PU concrete, or polyurethane concrete / polyurethane concrete, is resistant to mechanical, chemical and thermal influences. Ideal for use in manufacturing, food and pharmaceutical industries.
What is the difference between epoxy and PU?
The main difference between epoxy and polyurethane is that epoxy flooring in general is harder whereas PU flooring is more flexible. PU coatings and self-levelling materials are also much more sensitive to moisture presence.
What is PU flooring?
What is PU Flooring? PU or polyurethane is the coating material that has been developed as an alternative for heavy industries usage and has ever since become quite a common flooring material. PU flooring is primarily known to have the excellent gloss and colour varieties.
How long does polyurethane last on concrete?
Urethane or epoxy top-coated floors should last 10 or more years if regularly maintained. However, severe scuff marks can take a toll on the gloss and the overall look of the floor. Now, consider re-coating the floor.
What is polyurethane mortar?
Urethane mortar is often called cementitious urethane because it does have cement properties in one of its components, which gives it some similar characteristics to that of cement. The benefit of this is that it expands and contracts similarly to a concrete substrate.
What are the disadvantages of polyurethane?
DISADVANTAGES AND LIMITATIONS:Poor thermal capability.Poor weatherability.Attacked by most solvents.Utilize toxic isocyanates.Flammable.
Which is stronger epoxy or polyurethane?
when it comes to hardness epoxies are much stronger but polyurethane are more scratch resistance. Polyurethanes do not bond well to concrete and do not exemplify the self leveling properties that epoxies do when applied to on these surfaces.
Is polyurethane good for concrete?
You can use polyurethane concrete sealers on either an interior or exterior concrete in order to create a transparent and non-yellowing durable finish. They are typically used as top coats over over an epoxy or acrylic sealers. Polyurethane (or Urethane) provides a superior resistance to abrasion and chemicals.
How much does it cost to polyurethane a concrete floor?
Polymer or polyurethane: These coatings cost $0.95–$1.10 per square foot, including materials and labor.
Is polyurethane better than epoxy for garage floor?
Newer polyurethane products do tend to perform better than epoxies, but they take twice as long to install as other options — up to four days to fully cure — and they run the risk of peeling and cracking because they must be applied relatively thinly due to their lengthy cure times.
How do you install polyurethane?

Is urethane cement breathable?
Urethane Cement is a breathable coating which allows the transmission of water vapour. For this reason, it is a more suitable solution for areas where the underlying concrete floor is subject to moisture, including low-lying areas near waterways or areas prone to flooding.
What type of plastic is polyurethane?
Polyurethanes are plastic polymers made by combining diisocyanates ( TDI and MDI) and polyols. There are literally hundreds of different types of polyurethanes and each is made in a slightly different way: Carbon dioxide is used as a blowing agent to create the soft, comfortable feel of a mattress or sofa.
