Fixing anchors 70 mm LTX-70

Applications

•  Mechanical anchoring of EPS (expanded polystyrene) and XPS (extruded polystyrene) boards

•  Fixing mesh on surfaces with poor adhesion

Technical specifications

Data according to the Estecha 2026 catalogue. For any additional technical information, please get in touch through the contact form.

What materials is it combined with?

The anchor mechanically fixes the EPS/XPS boards that are then coated with the ESTonetex System mortars for polystyrene: ESTonetex Forte, a thin-layer decorative mortar that also works as a primer for TXT and Park, or ESTonetex Fibrax, a super-fibre primer mortar that avoids the need for fibreglass mesh. When mesh has to be fixed, these are the meshes in the range:

•  EST-Mesh 80 g/m² (REF 1300): roll 50 m long by 1 m wide (50 m²). Ideal for ESTonetex TXT and Park mortars and for coarse-aggregate mortars.

•  Tramaglass mesh 145 g/m² (REF 1303): roll 50 m by 1 m (50 m²). For mortars, renders and fine-aggregate mortars; ideal for ETICS (SATE) systems and applications on EPS and XPS.

•  160 g/m² ETICS (SATE) mesh (REF 1304): roll 50 m by 1 m (50 m²). For mortars, renders and fine-aggregate mortars; ideal for ETICS (SATE) systems and applications on EPS and XPS.

•  330 g/m² mesh (REF 1305): roll 25 m by 1 m (25 m²). Covering for iron-rod structures when creating artificial rocks and waterfalls; also reinforcement mesh for the lower areas of walls and façades.

•  Fibreglass veil 40 g/m² (REF 1309): roll 50 m by 1 m (50 m²). Reinforcement of surfaces coated with stucco, fillers or paints; ideal for repairing existing cracks in floors and walls.

How is it used?

It is a hammer-in mechanical fixing anchor: the polyamide nail is driven in with a hammer to anchor the board or the mesh to the substrate. The number of anchors, the anchoring depth and the type of substrate depend on the project and on the insulation system used. For reference, the ESTonetex Forte technical data sheet states that complementary mechanical fixings are required in addition to bonding: at least 6 anchors per m² and 8 fixings for heights above 25 m.

Observations and precautions

Professional product. Wear gloves and safety goggles when hammering. Before choosing this anchor, check that the insulation thickness and the substrate are compatible with the 70 mm nail; if in doubt, consult our technical team.

Complementary materials

•  ESTonetex Forte: thin-layer mortar for EPS/XPS used to coat the anchored boards

•  ESTonetex Fibrax: super-fibre primer mortar for EPS/XPS

•  160 g/m² ETICS (SATE) mesh: fibreglass mesh for ETICS (SATE) systems and applications on EPS and XPS

•  Other meshes in the range: weights and widths for each application

Frequently asked questions

What are LTX-70 fixing anchors used for?
To mechanically anchor EPS/XPS boards or to fix mesh on surfaces with poor adhesion. They are hammer-in mechanical fixing anchors with a 70 mm polyamide nail reinforced with glass fibre.

Is bonding the EPS/XPS boards enough, or do they need to be anchored?
It depends on the system. The ESTonetex Forte technical data sheet states that complementary mechanical fixings are required in addition to bonding: at least 6 anchors per m² and 8 fixings for heights above 25 m. The LTX-70 is a mechanical fixing for EPS/XPS boards; the project defines the exact number and positioning.

How many anchors are in a box and how many m² does it cover?
Each box contains 200 units. As a guide, with the minimum of 6 fixings per m² given in the Forte technical data sheet, one box covers about 33 m²; the actual quantity depends on the project.

How are the LTX-70 anchors installed?
They are hammer-in anchors: the polyamide nail is driven in with a hammer to anchor the board or the mesh to the substrate. The anchoring depth and the type of substrate depend on the project.

Can they be used to fix fibreglass mesh?
Yes, to fix mesh on surfaces with poor adhesion. The range includes 80, 145, 160 and 330 g/m² meshes and a 40 g/m² veil: the 80 g/m² mesh is ideal for TXT and Park mortars; the 145 and 160 g/m² ones for ETICS (SATE) systems and applications on EPS and XPS; and the 330 g/m² one for iron-rod structures in artificial rocks and waterfalls.

Which mortar is applied over the anchored boards?
On EPS/XPS, ESTonetex Forte is used, which also works as a primer for TXT, Park, Sulfo and Extreme, or ESTonetex Fibrax, a super-fibre primer mortar that avoids the need for fibreglass mesh.

What is the difference between the LTX-70 anchor and the staples in the range?
The LTX-70 anchor is a hammer-in mechanical fixing to anchor EPS/XPS boards or mesh on surfaces with poor adhesion. The galvanised ring staples are another fixing accessory: RT-C23 for pneumatic staplers (boxes of 10,000 units) and A20 for manual staplers (boxes of 1,000 units).
