Description  

Adheseal Allflex 101 is a flexible, clear-drying hybrid acrylic sealant for window and door perimeters, timber glazing, polycarbonate roofing and everyday building joints. It applies white so you can see the bead while tooling, then dries clear as the water evaporates. Once cured, it creates a paintable seal with ±25% joint movement.

Choose Allflex 101 when you need a discreet seal around compatible timber, glazing and exterior building materials without using a solvent-based sealant. Its water-based formula is easy to apply and clean up before curing, with good slump resistance for vertical joints.

Where Allflex 101 works

  • Timber glazing and joinery: bedding and weathersealing suitable timber glazing rebates and joinery details, not structural glazing.
  • Windows and doors: sealing compatible moving perimeter gaps around mechanically fixed frames.
  • Polycarbonate roofing: sealing appropriately designed roofing junctions after adhesion testing.
  • Weatherboards and exterior panels: sealing gaps and joints subject to modest movement.
  • Visible gaps and signs: neat, clear-drying sealing around compatible construction materials and display details.

What to know before applying

Allflex 101 cures through water evaporation, rather than the moisture-curing process used by many silicones and polyurethanes. Protect the fresh bead from rain and washing until it has cured and turned clear. Cure can take longer in non-porous or enclosed joint details, so allow an adequate route for drying. For movement joints, use the appropriate backing rod or bond breaker to prevent three-sided adhesion.

Allflex 101 is not for permanent immersion, heavily trafficked or high-abrasion joints, mirror bonding or structural glazing. Test sensitive stone, coatings and plastics. For higher-movement façade weathersealing, compare Hi-Flex Construction Plus.

Common Questions  

Does Allflex 101 dry clear?
Yes. It applies white and transitions to clear as it dries.

How much movement can it accommodate?
It is rated for ±25% joint movement.

Can Allflex 101 be painted?
Yes, after it has cured.

Can it be used in swimming pools?
No. Do not use it for permanent water immersion.

Uses & Benefits  
Hybrid acrylic sealant for interior and exterior moving joints, glazing and timber joinery bedding. Applies white and dries clear as water evaporates from the formulation. Accommodates ±25% joint movement and remains highly elastic after cure. Paintable after cure and suitable for many porous and non-porous building materials. Low VOC at 24g/L.
How To Apply  
Apply to clean, dry, sound surfaces. Concrete must cure for at least 28 days. For movement joints use a 2:1 width-to-depth ratio where possible. Internal joints require at least 6mm width and depth. External joints require at least 10mm width. For joints deeper than 10mm use open-cell foam backing rod about 25% larger than the joint width, or use bond-breaker tape to prevent three-sided adhesion. For non-porous surfaces in demanding applications, lightly abrade and use Adheseal 50A, then seal after 30 minutes and within 2 hours. For porous surfaces use Everflex Supaprime with the same 30-minute to 2-hour window. Tool within about 10 minutes.
Limitations and Safety Info  
Do not use for permanent water immersion, swimming pools or fish tanks. Do not use in high-abrasion or foot-traffic joints. Do not use in totally confined spaces. Do not use for structural glazing or mirror bonding. Do not use on lead or copper. Stain-test marble, granite and other stone before use. Composite panels require compatibility testing. Protect the sealant from water until it has dried completely clear. Do not expose curing sealant to solvents or cleaning agents that may affect or discolour it.
Suitable Substrates  
  • Glass, aluminium, anodised aluminium and powder-coated surfaces.
  • Timber and timber joinery.
  • Plastics, acrylic and polycarbonate.
  • Masonry, brick, stone and cement sheet.
  • Waterproof membranes, painted surfaces, rubber, fibreglass and porcelain.
