Because of its flexibility and durability, polyurethane caulk is widely used in the construction of buildings. What's more, it makes an excellent coating for wood surfaces. Its resistance to scuffing and abrasion have helped polyurethane caulk become a popular coating for wooden floors.


While it comes with a steeper price tag than other types of caulk, you will find that polyurethane caulk is well worth the additional cost. In addition to being extremely flexible, this type of caulk is very resilient and is often able to last a lifetime. Also, once it dries, the caulk produces an easily paintable surface. Just make sure to have the proper tools on hand when applying your polyurethane caulk.
