About ChemSeal PU
ChemSeal PU is a high-performance & low-modulus elastomeric sealant. It is particularly designed to be used in movement joints, specifically in structures where flexibility is a must. This product is one product of Sika’s extensive line of sealants as it’s known for its high quality & durability. Its polyurethane-based formula provides excellent adhesion to a variety of materials, including concrete, brick, wood, & metal.
Key Applications of ChemSeal PU
Movement & Expansion Joints: One of the main uses of ChemSeal PU is to be applied over movement & expansion joints. These are some kinds of gaps that are intentionally left between some sections of a structure to allow for expansion, contraction, or any other movements caused by environmental factors. The low-modulus property of ChemSeal PU will allow it to stretch & compress effectively to accommodate significant joint movement without causing any crack or losing adhesion.
Sealing Concrete Elements: ChemSeal PU is often used for sealing horizontal & vertical joints, particularly in concrete structures, such as sidewalks, parking garages, & panels. Out of its strong adhesion & weather-resistant properties, it ensures long-lasting protection against water infiltration that can cause damage over time.
Waterproofing Windows & Doors: This sealant material is widely used in waterproofing applications, especially around windows & doors. ChemSeal PU helps prevent drafts, leaks, & moisture ingress to maintain the structural & thermal integrity of any building.
Industrial & Commercial Structures: Large-scale industrial & commercial buildings also depend on ChemSeal PU for sealing joints’ movement in walls, floors, ceilings, & much more. Its UV resistance & ability to stand against varying temperatures make it an ideal option for both indoor & outdoor environments.

Joint Size: Make sure that the joint’s width & depth are within the recommended specifications and requirements for ideal performance.
Surface Preparation: All surfaces should be clean, dry, & free of any contaminants. For porous substrates, primer may be required.
Curing Time: ChemSeal PU begins curing once it is exposed to moisture in the surrounding air. Full curing times may differ depending on the joint size, temperature, & humidity.
Where Can You Purchase ChemSeal PU?
While there are many types of sealants available in the market, there are few that offer the same combination of flexibility, durability, & easy usage as ChemSeal PU. Its ability to handle large joint movements differentiates it apart from typical silicone or acrylic sealants. Moreover, its compatibility with a variety of substrates makes it an ideal option for professionals.
You can find ChemSeal PU easily available inside construction supply retailers, hardware stores, & online platforms. However, you have to make sure that you purchase it from a reputable & trusted supplier to guarantee the product quality. So, it is usually found in cartridges or sausages, depending on the scale of your project.
