Description

i.flow COULYS L & M are two injection grouts, natural hydraulic lime-based for the restoration of old masonries. Thanks to their soft compressive strengths, they are dedicated to stones they can not damaged.
 

Fields of application

Injection grouts (filling cracks, open joints and cavities in walls)

Properties

  • The two versions of i.flow COULYS allow a progressive hardening of the grout inside the walls
  • Setting starts 15 hours after application for i.flow COULYS M and after 22 hours for i.flow COULYS L
  • Strengths are lower to preserve the stones.
    At 28 days: i.flow COULYS L : 3.3 Mpa / i.flow COULYS M: 5.2 Mpa
  • The two versions allow work on different problems, such as those in old stone or brick buildings and they let the wall breathe
  • Good viscosity
  • No sweating or segregation
  • Guarantee of an industrial blend for better regularity

Advice

  • Always work between 8° and 30°C and outside of frost periods
  • Protect from the sun and the wind to avoid any setting problems
  • Store bags in dry conditions for a maximum of one year after the production date, as specified on the bags
  • Do not carry out any other grouting work using i.flow COULYS
  • Do not apply on substrates containing gypsum
  • Do not apply during periods of frost
