Natural stone materials such as marble and granite are widely used in modern construction due to their elegance, durability, and premium appearance. They are commonly found in façades, cladding systems, flooring, countertops, entrance lobbies, washrooms, monuments, and high-end architectural finishes.
However, many building owners, contractors, and architects have experienced a common and costly problem after project completion: unsightly staining and discolouration around sealant joints.
In many cases, the issue is not the stone itself—it is the sealant that was selected for the application.
Choosing the correct sealant is critical to preserving the appearance and durability of marble and granite installations. This is where MS-2000 Modified Hybrid Sealant Technology provides a significant advantage.
Understanding Why Marble and Granite Become Stained
Natural stones are not completely impermeable materials.
Although granite is generally denser than marble, both materials contain microscopic pores and capillaries that can absorb oils, plasticizers, solvents, and other low molecular weight compounds from certain sealants.
When a conventional sealant is applied, these compounds can migrate from the sealant into the surrounding stone over time. This phenomenon is commonly referred to as:
- Plasticizer migration
- Oil bleeding
- Sealant creep
- Edge staining
- Stone contamination
The result is often visible as:
- Darkened edges around joints
- Permanent yellow or brown staining
- Oily halos around sealant lines
- Uneven colour variation in the stone
- Reduced aesthetic appearance of premium finishes
Unfortunately, once staining penetrates the stone, removal is often difficult, expensive, or impossible.
Why Conventional Sealants Sometimes Fail
Many low-cost sealants contain ingredients that improve flexibility and workability but can migrate into porous substrates over time.
Common problems encountered with inferior sealants include:
1. Stone Staining
Plasticizers and oils migrate into natural stone causing permanent discolouration.
2. UV Degradation
Exposure to sunlight can cause cracking, hardening, chalking, or colour fading.
3. Adhesion Failure
Poor adhesion to stone, metal, glass, or concrete may result in gaps that allow water penetration.
4. Shrinkage and Joint Cracking
Some sealants lose volume during curing, creating visible gaps and reducing weatherproofing performance.
5. Loss of Elasticity
Thermal movement causes expansion and contraction of building materials. Inflexible sealants can crack or debond under movement.
6. Dirt Pick-Up
Certain sealants remain tacky and attract dust and pollutants, causing unsightly joints.
7. High VOC Emissions
Traditional sealants may release higher levels of volatile organic compounds (VOCs), affecting indoor air quality and green building objectives.
How MS-2000 Solves These Problems
MS-2000 Modified Hybrid Sealant Technology has been developed to provide superior performance across a wide range of construction applications while overcoming many of the limitations associated with conventional sealants.
Non-Staining Performance for Marble and Granite
One of the most important advantages of MS-2000 is its proven suitability for natural stone applications.
Independent testing demonstrated that MS-2000 produced no surface staining on both marble and granite substrates under standard conditions, heat ageing conditions, and UV exposure conditions. This makes it an ideal choice for architects, façade contractors, and stone installers who need confidence that the appearance of premium stone finishes will be preserved.
Excellent Adhesion Performance
MS-2000 demonstrates excellent adhesion and cohesion properties, maintaining bond integrity even under cyclic movement conditions on both mortar and aluminium substrates. This helps ensure durable and weather-tight joints in demanding construction environments.
Outstanding Weather Resistance
Building joints are continuously exposed to sunlight, rain, humidity, and temperature fluctuations.
Testing showed that MS-2000 exhibited no cracking after accelerated UV weathering and cold-temperature bend testing, making it suitable for both interior and exterior applications.
Class 50 Movement Capability
Modern façades and building envelopes experience significant movement caused by thermal expansion, wind loading, and structural deflection.
MS-2000 has been tested for Class 50 cyclic movement performance, providing confidence that joints can accommodate movement without bond failure.
Low VOC and Green Building Compliance
Sustainable construction is becoming increasingly important across commercial and institutional projects.
MS-2000 has been tested with a VOC content of only 10 g/L and complies with LEED v4 and LEED v4.1 low-emitting material requirements, supporting healthier indoor environments and green building initiatives.
