Prepare and Set Levels

This Civil Construction part of the job covers surface treatment, priming, moisture barriers, bonding additives, screeds, and levelling. The reviewed Product evidence supports these roles, but Products differ in substrate, moisture, movement, exposure, cure, loading, and installation method. Match the selected Product to the project condition, then follow its technical data and obtain trades guidance when the scope or system compatibility is uncertain.

Choose a Product in this part of the job by matching its evidence to the substrate, defect, exposure, movement, loading, moisture, and required finish. The category or Product title is only a starting point. Compare technical limits, preparation, mixing, application, cure, and compatibility before specifying a civil system.

Preparation depends on the selected Product, but the interface must be sound and suitable for the next operation. Check cleanliness, profile, moisture, temperature, geometry, access, and defects, then follow the manufacturer's sequence. If repair or water control is incomplete, resolve that earlier condition before starting this part of the job.

No. This part of the job is a job guide for supported Product roles, not a universal specification. Civil conditions vary by substrate, loading, water exposure, movement, design, and service environment. Use the supported Product list as a shortlist, then verify the actual condition, system design, and technical instructions before purchase or installation.

Verify the Product evidence, technical data, substrate preparation, environmental limits, mixing or installation method, cure window, coverage, and compatibility with adjacent systems. Confirm the project design and required performance with the responsible trade or engineer. Record any unresolved fit, exposure, or accessory question for trade review before publication.
