STAUF's fitting range covers two ISO-certified structural adhesives, a PVAC glue for tongue-and-groove joints, and a DPM primer for absorbent subfloors — each suited to a specific stage of the job.
SMP 930: Hard Elastic Adhesive for Wide Boards
STAUF SMP 930 is a one-component, hard elastic SMP adhesive built to ISO 17178 for parquet flooring, suited to subfloor-friendly full-spread gluing of solid boards and multi-layer parquet. It reliably bonds boards with a width-to-thickness ratio of 7:1, a specification worth checking against your specific flooring if you're working with unusually wide boards.
Multilayer Hybrid: Elastic and Fast-Spreading
STAUF Multilayer Hybrid is also a one-component elastic adhesive built to ISO 17178, but formulated as a hybrid rather than a pure SMP product. Its excellent spreadability is designed to save time and effort during application, while its elastic mechanical properties and fast strength development suit multi-layer parquet installations where good ridging and quick handling matter.
Cold Glue L: PVAC for Tongue-and-Groove
STAUF Cold Glue L is a solvent-free PVAC adhesive specifically for tongue-and-groove bonding, curing to a transparent layer after brief pressing. It offers good water resistance for brief contact with moisture or high humidity, suited to universal joint-bonding applications rather than full-spread installation.
VPU 155 S: DPM Primer for Absorbent Subfloors
STAUF VPU 155 S is a fast-drying, solvent-free polyurethane primer for absorbent subfloors with a residual moisture content of up to 3.5 CM%. It's used to prep subfloors before filling work and direct bonding with reaction resin adhesives, and can also help bond highly absorbent or insufficiently firm subfloors — available in both 5kg and 11kg sizes depending on job scale.
Common Questions About STAUF Fitting Products
Should I choose SMP 930 or Multilayer Hybrid adhesive?
Both are one-component, ISO 17178-certified adhesives for parquet. SMP 930 is specifically confirmed for wide boards up to a 7:1 width-to-thickness ratio, while Multilayer Hybrid is built for fast spreading and quick strength development.
When would I use Cold Glue L instead of a full-spread adhesive?
Cold Glue L is for tongue-and-groove joint bonding specifically, not full-spread installation — it's a different job to SMP 930 or Multilayer Hybrid.
When do I need VPU 155 S primer before fitting?
It's used on absorbent subfloors, particularly where residual moisture content is a concern (up to 3.5 CM%), to prep the surface before filling or bonding with reaction resin adhesives.
What does the 3.5 CM% moisture figure mean for my subfloor?
It's the maximum residual moisture level the primer is rated for on absorbent subfloors — worth checking your subfloor's actual moisture reading against this before proceeding with VPU 155 S.
