Start with the floor assembly
Screed vs Self-Levelling Compound is not a one-product answer. The existing substrate, intended covering, loads, moisture condition and junctions determine the method. A useful scope records what is present, what must be removed, the target level or performance, and how completion will be checked.
Decision module
Use case
selecting a correction method.
Evidence
Record levels, condition, moisture indicators and the intended finish rather than selecting from appearance alone.
Escalate
Movement, contamination, active leaks or uncertain structure need resolution before a finish is concealed.
Working process
- Inspect
Confirm substrate, access, edges, levels and visible failure. - Design the scope
Match preparation and build-up to the finish manufacturer’s requirements. - Verify
Record preparation, application conditions and readiness for the next trade.
Limitations and site preparation
Important constraints include substrate survey and finish tolerance. Clear access and identify services. Product drying times are conditional, not promises: temperature, ventilation, thickness and substrate moisture affect readiness. Hidden defects can change the scope after removal or testing.
Screed Flooring coordinates the floor-build-up decision. Specialist delivery is confirmed after assessment, and the delivery team remains responsible for its own inspection and written scope.
Questions answered
When is screed vs self-levelling compound appropriate?
It may suit selecting a correction method. The correct scope depends on an inspection, measurements and the specified finished floor.
What should be checked before work starts?
Check substrate survey and finish tolerance, site access, adjoining finishes and the product or system requirements before confirming a method.
Can you confirm a solution from photos alone?
Photos help with triage, but depth, moisture, bond, contamination or movement may require on-site testing before a reliable scope is issued.
