ABAFLEX-LM

ONE PART POLYURETHANE JOINT SEALANT


DESCRIPTION
ABAFLEX-LM is a one part low modulus high performance polyurethane sealant, which
cures on absorption of atmospheric moisture to form a firm and flexible rubber watertight
seal for moderate movement and control joints. ABAFLEX-LM can be used in both horizontal and vertical applications.
 

ABAFLEX-LM

APPLICATION
ABAFLEX-LM is available in a ready to use self-contained sausage which can be loaded
onto a barrel gun. Start extruding the sealant into the joint firmly by maintaining an even pressure on the trigger of the gun. 
On vertical joints, sealant extrusion shall start from the bottom of the joint and continued to the top.
Once the sealant has been installed a suitable rounded tool can be used to achieve a smooth hour glass profile.
DO NOT USE SOAPY WATER SOLUTION. Any masking tape applied should be removed immediately after the sealant is installed.

JOINT PREPARATION
The joint edges must be clean, dry and free from oil, loose particles, cement laitance and other contaminants which may affect the adhesion.
 A thorough wire brushing, grinding, sand blasting or solvent cleaning may be required to expose a clean and sound substrate. 
When applied on glazed surfaces like ceramic or terrazzo tiles or porcelain enamel joint surfaces,
the glaze should be removed by abrading with sandpaper or wire brush.
 

ADVANTAGES

  • Highly resilient with excellent recovery characteristics.
  • Provides permanent and uniform watertight seal.
  • Excellent adhesion to most building substrates.
  • Can be used without the use of primer in new substrates.
  • Non-toxic. Can be used in potable water reservoirs and swimming pools.
  • Easy to apply, one component sealant. No mixing required.
  • Over painting can be done (Rigid paints may crack).
