About this Blog

MAPEI Tech Talk is a blog devoted to the flooring and construction industry. It is updated on a regular basis by the social media team at MAPEI Americas, and it will feature guest bloggers occasionally as we provide you with viewpoints from across the industry.
We also may post on other blog pages and then let you know about those postings in this blog. Plus, our Technical Services team will make sure you’re up-to-date on our products and the latest methods for installing them.

While MAPEI Tech Talk focuses on topics of a mostly technical nature, it does so in a less structured, more immediate manner than “official” channels like our technical data sheets (TDSs) and technical bulletins.
We make every attempt to ensure that information provided here is consistent with those documents, but in the event of a contradiction you should go with the TDS and/or technical bulletin.

Stop by often, share this blog with your friends and contacts, and interact with us through your comments and questions.
