1 Extensive surface preparation, such as grinding, crack repair, and spall repair, can add as much as $2 per square foot to the overall cost of the floor. 2  If a full resurfacing is needed, expect to tack on another $2 to $3 per square foot (for a $4 to $5 per square foot increase). Typically installers put down a series of products including waterproofing, metal lathe, a concrete overlay and then the final finishing and sealing coats. 2  These applications can add another $2 to $3 per square foot to the cost of the floor.
1. Lecture - professor/teacher talks & you take notes as you listen. 2. Discussion - you interact w/ whatever the professor asks & put in your opinions/thoughts on topic. 3. Seminar - I think these are like classes for Freshmen in college who get an idea of what the career is about.
1.In a lecture, the professor dictates and the students take notes. In a seminar, the professor does not have as much of a role because he just oversees or guides the class. 2.Unlike a lecture, the subjects are widely discussed in a seminar. Moreover, new ideas and theories evolve through seminars.
