Sub-floor Preparation 101: Why Self-Leveling is Non-Negotiable
You've spent thousands on premium SPC flooring. You've picked the perfect color. But there's one thing that can destroy the entire project before the first plank is even laid: an uneven subfloor.
1. The 3mm Rule
Industry standards for rigid-core flooring like SPC state that the subfloor must be flat within 3mm over a 2-meter radius. If you have a "dip" or a "hump" larger than this, the click-lock system will be under constant stress. Eventually, it will fail, leading to separated planks or annoying clicking sounds when you walk.
2. What is Self-Leveling?
Self-leveling compound is a specialized cementitious mixture that, when poured, flows like water to find the lowest points of the floor. It creates a "table-top" flat surface that is the perfect foundation for any premium floor.
Frequently Asked Questions
Do I always need self-leveling? ＋
Not always. If your current cement screed is already very flat, you might only need minor "patching." However, most Malaysian terrace houses and older condos require it for a professional finish.
How much does self-leveling cost? ＋
In Malaysia, professional self-leveling typically costs between RM 1.50 and RM 3.00 per sqft depending on the thickness required.
