What is joint sealing?
Joint sealing prevents unwanted surface water and contaminates like spent fuel or oil entering into the concrete or asphalt structure via the expansion or contraction joints. The sealant will move with the concrete or asphalt whilst providing a constant seal against the elements and any unwanted surface spillages.
What is PU sealant used for?
It is perfect for bonding and sealing panels. It is also a high quality joint sealant, being used in road and bridge building, as well as industrial flooring applications.
What are the two types of sealants?
The 4 chemical types of sealants which display elastomeric properties are following: Polysulfide sealants. Silicone sealants. Polyurethane sealants.
What is better silicone or polyurethane?
Generally speaking, silicone sealants are more versatile and flexible than polyurethane sealants and they work better in most environments. The inorganic composition means that silicone is resistant to UV rays, making it a better option than polyurethane sealant, which will eventually revert back to its natural form.
Is there a sealer for concrete?
There are two main types of concrete sealers: film-forming sealers and penetrating sealers. Film-forming sealers include acrylics, epoxies, and urethanes that form a coating on the surface of the concrete. This type of sealer is sometimes referred to as a topical concrete sealer or a coating.
What is sealant made of?
Sealants are made of a medical grade resin, and are similar to composite, or white filling material for when patients have cavities filled.

What kind of sealant is HS-1 SL?
HS-1 SL is a one-part, self-leveling hybrid sealant, developed with silyl-modified polymer (SMP) technology. It cures under the influence of… ASPHALT EXPANSION JOINT is the “original” expansion joint filler. It is composed of a blend of asphalts and mineral fillers…
What kind of sealant will bond to porous surfaces?
Sikaflex polyurethane sealants will bond to more surfaces, particularly porous substrates such as concrete and masonry, without the use of a primer. It is an accepted fact that Sikaflex polyurethane sealants have superior wetting action in achieving a bond to various joint substrates under jobsite conditions.
