HydroCoat 1 Screed 2K

  • Self-Levelling Waterproof Strength: HydroCoat 1 Screed 2K is an epoxy and polymer-modified cementitious screed for levelling and waterproofing concrete substrates. Its flowing consistency supports application by pouring or pumping, resulting in an even, durable, lightly dimpled surface finish.
  • Rapid Hardening, Durable Performance: HydroCoat 1 Screed 2K hardens quickly to form a tough, abrasion-resistant wearing screed. Consequently, it withstands trafficking while allowing resin coatings and screeds to be applied within 4–24 hours.
  • Dense Matrix, Long-Term Protection: The cementitious matrix delivers low water permeability and high abrasion resistance. Therefore, it provides reliable waterproofing and surface durability in demanding internal environments.

Self-Levelling Cementitious Screed – Technical Overview

Applied to concrete substrates, HydroCoat 1 Screed 2K delivers effective levelling and waterproofing as part of an internal Type A system. As a result, it creates a durable base suitable for trafficked floor areas. The epoxy and polymer-modified formulation exhibits controlled flow, enabling application by pouring or pumping. Consequently, installers achieve a smooth, even finish across both level and sloping substrates.

HydroCoat 1 Screed 2K rapidly hardens to develop high early strength with minimal moisture content. Therefore, the system allows installers to apply subsequent resin coatings and screeds within short overcoat times.

The dense cementitious structure has low water permeability, even under pressure. As a result, the screed provides reliable waterproofing performance while resisting abrasion and wear. The screed can be applied over variable thicknesses, making it suitable for uneven substrates. It performs reliably on damp concrete and supports rapid programme progression in refurbishment and new-build internal floor applications.

This self-levelling cementitious coating forms the screed element of the Newton HydroCoat 1 System. When used with Newton HydroCoat 1 Render, it delivers a complete internal Type A waterproofing solution. It is particularly suited to basements, garages, warehouses, and car parks where both waterproofing and surface durability are required.

    FAQ

    FAQ

    What is a self-levelling cementitious screed?

    A self-levelling cementitious screed is a flowable cement-based material used to level, smooth, and waterproof concrete floors.

    Where should HydroCoat 1 Screed 2K be used?

    HydroCoat 1 Screed 2K suits internal floor areas such as basements, garages, warehouses, and car parks.

    Can HydroCoat 1 Screed 2K be applied to damp substrates?

    Yes. Installers can apply the screed to damp or saturated concrete without risking osmotic blistering in subsequent finishes.

    How thick can the screed be applied?

    The screed applies at thicknesses typically between 3 mm and 60 mm, depending on substrate condition and design requirements.

    How quickly can the screed receive resin coatings?

    HydroCoat 1 Screed 2K hardens rapidly and typically accepts resin coatings or screeds within 4–24 hours.

    Is HydroCoat 1 Screed 2K suitable for trafficked areas?

    Yes. The screed forms a tough, abrasion-resistant wearing surface suitable for trafficked internal environments.

    Does HydroCoat 1 Screed 2K form part of a Type A waterproofing system?

    Yes. When used with HydroCoat 1 Render, it forms a complete internal Type A waterproofing system in accordance with BS 8102:2022.
