New to floor leveling?
Start with the essentials.

What is self-leveling concrete?

Self-leveling concrete is a flowable, cement-based material used to flatten a prepared subfloor. Most products are underlayments that need a floor covering, rather than a structural replacement for concrete. Read the complete self-leveling concrete guide.

How much self-leveling concrete do I need?

Your floor area, average pour depth, and product’s rated coverage determine the bag count. Add a suitable waste allowance and round up to whole bags. Use the material calculator with the coverage on your product’s data sheet.

Do I need primer before pouring?

Most self-leveling systems require a compatible primer. The substrate and product instructions determine which primer to use and when to pour. Check the primer guide alongside your manufacturer’s instructions.

Can I leave it as a finished floor?

Standard underlayment usually needs a floor covering. For an exposed finish, choose a product specifically rated as a wearing surface. The underlayment guide explains the difference.
