About this item
- Up to three times the strength of conventional adhesive. That is Techniseal own figure, and it is a high strength, high solids polyurethane formulation.
- Permanent overnight bond. The wall you build today can be worked on tomorrow, which changes how a multi day build gets scheduled.
- It adheres to wet and frozen surfaces and resists water and frost once cured, so damp or cold conditions do not stop the job.
- Non shrinking, so it fills gaps and shims. That is unusual and genuinely useful. An adhesive that shrinks leaves a void behind exactly where you needed support.
- Long open time. Techniseal calls out flexibility in repositioning, which on heavy stone is the difference between a straight course and a fight.
- Smooth extrusion. Easier dispensing means less hand fatigue across a full day of wall building.

Why Structure Bond PU Paste?
Up To Three Times The Strength Of Conventional Adhesive, With A Permanent Overnight Bond
Two things slow a hardscape build: waiting for an adhesive to cure, and discovering the substrate is not flat enough to bond against. This product is aimed at both.

Description
Up To Three Times The Strength Of Conventional Adhesive, With A Permanent Overnight Bond
Structure Bond PU Paste is a high strength, high solids, low VOC polyurethane adhesive. Techniseal rates it at up to three times the strength of conventional adhesive, with a permanent bond overnight so the job moves on the next morning. It adheres to wet and frozen surfaces, resists water and frost, and the non shrinking formulation makes it usable for gap filling and shimming rather than just bonding flat faces.

Yield depends on bead size and on how much of the material is going into gap filling rather than a running bead. Gap filling consumes considerably more than a flat bonded joint, so estimate against your actual assembly.
Where Structure Bond PU Paste Works
Reach for PU Paste when strength, speed, or an imperfect substrate is the constraint.
- Retaining wall construction where next day progress matters
- Bonding onto uneven or irregular substrates that need gap filling
- Shimming and leveling stone and block
- Cold and damp weather construction
- Cap stones and coping on walls and pools
- Structural landscape features and columns
- Mixed substrate assemblies
- Repairs where the surface cannot be dried first
Where Structure Bond PU Paste Should NOT Be Used (Straight From the Manufacturer)
This is a paste adhesive, not the high yield canister foam. For long runs of bonding at volume, the Structure Bond canister system with the Gun II dispenser yields far more per unit.
For vertical veneer where sag resistance is the priority, StickyStone is formulated for that specific problem.
Bonding to wet and frozen surfaces does not remove the need to clear loose material, dirt, and ice buildup first.
