The storage and application of self levelling PU sealant affect the shelf life and usage. The shelf life of all given is understood to be 12 months from the date of manufacturing. It is to be kept in temperature from 5°C to
In the specific case of India, since practically the temperature rises up to 45°C to 50°C, the sealant is usable. Due to extreme heat or humidity, the skin formation time of the same may be little faster in those specific conditions. Although, the sealant can still be used with effectiveness.self levelling pu sealant
What Is A Polyurethane Sealant?
Polyurethane Sealant is basicly an insulating and grouting material. They can have ±25% movement capability. The flexibility ratio can be further increased as required. It is used for sealing, filling gaps, keeping water and air away from joints, absorbing the natural movements of building materials and increasing aesthetics.
Self levelling pu sealant is used for Sealing Purposes.
Shore A hardness up to 45 polyurethane sealants are classified as low modulus. It is used in joints between prefabricated building elements, in joints of rainwater collection pipes on roofs and in rain gutters, insulating joints between precast concrete blocks and sealing of joints of aluminum pipes in HVAC (ventilation) sector.
Polyurethane sealant is available in the market with the following names; Polyurethane construction sealant, polyurethane sealant, non-staining polyurethane sealant, UV resistant PU sealant, bubble-free polyurethane sealant and modified silicone sealant.
How to seal concrete joints?
Expansion joints must be sealed with a self levelling pu sealant, like Boss SL Self-Leveling Polyurethane Sealant or Boss LM low modulus Non-Sag Polyurethane Sealant (dependent on application), or an expansion joint strip, to prevent water from penetrating the joint and deteriorating the sub-base.

How to use self levelling pu sealant ?
Surface preparation: Grind the substrate with a wire brush or other equipment tool, and remove dust and friable particles.
Backer rod installation: Insert a fitting backer rod to the required depth. The diameter of the backing rods should be 20 – 30% larger than the joint width. If using a closed cell polyethylene backer rod pay attention when inserting the rod not to damage it for example by using a sharp tool like a screwdriver. Use a blunt tool to insert the backer rod.
Masking tape and primer application: If sharp and exact joint lines are required place a masking tape. Take care that the tape is well attached to the surface to avoid spread of the primer below the tape. Apply primerin the area where the sealant is supposed to be apllied later.
Sealant application: Fill the joint with sealant avoiding air entrapment. Remove excess material.
Make it look nice: Remove the masking tape before skin formation. Smooth the joint sealant with smoothing liquid for a perfect finish

What are some of the advantages of using Polyurethane sealants?
Polyurethane sealants offer many advantages, primarily versatility. PU sealants can be formulated into different kinds of products for a variety of applications, especially in large infrastructure construction projects. They can be used in various joints, such as expansion and deformation joints in the construction of buildings, tunnels, bridges, roads, and subways, as well as building projects for airports, railway stations, and power station projects.
PU sealants can also be designed for smaller application projects such as basement waterproofing, window and door installations, and swimming pool sealing. Sealants of different kinds have separate application areas and can be specified correctly based on project requirements and demands.
PU sealants offer strong bonding to wood, metal, and plastic, along with great flexibility (particularly at low temperature), recovery properties, and tear resistance. They rapidly develop strength before complete cure, helping to reduce downtime during application. PU sealants are also resistant in tough environments, both in terms of exposure to temperature extremes and in their resistance to chemicals. They are easily formulated into a variety of colors and can be overpainted after application.
