Plywood & Screed Subfloor Preparation - Supplied & Fitted Across Kent
Every quality floor starts with a flat, sound subfloor. We lay 6mm or 9mm ply over uneven floorboards and apply self-levelling latex over concrete to give LVT, vinyl and laminate the perfect base to sit on.
Preparation for offices, shops and salons
Commercial floors usually arrive with years of old adhesive under worn carpet tiles or vinyl. We remove that residue, smooth and level the concrete with compounds, and take moisture readings before anything impermeable goes down. It is the part of a commercial fit most often missing from a cheap quote. Work can be planned for evenings or weekends, and larger floors done in phases. See floor screeding, commercial flooring and office carpet tiles.

Fitter's tip: Latex screed is rarely 'optional' under LVT - under-prep is the single biggest reason floors fail early.

Subfloor Prep questions
- Do I always need subfloor prep?
- No - over good condition chipboard or a flat screed, often not. But over old floorboards, tiles or uneven concrete, it's essential for LVT and vinyl.
- How long does screed take to dry?
- Standard latex screed is walkable in 2-4 hours and ready for LVT the next day. Deeper screeds need longer - we'll advise on the day.
- Does ply add a lot of height?
- 6mm ply is the standard - barely noticeable at door thresholds. We finish all transitions with proper bars.
