Sikadur®-53 FLV

Moisture insensitive injection resin for sealing cracks > 5 mm

Sikadur®-53 FLV is a solvent-free, two part, moisture intensive injection resin, based on epoxy resin containing special fillers for sealing cracks in dry, damp, wet or underwater conditions.

  • Suitable for dry, damp, wet and underwater conditions
  • Cures without shrinkage
  • High resistance to a wide range of aggressive chemicals
  • Excellent adhesion to concrete, masonry, stone and steel substrates
  • Excellent adhesion to salt-water immersed, cement bound substrates
  • High density ensures complete water displacement
  • High mechanical strengths even after hardening under water
  • Injectable with single component pumps

Usage

  • Sikadur®-53 FLV is used as an injectable resin to seal damp and wet and submerged cracks by high pressure injection (the width of the cracks must be > 5 mm due to the special fillers)
  • For adhesion of concrete and steel in damp and wet condition (by water displacement)

Application

Application Information

Mixing Ratio

Part A : Part B = 4 : 1 (by weight)

Product Temperature

+10°C min / +40°C max.

Ambient Air Temperature

+5°C min. / +40°C max.

Substrate Temperature

+5°C min. / +40°C max.

Pot Life

~18 minutes (100g mass at +30°C)

(FIP 5.1)

The potlife begins when the resin and hardener are mixed. It is shorter at high temperatures and longer at low temperatures. The greater the quantity mixed, the shorter the potlife. To obtain longer workability at high temperatures, the mixed adhesive may be divided into portions. Another method is to chill parts A+B before mixing them (not below +5°C).
Application steps

SUBSTRATE QUALITY

Concrete / masonry / mortar / stone

Concrete and mortar must be at least 28 days old.

Verify the substrate strength to ensure design strengths are achieved.

Substrate surfaces can be dry, damp, wet or underwater, must be stable, clean, free from ice, dirt, oil, grease, coatings, laitance, efflorescence, old surface treatments, all loose particles and any other surface contaminants that could affect adhesion.

  

Steel

Surfaces must be clean, dry, free from oil, grease, coatings, rust, scale, all loose particles and any other surface contaminants that could affect adhesion.

 

Crack
Cracks must be clean and either dry, damp, wet or underwater.

SUBSTRATE PREPARATION

Concrete / masonry / mortar / stone
Substrates must be prepared mechanically using suitable abrasive blast cleaning, needle gunning, light scabbling, bush hammering, grinding or other suitable equipment to achieve an open textured gripping surface profile.
 

Steel
Surfaces must be prepared mechanically using suitable abrasive blast cleaning, grinding, rotating wire brush or other suitable equipment to achieve a bright metal finish with a surface profile to satisfy the necessary tensile adhesion strength requirement. Avoid dew point conditions before and during application.

 

Crack

Open all cracks into V grooves and seal them with appropriate rigid sealant from Sikadur® range according to site condition or type of sealing treatment required.

MIXING

Prior to mixing all parts, mix Part A (resin) briefly using a mixing spindle attached to a slow speed electric mixer (max. 400 rpm). Add Part B (hardener) to part A and mix Parts A+B continuously for at least 3 minutes until a uniformly coloured smooth consistency mix has been achieved. To ensure thorough mixing pour materials into a clean container and mix again for approximately 1 minute. Over mixing must be avoided to minimise air entrainment. Mix full units only. Mixing time for A+B = 4 minutes. Mix only the quantity which can be used within its pot life.

CLEANING OF TOOLS

Clean all tools and application equipment with Sika® Colma Cleaner immediately after use. Hardened / cured material can only be mechanically removed.
