Roberts 3095 vs 6700: what are the tufting glue alternatives?
Both products are sold for carpet installation. Their data sheets do not test handmade tufted rugs, so the published carpet uses cannot tell you how either will behave on a tufted piece. Choose by the job and materials, then follow the exact label.

Roberts 3095 and 6700 have different listed uses
On narrow screens, scroll the table horizontally to read every column.
| Product | Manufacturer's listed use | What that says about tufting |
|---|---|---|
| Roberts 3095 | High-solids latex adhesive for interior direct or double-bond carpet installation. | The data sheet does not specify locking yarn into tufted primary cloth or attaching handmade rug backing. |
| Roberts 6700 | Adhesive for indoor/outdoor carpet. The data sheet limits outdoor use to covered exterior applications and excludes ponding water. | The installation specification does not establish a suitable tufting application. A listed "tufted" backing is a carpet construction, not a handmade-rug test. |
Read the current Roberts 3095 product data sheet and Roberts 6700 product data sheet. Confirm the regional label and current instructions before buying or applying either product.
Compare them with adhesive guidance for tufted rugs
A tufted rug can use one adhesive layer to secure yarn at the back of the primary cloth and another bond to attach a secondary backing. Those are different jobs. Tuft the World's finishing guide recommends a synthetic latex adhesive for its floor-rug tuft-locking step and discusses backing adhesive separately. This is the clearest documented alternative in the sources reviewed here, but it is maker guidance for its finishing system, not a head-to-head product comparison with Roberts.
See Tuft the World's adhesive and backing guide and its carpet backing adhesive information. The supplier discusses separate products for separate layers. Check the materials and application method its instructions specify.

Why owner reports disagree
Tufting owners report using Roberts products, but their results are not consistent enough to call one a universal choice. Discussions mention different glue jobs, rug construction, drying conditions, and desired flexibility. Those details matter, and the posts do not compare products under the same conditions.
Examples include owner discussions about looking for a different adhesive, Roberts 3095 and 6700, and choosing a tufting glue. These are individual reports, not controlled product tests.
What to check before choosing an adhesive
- Which layer are you bonding: tufted yarn to primary cloth, or secondary backing to the rug?
- Does the product label name both materials and your application method?
- What ventilation, cleanup, cure time, and temperature limits does the current label give?
- Can you test on an offcut made from the same cloth, yarn, and backing?
If the instructions do not cover your materials, ask the manufacturer before applying it to a finished piece. Do not infer rug performance from a carpet-installation data sheet.
Sources and limits
This comparison uses Roberts product data sheets, tufting-supplier guidance, and cited owner discussions. It does not claim hands-on testing or recommend Roberts 3095 or 6700 for tufting based on their carpet specifications alone.
