Crack & Expansion Joint Sealants

A Single Component ACRYLIC SEALANT For Roof Cracks

Properties: Single component ready to use, paintable acrylic sealant. It is suitable for cracks with movement of +/- 10% (expansion and contraction). Available in both plastic containers and in cartridges.

Application Method: Clean and widen the cracks to 5mm X 5mm wide section using a marble cutter and fill it with ALGISEAL ACRYLIC. After drying, fill the crack again. The ALGISEAL ACRYLIC must be filled at least twice. 2 to 3 applications are needed to get a level surface. For external cracks, the sealant should be covered with ALGICOAT RC 104 or Algiflexguard.

Coverage: 50 running feet per Kg.

Two Component Polysulphide Sealant For Expansion Joint & External Crack Filling

Properties: ALGISEAL PSD is a highly flexible, UV Light stable, chemical & solvent resistant Polysulphide sealant. It is a polysulphide sealant for filling of expansion joints with maximum of +/- 25% movement.

Application Method: Clean and allow the joint to dry. Apply ALGISEAL PS primer. Mix ALGISEAL PS resin & hardener to uniform consistency & apply into the joint.

Coverage: 20ft/kg for 12mm wide X 6mm deep joint. 9ft. / Kg. for 18mm wide X 9mm deep joints. 5ft. / kg. for 24mm wide X 12 mm deep joints.

Note: For horizontal and narrow joints width Algiseal PS pourable grade of polysulphide sealant can be used.

Butyl Tape For Exterior Cracks And Vertical Expansion Joints

Properties: ALGIBUTYL EXT is an exterior grade performed strip on a siliconised release paper. It comes with a fiber mesh sandwiched in butyl medium for additional tensile strength and is designed for exterior application. It has good adhesion to various surfaces and remains flexible throughout its service life.

Method of Usage: The product can be applied only on totally dried surface. In case the surface is contaminated use ALGIBUTYL solvent to clean the surface. If the surface is damaged or weak, it can be stabilized with ALGILATEX primer. Remove the release paper and apply the tape to the surface to be joined. Use roller to smoothen the tape after application.

Packing: It is available in 100mm width.

Fibre Mesh Of 4'' & 6'' For Crack Precaution In Building Joints

Properties: ALGIFIBRE MESH is a fabric made up of glass and coated with acrylic polymers that ensures good alkali resistance, high strength, good cohesion and excellent coating adhesion. It comes in ready to use 6 inch and 4 inch width and 50 meter length bundle.

Method of Usage: Apply thin coat of wet plaster on the surface(not more than 3 MM). Embed fibre glass mesh into the base coat or on brick wall directly in case of single plaster system. Apply a second coat of plaster until surface is smooth and fibre glass is at least 3 MM under the plaster. Stainless steel staples can be used to anchor fibre glass mesh to the first plaster. Use of ALGILATEX SP in plaster further improves the quality of the mortar/mesh system.

Economical Cementatious Crack Filler

Properties: Recommended for filling wide rigid cracks i.e., non moving cracks on internal walls. It is non shrink. Requires single application.

Application method: Clean and widen the crack, mix ALGICRACK FILLER and water in 3:1 proportion & fill up the crack using putty blade. Mix Algicrack Filler with Algicrete or Algilatex where improved performance & flexibility is required.
