Concrete Floors: Dry-Shake Hardeners, Densifiers and Sealers

This seminar explains why concrete floor surfaces fail, compares dry-shake hardeners, silicate densifiers and sealers, sets out the correct timing and method for applying each, and shows how to specify abrasion resistance, flatness and appearance with the tests that verify them.

Learning objectives

1. Explain why concrete floor surfaces dust, wear and stain, and how finishing and curing set surface quality
2. Compare dry-shake hardeners, silicate densifiers and sealers by how they work and what they improve
3. Apply the correct timing and method for broadcasting dry-shake hardeners and for applying densifiers and sealers
4. Specify abrasion resistance, flatness and appearance requirements and the tests that verify them
