Typical Characteristics

Characteristics

• • No primer is required
• Paintable
• Economical
• After Curing forms a tough, elastic and flexible rubber like material.
• Bonds strongly to most of the building material.
• Durable, remains unaffected by UV rays, ozone and weathering conditions.
• Resist to water, salt water, 10% dil. acids expect nitric acids, alkalies, most of the common chemicals, vegetable, lubricants, oils and fuels.
• It performs well in a temperature range from 5ºC to 80ºC intermittent.
• Slip resistant, can be applied in a horizontal joints as well as vertical joints.
• Movement capability Provides satisfactory sealing of the joint subjected to expansion, contraction, vibration and cyclic movement within the following limits.
• Movement joints upto ±15% of the width.
• Excellent reparability property.
• Waterproofing compounds can overcoat it. Also will be available in Light colors.
• Non-toxic.
• Sealants will not cause staining to concrete masonry or stones.

Application

• Sealing of joints in traffic areas, such as roads and car parking areas.
• Sealing of expansion, contraction & construction joints in a building structure such as, Basement, Subways, Retaining walls, External walls, Roof Terrace.
• Sealing of dynamic Structural cracks.
• Glazing joints of window, door frames and curtain walls.

Typical Joint Filled with Techseal 1PPS

Directions for use

Surface Preparation

• Surface preparation is the most important step before application of sealant to get best results and to avoid failure.
• The joint surface must be dry, free from dust, coatings, bituminous mastics, concrete curing agents, mould release agents, oils, greases, and loose particles
• Clean the joint surface by wire brush and sanding with emery paper.
• Remove dust by compressed air or paint brush.
• Wipe out oil and grease by solvent soaked cloth (such as xylene, toluene, acetone).

Back up materials
Insert compressed polyethylene, polyurethane, thermocol foam, neoprene, polyethylene, butyl rods as a back up material to control depth of sealant in the joint & provide support for tooling of the sealant.

Bond breaker
Fix bond breaker tape such as self adhesive polyethylene tape on the back up material to avoid adhesion of sealant to the third surface.

Masking tape
Apply masking tape such as self-adhesive polyethylene, cellophane or cloth tape on both edges of the joint. It is used to improve the neatness of the finished seal by protecting the face edges of the joint. It may be removed immediately after tooling of the sealant.

Tooling & Finishing
Tool the sealant by pressing the puffy knife against the sealant surface, moving along the length of joint. Tooling is necessary to remove voids, ensure good wetting of interfaces and give neat aesthetic appearance.
After tooling, the masking tape should be removed immediately.


Coverage
To estimate the quantity of Techseal 1PPS required to seal the joint can be very easily estimated by using the following formula,

L =    625   
       W x D

L = length of joint in linear running meter
W = width in mm of joint.
D = depth in mm of joint.

Width to Depth ratio, width = 2 Depth

Cleaning of tools and equipment
Tools and equipment can be easily cleaned with solvents as Xylene, Toluene , Methyl, ethyl, ketone or Acetone.


Storage and shelf life
Store the material at cool and dry place ( at 20°C temp. & 50% RH)
Shelf life is six months in unopened conditions at a recommended storage conditions.


PACKING
Techseal 1PPS 4 Kg, 1Kg.and 600ml cartridge.

PRECAUTIONS
• Some people are sensitive to resins, hardeners, solvent and its vapours so it is advisable to use hand gloves and goggles.
• Avoid application below 10°C temperatures.
• Avoid application on damp or moist substrate

STORAGE: store at cool & dry place.
