Product details

KINTOP JSP

Self-adhesive Polymer Modified Bitumen Waterproof Membrane

Description 

KINTOP JSP (PET) Waterproof membrane utilized aluminized Mylar film or high polymer sheet(HDPE) as surface reinforcing material, covered with asphalt adhesive material which contains active agent rubber. KINTOP JSP can be used directly with polymer cement mortar in the construction (wet applied method), but also can be used according to the traditional construction method (dry applied), so as to meet the different needs of projects. This product is especially suitable for the continuous construction of waterproof engineering design, when the construction period is long, and the exposure time of the membrane also is long, the component of KINTOP JSP can function to reduce fold and the drum phenomenon of the materials.

 

Advantages

Main Application
• Roofing, underground waterproof engineering
• Concealed waterproof project with protective covering

Product Features
• Strong bonding property

• Outstanding bonding ability, good effect to bond with substrate, no water-channeling
• Strong anti-puncture and self-healing performance
• Great stability, good anti-corrosion performance, simple-construction
• Convenient and simple construction
Installation
Wet apply Substrate Preparation
The substrate should be strong, tight, smooth, clean and flat without flaws like bulge, looseness, sands, pitted face and rebar; The joints like internal & external corner, pipe root etc. should be plastered to be arc by cement mortar; The substrate needs to be moisture but without water flow. Spray some water if the substrate is too dry.
Application
• Wet the substrate if the it is too dry;
• Prepare the cement slurry; 
• Before widespread paving, make reinforce sheet on the internal & external corners, pipe root and outfall etc;
• Roll the membrane forward while coating the cement mortar;
• Pave the first membrane: cut the release film lightly by paper-knife. Lift up the film and make it be at an angle of 30 degree with the membrane;
• For the second membrane: pre-apply the membrane and overlap it with the previous membrane's lapping guide line. Make sure the lap seam is not less than 80mm;
• Overlap the long end of the membrane: Press the border by the rollers to vent the air from the lap seam;
• Overlap the short end of the membrane: the width of the lap seam is 80mm. 

 

Dry apply Substrate Preparation
The substrate should be strong, smooth, clean without bulge, looseness, sand, pitted face and rebar; The substrate should be dry and the moisture content is less than 9%.
Application
• Pour the substrate treating agent onto the substrate, coat the treating agent evenly by brush or roller without any omission and accumulation;
• Set the datum line according to the shape of the operating site and specification of the membrane. Unfold the membrane and make the adhesive side facing the substrate. Stretch the membrane from both ends to make it flat. Adjust the position according to the datum line then fold the membrane from both ends to the center and prepare to pave;
• The following procedure is the same as the wet-applied application.
• Pave the first membrane: cut the release film lightly by paper-knife. Lift up the film and make it be at an angle of 30 degree with the membrane;
• For the second membrane: pre-apply the membrane and overlap it with the previous membrane's lapping guide line. Make sure the lap seam is not less than 80mm;
• Overlap the long end of the membrane: Press the border by the rollers to vent the air from the lap seam;
• Overlap the short end of the membrane: the width of the lap seam is 80mm.
