Polyurea Joint Filler
Polyurea Expansion Joint Filler
Concrete Crack Grouting Injection Material
Polyurea joint filler is a specialized formulation designed to fill expansion joints in different structures, such as buildings, bridges, highways, and floors. It is made from a combination of polyurea polymers, which offer exceptional durability, flexibility, and chemical resistance. The filler is applied to the joint, providing a seamless and flexible seal that accommodates movement while preventing water infiltration, debris accumulation, and potential joint damage.
product information
PG series Polyurea Joint filler is an environmentally friendly and durable option for concrete repair. It has excellent physical and chemical properties, including high elasticity, low water absorption, and strong bonding in wet conditions. It can also improve the tensile strength of concrete defects while plugging leaks and does not shrink after curing.

What are the key benefits of using Polyurea Joint Filler?
Benefits include rapid curing times, excellent adhesion, flexibility, and resistance to abrasion, chemicals, and weather conditions.
Is Polyurea Joint Filler suitable for outdoor use?
Yes, polyurea caulking has strong UV resistance, but we still recommend covering the construction surface exposed to sunlight with sand or other coatings.
What surface preparation is required before applying Polyurea Joint Filler?
Surfaces should be clean, dry, and free of contaminants. Proper surface preparation might include grinding, sandblasting, or other mechanical means to ensure good adhesion.
How does Polyurea Joint Filler compare to epoxy joint fillers?
Polyurea joint fillers typically offer greater flexibility, and better chemical resistance compared to epoxy joint fillers.
What is the typical lifespan of a Polyurea Joint Filler?
If used properly, polyurea caulk can theoretically last for more than 20 years, and due to its excellent durability, its service life is generally longer than traditional caulk.
Are Polyurea Joint Fillers environmentally friendly?
Many polyurea joint fillers are low in VOCs (volatile organic compounds), making them an environmentally friendly option compared to other fillers.
How is Polyurea Joint Filler applied?
Application methods can vary but often involve mixing and pouring the filler into the joint or using a specialized application gun. Follow manufacturer instructions for best results.
Can Polyurea Joint Filler be used for repair work?
Yes, polyurea joint filler is excellent for repairing damaged or worn joints in concrete floors due to its strong adhesion and flexibility.
Does Polyurea Joint Filler require a primer?
