Mapei - Waterproofing Fibre Glass Mesh

Where to use

Reinforcing for: 

• Mapelastic used in waterproofing of terraces,
  balconies, swimming pools, bathtubs, shower stalls,
  etc., prior to installing ceramic tile or natural stone.
• Protective elastic finishing with Mapelastic applied
  over cement-based surfaces with crazing in interiors
  and exteriors.
• Waterproofing with Mapegum WP and Aquaflex in
  particularly stressed areas, e.g. joints between walls
  and floors, etc.
• Mapegum WP and Aquaflex when used as anti-fracture membranes over screeds or walls with
  crazing in interiors.
• Plastisol 1 when used for repair of cracked
  bituminous membranes and with Plastimul when
  applied over substrates with crazing.
• Polystyrene, polystyrene foam, rock-wool, and cork
  insulation installed with Mapetherm AR1 or mortars
  manufactured with Adesilex FIS13.

Application

The Fibreglass mesh must be completely covered by
the waterproofing or levelling compound:

• Apply an even coat of approx. 1 to 1.5 mm of the
  waterproofing or levelling compound with a smooth-edged trowel.
• Place the mesh over the waterproofer or leveller while
  still wet and gently press it in with the trowel so it is
  completely covered.
• When the surface has hardened (usually 12 to
  24 hours depending on the type of product used, the
  ambient temperature and humidity, and the thickness),
  apply a second coat of the product if needed.

The edges of adjacent sheets of fibreglass mesh should
overlap by at least 5 cm.
