Primers, Preparation & Reinforcement

Wykamol & Newton – Professional-Grade Substrate Prep and Detailing

Clever Shield supplies Wykamol and Newton primers, lime inhibitors, jointing/reinforcement tapes, and ancillary prep products to ensure optimal adhesion, detailing, and substrate readiness before applying liquid or sheet waterproofing systems. Proper preparation extends service life, prevents failures, and completes a BS 8102-aligned waterproofing specification.

Why Proper Surface Preparation Matters

• Maximises waterproofing performance – promotes strong adhesion and seamless membrane application.

• Prevents bonding issues – reduces risk of blistering, peeling, or edge-lift.

• Controls free-lime leaching – protects membranes and drainage components.

• Works in real-site conditions – many systems are damp-tolerant and rapid-curing for efficient turnaround.

Newton – Surface Preparation & Priming

• HydroSeal 903 Primer – adhesion promoter for cementitious/liquid systems; helps mitigate out-gassing on porous substrates.

• CDM 906 Lime Inhibitor – controls free-lime deposition to protect Type C (CDM) components and finishes.

• Reinforcement & Jointing Tapes – double-sided lap tapes, overseal tapes, mesh/rope tapes for corners, laps, penetrations, and changes of plane.

Best for:

• Below-ground structures (basements, foundations)

• Concrete repair & preparation prior to waterproofing

• Construction joints, service penetrations, perimeter details

Wykamol – Primers, Preparation & Reinforcement

• Sureprime (Premium Performance Primer) – primer for compatible DPM/gas/waterproof membranes; moisture-tolerant, fast to apply.

• Membrane Tapes & Accessories – double-sided joint tapes, overseal tapes, fibre/fleece and corner strips, gas tapes, and butyl rope for fixing heads and tricky details.

• Ancillaries – fixing plugs, sealing tapes, and accessories to deliver a complete, reliable installation.

Best for:

• Internal/external damp-proofing and cavity-drain systems

• Gas-protection membranes and laps/joints

• Corners, wall/floor junctions, and high-movement or high-moisture details

When to Use Which

• Primers – on porous or challenging substrates to improve adhesion and reduce pinholing/out-gassing.

• Lime inhibitor (Newton CDM 906) – where fresh concrete or free-lime could compromise membranes/drainage.

• Reinforcement/jointing tapes – at laps, terminations, corners, penetrations, and transitions between materials.

• Ancillaries (plugs, rope, seals) – to maintain continuity and watertightness at fixings and interfaces.
