NOVERA SPIDER

NOVERA SPIDER

A highly flexible fiberglass reinforcing fabric
designed for maximum surface cohesion.

Strong as steel.
Light as a spider’s thread.

NOVERA Spider is like an architect’s fine mesh—knowing where a structure bends, where it works, and where it needs support.
It is not a surface and it is not a coating—it is reinforcement that connects the past with the future.

It is flexible when the building material moves.
It is strong when old masonry cracks.
It is stable when other layers need certainty.

Within the NOVERA system, it creates an invisible framework that holds everything in place—from elastic waterproofing to the final microspherical membrane.
It is the spider’s thread of the technical world—lightweight, precise, and incredibly strong.

BENEFITS

Highly elastic fiberglass fabric with long-term mechanical stability

Mesh structure for extreme tensile strength and resistance to deformation

Eliminates the formation and spread of cracks in structures

Strengthens damaged, cracked, or non-homogeneous surfaces

Resistant to alkaline environments, UV radiation, and temperature fluctuations

Suitable for both interior and exterior use, including wet zones

Ensures maximum substrate cohesion for thermo-reflective layers

Extends the lifespan of roofs and façades by decades

TECHNOLOGY

WHAT IS NOVERA SPIDER

NOVERA Spider is a specialized fiberglass fabric:

  • rolls: 50 m × 1 m
  • mesh structure for uniform stress distribution
  • high elasticity and tensile strength
  • high chemical stability in alkaline environments (concrete, mortars, cement)
  • compatible with NOVERA polymer membranes


NOVERA Spider is a specialized fiberglass fabric designed to:

  • dissipate stress in critical zones
  • prevent the transfer of cracks into final layers
  • stabilize structures exposed to thermal cycling from −35 °C to +85 °C
  • create a reinforced mechanical backbone beneath waterproofing and thermo-reflective layers

The fabric is a key component of the Cold Roof / Cool Roof system,
where it stabilizes old substrates prior to the application of NOVERA Reflex.

BASIC APPLICATIONS

On damaged or unstable surfaces

  • cracks
  • microcracks
  • uneven surfaces
  • different materials adjoining each other
  • weakened zones, leaks, old roofing layers

During renovation of older buildings

Where consolidation of old layers is required and the creation of a solid structural skeleton for surface membranes.

Within the NOVERA Reflex system (Cold Roof)

  • stabilization prior to the application of microspherical technology
  • ensuring perfect substrate cohesion

Under NOVERA HydroRepair

For heavily damaged or cracked surfaces prior to the application of elastic waterproofing.

On roofs, terraces, balconies, and concrete surfaces

Ideal for structures exposed to:

  • thermal shock (−35 °C to +85 °C)
  • vibrations (industrial halls, highways, ventilation systems)
  • water load (standing water, wind pressure)

APPLICATION

Surface preparation

  • surface must be dry, load-bearing, and clean
  • remove dust, grease, and biological film (recommended: NOVERA Cleaner)
  • recommended penetration with NOVERA PNT to improve adhesion
  • repair large cracks with NOVERA HydroRepair

Application

  • unroll and cut into required strips
  • place directly into the fresh HydroRepair layer
  • press in using a trowel / stainless steel tool
  • smooth to remove trapped air
  • overlaps between strips: 5–10 cm

Covering with subsequent layer

The fabric must be fully embedded:

  • it must not remain visible


Top layer according to the system:

  • NOVERA HydroRepair
  • NOVERA Reflex
  • NOVERA Exterior (for façades)

Temperature conditions

  • application temperature: +5 °C to +40 °C
  • do not apply if there is a risk of rain or condensation

Quality control

  • Check absorbency uniformity (e.g. using a simple paper absorbency test).
  • Perform an adhesion test using a pilot tape test on a selected area before full application.
