Matryx

Fields of Application

• Recommended for use on interior and exterior below grade
  concrete surfaces. Matryx gives protection against concrete
  decay and waterborne corrosive salts
• Can be used for negative waterproofing of concrete structures
  and on horizontal structural slabs against hydrostatic pressure
  as it provides strong resistance to impact and abrasion
• Basements
• Wet areas
• Tunnels
• Underground garages
• Planter boxes
• Structural concrete elements in high corrosion areas

Features

• Single component and easy to apply
  
• Can be used for positive or negative waterproofing
  of concrete structures
  
• Protection against rising dampness on ground slab
  
• Anti-corrosion coating

Application

Surface preparation

• The concrete surface must be clean and free from laitance, oils,
  grease, curing agents or other foreign matters. If surface is too
  smooth or highly contaminated with foreign particles, sand
  blast or acid etch surface before treatment.
  
• Concrete surface must be sound. Rout out visible cracks
  exceeding 0,4 mm wide, honeycombed pockets to depth of
  about 40 mm and width of 25 mm.
  
• Mix three parts of Matryx to one part water by weight, until
  stiff mortar consistency is achieved.
  
• Prime concrete surface with one slurry coat of Matryx before
  applying the mortar mix onto the area to be patched, tightly
  sealing the cavity.
  
• Matryx must be applied on damp substrate only to ensure
  maximum chemical penetration. Pre-wet substrate until damp
  prior to application of Matryx. If concrete surface dries out
  before application, it must be re-wet.

Application

• Apply a minimum of 2 coats in perpendicular directions, using
  a block brush or roller. The second coat must be applied while the first coat is still green but sufficiently set so that it is not drawn off while applying the second coat.
• The mixed material must not be applied at temperatures below
  5°C or on frozen surfaces. At no time should the total thickness
  exceed 5 mm in a single application.

Coverage

For Slurry coat / Brush application method, apply at the rate of
1 kg/m² depending on the area of application.
