Sealant XT100 – Modified Polymer Waterproofing Sealant
Sealant XT100™ is a modified polymer sealing material developed for suitable cracks, joints, gaps, penetrations, fasteners and other leakage-prone details. It is used as part of selected KCS repair and waterproofing systems before or alongside membrane treatment.
What Is Sealant XT100?
Sealant XT100™ is a modified polymer sealing material used for suitable cracks, joints, gaps, penetrations and leakage-prone details on compatible surfaces.
Its primary role is detail sealing. XT100 is not intended to replace a complete waterproofing membrane where a full-surface waterproofing system is required. Instead, it can be used to prepare and protect vulnerable points before a compatible membrane or protective coating is applied.
In KCS waterproofing systems, XT100 may be combined with Aquashield AS100 and, where specified, UV Reflector 101 to address different stages of roof and structural protection.
Key Features of Sealant XT100
XT100 is designed primarily for flexible sealing and detail treatment. Its role should be considered within the complete repair or waterproofing system rather than as a universal coating for every substrate.
Modified Polymer Formulation
Provides a flexible sealing material for suitable cracks, joints, gaps and other waterproofing details.
Flexible Detail Sealing
Helps accommodate normal movement in suitable joints and detail areas when correctly applied.
Transparent Light Blue Finish
Provides a relatively subtle finish that can make treated detail areas easier to inspect during waterproofing work.
Multiple Detail Applications
Can be specified for suitable roof cracks, joints, penetrations, fasteners, pipe gaps and other leakage-prone areas.
Weather Exposure Protection
Designed for suitable external sealing applications subject to correct preparation, application and system requirements.
Pre-Membrane Detail Treatment
Can be used to treat selected vulnerable details before application of a compatible waterproofing membrane.
Where Sealant XT100 Is Used
XT100 is used for selected sealing and waterproofing details across residential, commercial and industrial structures.
RCC Roof Cracks & Joints
Suitable cracks and joints can be treated before application of a compatible roof waterproofing membrane.
Expansion & Movement Joints
Selected joint details can receive flexible sealing treatment according to their width, movement and construction.
Metal Roof Fasteners & Joints
Used for suitable screw, bolt, overlap, seam and penetration details as part of a metal roof waterproofing system.
Pipe & Drain Penetrations
Suitable gaps around pipe penetrations, drains and service entries can be treated before membrane application.
Parapet & Roof Junctions
Helps treat suitable roof-to-parapet junctions, corners, transitions and other leakage-prone details.
Terraces & Balconies
Can be used for selected cracks and joint details before the specified waterproofing treatment.
Concrete Wall & Slab Details
Suitable non-structural cracks and construction details may receive XT100 sealing treatment after assessment.
Industrial & Warehouse Structures
Used for suitable leakage-prone details on industrial roofs, sheds and compatible structural surfaces.
Selected Water-Tank Details
May be used for suitable cracks, joints and penetrations in water-storage systems where the material and complete system are appropriate for the intended application.
How XT100 Works Within the KCS Waterproofing System
The three KCS product systems serve different functions. XT100 focuses on detail sealing, AS100 provides the flexible waterproofing membrane, and UV Reflector 101 can provide reflective and protective finishing where specified.
Sealant XT100
Suitable cracks, joints, penetrations, fasteners and leakage-prone details are treated before the main membrane system.
Aquashield AS100
Polyurethane liquid rubber coating used in selected systems to create a flexible, seamless protective waterproofing membrane.
UV Reflector 101
Solar-reflective protective coating that may be specified over suitable exposed roof systems for additional UV and solar-exposure protection.
Professional Sealant XT100 Application Process
The exact application method depends on the substrate and detail being treated. A typical KCS sealing sequence may include the following stages.
Inspection
Identify cracks, joints, penetrations, fasteners, leakage points, movement zones and existing coating conditions.
Surface Preparation
Remove loose material, dust, dirt, contaminants and deteriorated material as required for the selected sealing system.
Crack & Joint Preparation
Suitable cracks and joints are prepared according to their condition, width, depth and movement characteristics.
Primer Where Required
A compatible primer or bonding preparation may be required depending on the substrate and specified system.
XT100 Application
Sealant is applied to the prepared crack, joint, gap, penetration or other specified leakage-prone detail.
Detail Finishing
The applied sealant is finished as required to provide appropriate coverage and transition with the surrounding surface.
Membrane Integration
Where XT100 forms part of a larger waterproofing system, a compatible membrane such as AS100 may be applied after the required preparation and curing.
Final Inspection
Treated details are checked before the next waterproofing stage or final protective coating is applied.
Substrate & Application Considerations
RCC & Concrete
Cracks and joints should be assessed for depth, width, movement, moisture and structural condition before sealing.
Metal
Rust, loose coatings, oil, dirt, fasteners, seams and surface corrosion should be addressed before application.
Existing Coatings
Existing paint, bitumen or other coatings must be checked for adhesion and compatibility before XT100 is applied.
Movement Joints
Joint dimensions and expected movement should be assessed so the selected sealing detail is appropriate for the application.
Active Leakage
Active water entry may require temporary control or additional preparation before permanent sealing and waterproofing work.
Water-Storage Applications
Material suitability and intended-use requirements must be confirmed for water-storage applications, particularly where water-contact compliance is relevant.

It may be used for suitable fastener, seam, overlap, joint and penetration details on compatible metal roof surfaces after appropriate cleaning and preparation.
Can XT100 be used with Aquashield AS100?
Yes. XT100 can be used to treat suitable cracks, joints and leakage-prone details before Aquashield AS100 is applied as part of the specified waterproofing system.
Can XT100 be used around pipe penetrations?
Suitable pipe penetrations and service-entry gaps can receive sealing treatment where the substrate and detail are compatible with the specified system.
Can XT100 be used inside water tanks?
It may be specified for selected water-storage details where the material and complete waterproofing system are suitable for the intended application. Water-contact and potable-water requirements must be confirmed before use.
Does XT100 structurally strengthen concrete?
No. XT100 is a sealing material and should not be represented as a structural strengthening product. Structurally significant cracks or damaged concrete require appropriate assessment and repair.
Does XT100 require surface preparation?
