How Do I Seal the Back of My Rug?
We like to call this process sealing, not “gluing,” because you’re not technically using glue — you’re using a latex-based adhesive that locks your fibers securely into the tufting cloth.
Choosing the Right Adhesive
For best results, use a liquid latex adhesive — ideally 100% pure liquid latex.
If you can’t find that, a latex-based compound will work too, as long as it stays flexible once cured.
Please note:
Rug backing latex is designed to wick into the fibers and stay soft and flexible.
Flooring adhesives (like carpet glue) are for sticking carpet to floors — they harden, crack, and can ruin your rug.
Adhesive availability varies by shop. Please check the relevant product listing or contact us before ordering adhesive for delivery to Canada.
Why Liquid Latex Is the Best Option
Liquid latex wicks beautifully up into the base of the yarn, locking it into the tufting cloth while remaining flexible.
You’ll know you’ve done it right if you can see a little latex rising into the base of the fibers — not so much that it seeps through, but enough that the yarn looks sealed from below.
If you don’t see this “wicking,” the fibers aren’t being held properly, and tufts may come out during carving or with use.
Here in Christchurch, New Zealand, where Carolyn, the founder of All Things EFFY, lives, there are several bespoke rug makers who use industrial tufting robots.
They all use the same liquid latex that we sell in New Zealand because it performs so well — strong hold, perfect wicking, and lasting flexibility.
How to Apply the Latex
There are several ways to apply your latex depending on your setup and the consistency of your glue:
1. Paintbrush
Ideal for runnier glues like liquid latex.
Works great for small rugs or detailed areas.
Just remember to clean your brush thoroughly — once latex dries on it, it’s finished.
2. Drywall Scraper or Spatula
Carolyn’s preferred method for smaller frames.
Lets you move latex around smoothly and evenly.
Works best when your frame is positioned horizontally on a table.
3. Paint Spray Gun
Perfect for larger rugs or vertical frames, especially with thin, runny glues like our liquid latex.
Apply light, even layers and let each coat dry before adding the next.
Prevents glue from pooling and wicking too far up the fibers (causing “glue dots” on the front).
4. Disposable Gloves (Manual Application)
Great for thicker glues.
Lets you physically work latex deep into the fibers with your hands.
A bit messy, but gives great control — just wear gloves and work fast.
Application Tips and Edge Sealing
Apply latex while your rug is still stretched on the frame. This gives better access to the fibers and ensures full penetration.
Apply latex beyond the edge of the tufted area — go about 2 inches (5 cm) past the last row of tufts.
This ensures you don’t miss the edge fibers, which are the most vulnerable to pulling and fraying over time.
Both types of EFFY latex (liquid and thick) remain tacky once semi-dry.
You can use this tackiness to your advantage when finishing edges — fold the edges of your rug over while the latex is still tacky and it will stick to itself perfectly, eliminating the need for extra glue or tape.
You don’t have to fold your edges if you prefer a clean cut right to the last tufted row — but folded edges add durability and protect the most fragile part of your rug.
Drying and Curing Times
EFFY Liquid Latex: Dries tacky in 15–20 minutes with a fan heater, fully cures in a few hours.
EFFY Thick Latex: Tacky after 24 hours, fully cured in up to two weeks depending on humidity.
If you’re in a hurry, you can remove the rug from the frame once tacky, but drying it while stretched ensures the fibers stay tight and uniform.
Important Notes for Grey Primary Tufting Cloth
Because grey primary tufting cloth has a single weft and warp, it’s more open than the white version.
If you use pure liquid latex, move it around quickly as you apply it. Letting it pool can cause glue dots to appear on the surface.
To avoid this:
Apply in thinner, fast-moving layers.
Use a spray gun for the most even finish.
This issue is rare but happens when the latex sits too long in one spot or is applied too thickly.
Why Flexibility Matters
The backing of your rug needs to stay flexible.
Latex-based adhesives flex with the rug, preventing cracking, flaking, and stiffness.
Non-flexible glues will harden and eventually crumble, especially if your rug is rolled or walked on frequently.
Even latex-backed rugs can dry out over time. After 3–5 years, it’s completely normal to reapply a light coat of latex to keep the backing fresh and supple.
We recommend using spray adhesive to attach your secondary backing — that way, it can be peeled off easily if you ever need to reapply latex in the future.
A Note on PVC Glue
PVC glue (common school glue) can work for wall hangings or decorative rugs that won’t be walked on or rolled up.
However, it’s not suitable for floor rugs — it can harden and even degrade fibers over time, making them weaker and more brittle.
In short:
Seal your rug using a flexible, latex-based adhesive and apply it evenly across the back — including beyond the edges of the tufted area.
Use the tackiness of the latex to fold and secure your edges, and always choose a glue that allows your rug to remain flexible and breathable.
Done right, your rug will be strong, smooth, and long-lasting — ready for years of use without cracking, shedding, or curling.
