Used both as a primary screed on new-build and as a levelling overlay on existing floors prior to a new finish going down. ### Who it's for Anyone laying a sensitive floor finish, tile, vinyl, LVT, engineered timber, polished concrete, resin. All of these require an SR2 substrate (typically ±3mm under a 2m straight-edge). Floor finish installers will refuse to start on out-of-tolerance floors, and rightly so. ### When it's needed New-build over insulation. Refurbishment over an old screed that has worn, cracked or sagged. Extensions where the new slab needs matching to the existing floor level. Commercial change-of-use where the existing floor was specified for a different finish than the new tenant wants. ### Why a professional matters Levelling looks like a thin overlay job until you realise the product, the thickness, the bond to substrate, the joint detailing and the dry-time all have to be right. We've remediated more failed DIY-store self-leveller jobs than we can count. The Cost Of Getting It Wrong ## What Out-Of-Tolerance Floors Cost You Floor finish installers don't accept rough substrates. Here's what happens when the levelling is wrong. ### What Goes Wrong -! #### Tile lippage and cracked grout Out-of-flat substrate transfers straight into the tile. Lippage between tiles, cracked grout joints, and a finished floor that looks every bit as bad as the substrate beneath it. -! #### Vinyl and LVT telegraphing Every bump and hollow in a substrate telegraphs through thin floor finishes within months. A floor that looked perfect on handover looks tired by spring. -! #### Polished concrete failures Polished or resin finishes are the most unforgiving floor finishes of all. SR2 minimum substrate flatness is non-negotiable for these, and most existing floors don't get close. ### Common Mistakes - × #### Using the wrong levelling product Bagged self-smoothers from the merchant work for 5–10mm corrections. Liquid screed works for full pours. Putting one in the other's job creates failures. - × #### Skipping the priming coat Self-levellers and liquid screed both need primed substrates. Skip the primer and you get debonding within months. - × #### Levelling without checking substrate condition Levelling a cracked, friable or contaminated substrate is futile. We check substrate first, remediate where needed, then level. Our Process ## From Enquiry To Handover 01 ### Quick Phone Quote Call us with postcode, area and timing.

Why It Matters ## The Benefits, In Concrete ### SR2 Laser-Flat ±3mm under a 2m straight-edge, the standard every floor finish installer wants and every spec demands. ### Fast Turnaround Liquid levelling pours up to 2,000m² per day. Self-smoothers correct localised areas in hours, not days. ### Compatible With Every Finish Tile, vinyl, LVT, engineered timber, polished concrete, resin, every floor finish goes down without remediation. ### Permanent Correction Properly bonded and primed, the levelling layer is permanent, no telegraphing, no debonding, no return visits. ### Eliminates Finish Rectification Cost of levelling once is a fraction of the cost of lifting and replacing a failed floor finish later. ### Handover To The Next Trade Documented flatness check, primed and ready, sign-off so the floor finish installer can start on schedule. Technical Detail ## Levelling Methods, Materials & Tolerances Different floors need different levelling approaches. Here's how we decide. ### Liquid screed vs self-smoothing compound Liquid screed (calcium sulphate or cementitious) for full pours from 25mm to 65mm. Self-smoothing compound (cementitious, polymer-modified) for thin overlay corrections from 2mm to 15mm. Choice depends on existing level variance, finish weight, and timeframe. We specify on the survey. ### Flatness standards explained SR1 (±3mm under a 3m straight-edge), premium, used for specialist finishes. SR2 (±5mm under a 3m straight-edge, ±3mm typical), standard for most tile, vinyl, LVT, timber. SR3 (±10mm under a 3m straight-edge), utility floors only. We deliver SR2 as standard with SR1 available on specification. ### Substrate preparation and priming All substrates checked, vacuumed, primed with the appropriate product (epoxy primer for sealed substrates, acrylic primer for porous). Joints filled, cracks taped, expansion joints carried up through the levelling layer to prevent reflective cracking. ### Residential vs commercial levelling Residential: tile-ready kitchens, vinyl-ready bathrooms, LVT-ready living spaces. Commercial: retail change-of-use, office refurbishment, gym and leisure floors with high point-load. Specification differs, we size and mix accordingly. ### Drying and overlay timing Self-smoothers typically accept overlay finishes at 24–48 hours. Full liquid screed levelling needs 7–14 days before floor finish, subject to moisture testing. We provide the timing schedule on handover so the next trade knows when they can start.
