ensures that your studio space remains as organized as a well-managed stash of hand-dyed wool.
Loctite Fun-Tak: The Trusted All-Around Choice
Loctite Fun-Tak remains a staple in many sewing rooms for a reason: it offers a balance between tackiness and structural integrity. This putty works exceptionally well for securing lightweight foam charts or pattern references to vertical surfaces without slipping.
Its formula is particularly effective at holding light materials in place for extended periods without drying out prematurely. Unlike some adhesives that become brittle, this putty retains a certain malleability that mimics the drape of a well-blocked lace shawl.
When applying, ensure the surface is free of dust or lint, as fibers can compromise the bond. If the putty loses its initial grip, a quick knead will restore its elasticity and performance.
Scotch Mounting Putty: Best for Delicate Surfaces
Scotch Mounting Putty is often favored when the primary concern is the integrity of the wall or the foam itself. It provides a gentler bond, making it the ideal choice for renters or those working in studios with vintage, temperamental wall surfaces.
Because this putty is less aggressive, it excels at holding lighter materials that require frequent repositioning. It behaves similarly to a fine-gauge knitting needle—precise, delicate, and unlikely to cause damage if handled with care.
Avoid using this for heavy items, as the adhesive is designed for lightness rather than load-bearing capacity. It is the perfect tool for securing small foam reminders or color-work swatches that you intend to swap out regularly.
Gorilla Mounting Putty: For Maximum Sticking Power
Gorilla Mounting Putty is engineered for situations where a standard bond simply will not hold. If you are mounting slightly thicker foam core boards or heavy laminated instruction sheets, this product offers the superior shear strength required.
The trade-off for this intensity is a firmer texture, which requires more thorough kneading before application. Think of it like working with a high-twist cotton yarn; it is sturdy and reliable, but it demands a bit more effort to manage during the setup phase.
Because it adheres so strongly, it is best reserved for permanent or semi-permanent installations. Be mindful when pulling it away from foam, as the grip is significant enough that it could pull off the surface layer if yanked too quickly.
Dap BlueStik: A Reliable and Reusable Mainstay
Dap BlueStik is an iconic choice for crafters who appreciate a product that does exactly what is promised. Its distinctive blue color makes it easy to track during application, ensuring you do not leave stray bits of putty on your workstation.
It performs consistently across a variety of environments, unaffected by the slight fluctuations in humidity common in rooms where fiber arts are stored. This reliability makes it a go-to for hanging temporary foam charts during a large project.
When removed, it leaves very little trace behind, provided the application surface was clean. Always store it in a sealed container to keep it free from dust, which can act as a contaminant and reduce its long-term reusability.
UHU Tac: The Best Removable Putty for Crafters
UHU Tac is widely regarded for its clean removal, making it a favorite among those who frequently rearrange their craft room displays. It adheres well to foam and smooth walls alike without requiring excessive pressure to create a seal.
The texture is remarkably smooth, almost like a high-quality, pre-blocked mohair blend—refined and easy to manipulate. It does not pull or tug at the surface, which is a major advantage when mounting delicate foam projects.
Its greatest strength lies in its consistency, providing a predictable hold that avoids the frustration of sudden falling. It is highly recommended for crafters who prefer a “set it and forget it” experience for their lightweight display boards.
Faber-Castell Tack-It: Ideal for Lighter Items
Faber-Castell Tack-It is designed for precision and light-duty tasks, perfect for holding small snippets of foam or thin paper templates. It is subtle, unobtrusive, and handles the lightest of materials with graceful ease.
This putty is an excellent choice for organizing embroidery hoops or small knitting needle gauges against a foam pin-board. It provides just enough friction to hold the item in place without creating a bulky aesthetic profile.
While it lacks the heavy-duty grip of a construction-grade adhesive, its performance is ideal for the fine detail work typical of intricate needlecraft. It is the most discreet option for keeping your workspace organized and clutter-free.
How to Pick the Right Putty for Your Project
Choosing the right mounting putty requires assessing both the weight of the item and the texture of the surface. For porous surfaces like foam, a putty with a higher resin content, such as Gorilla, is usually necessary to penetrate the tiny air pockets for a firm grip.
If the goal is simple organization, such as pinning a gauge swatch or a pattern note to a foam board, consider the following checklist: * Weight: How many grams does the item actually weigh? * Surface Porosity: Is the foam dense or airy and fragile? * Permanence: Does the item need to stay up for months or just a few days? * Removal: Is the wall surface painted, wallpapered, or bare wood?
Selecting a product with the right balance of tack ensures the project stays put without the risk of tearing. Remember that excessive putty often results in a weaker bond, so stick to small, pea-sized amounts for optimal distribution.
Using Putty Without Damaging Foam or Walls
Proper removal technique is the secret to protecting both your foam boards and your studio walls. Never pull a piece of foam off the wall in a single, fast motion, as this can cause the adhesive to pull at the material’s surface.
Instead, use a rolling motion to peel the putty away from the wall gradually. If the putty feels stubborn, warming it slightly with a hair dryer can soften the adhesive bonds, much like steam-blocking relaxes a tight seam.
Always test a small, inconspicuous area first, especially on freshly painted surfaces. This simple precaution prevents a major headache and ensures your creative space remains in top condition.
Putty vs. Tape: Which Is Better for Foam Mats?
While double-sided tape provides a stronger, more permanent bond, it is often too aggressive for lightweight foam. Tape tends to bond so tightly that it can delaminate the foam surface, making the board unusable after a single application.
Putty is generally superior for foam because it remains pliable and does not rely on a permanent chemical adhesive bond. Tape is best reserved for mounting items to rigid surfaces like plastic or metal where structural integrity is not a concern.
When in doubt, choose putty for any situation involving foam-based displays or temporary pattern mounting. It offers a level of forgiveness that tape simply cannot match, protecting the longevity of your tools.
Can Mounting Putty Leave Stains or Residue?
Most mounting putties are oil-based, which can sometimes leave a faint greasy spot on porous surfaces if left for an extended period. This is especially true for foam or wallpaper, where the oil can migrate into the material.
To minimize the risk of residue, use the minimum amount of putty necessary to get the job done. If you notice a spot, do not attempt to scrub it, as this often grinds the adhesive deeper into the material.
Instead, take a fresh, clean piece of the same putty and dab it repeatedly onto the residue; the tacky surface of the fresh putty will often lift the old adhesive away. Consistent maintenance and periodic checking of your mounts will prevent these stains from becoming permanent.
Selecting the right mounting putty transforms the way you organize your workspace, allowing you to focus entirely on your craft rather than the mechanics of your display. By matching the strength and composition of the adhesive to your specific materials, you can maintain a functional and pristine creative environment for years to come.
