Jump to:
+44 (0)1525 718877 www.uk.weber

Application

The system can be covered with:

  • Epoxy resin.
  • Polyurethane (can be left uncoated if 4610 is used).

Minimum substrate strength: 1.5 N/mm² for weberfloor 4360.

Minimum substrate strength: 1.5 N/mm² for weberfloor 4610 and weberfloor 4655.

Description

Fibre-reinforced, rapid drying, self-smoothing floor screed system ready to receive epoxy or polyurethane coatings (when used with 4655 or left uncovered when used with 4610). Manufactured in accordance with BS EN 13813: 2002. Complies with BS 8204-7. Not for use with underfloor heating.

Components:

- Primer/ Bonding coat (weberfloor 4716 primer):

  • Styrene acrylate dispersion which can be diluted with water. Designed for pre-treating all substrates prior to the application of weberfloor products.
  • Regulates the porosity of the substrate.
  • Improves the adhesion and flow of flooring products.
  • Reduces the formation of pinholes in the levelling layer.
  • For use on in-situ and pre-cast concrete, lightweight concrete, ceramics, stone, timber.

- Mesh reinforcement (weberfloor 4945):

  • Glass fibre reinforcement net with an alkaline ­resistant impregnation.
  • Specifically for use on weak substrates or in case the screed is laid non­-bonded.
  • Reinforces weberfloor base and renovation screeds in floating floor applications.

- Base screed (weberfloor base rapid 4360 - for use where required):

  • Rapid drying self-smoothing thick base screed.
  • Incorporates Low Dust Technology™, which provides a strong base layer for receiving tiles or a thin topping screed, and reduces the amount of waste and airborne dust produced during application.
  • Can be pump or hand applied.
  • Rapid drying, allowing an early overlay when compared to traditional sand/ cement or concrete screeds.
  • Low alkalinity.
  • Casein-free.
  • For use on concrete, sand/ cement screeds.

- Damp proofing membrane (weberfloor DPM - for use where required):

  • Two-coat epoxy resin damp proofing system.
  • Easy to apply onto concrete and cement based levelling compounds.
  • Suppresses the passage of moisture up to 98% RH.
  • Reduced project timescale, allows early installation of floor finishes.
  • Resistant to a wide range of chemicals.

- Top layer topping screed (weberfloor industry pro top 4610 or weberfloor industry rapid 4655):

  • Self-smoothing industry top screed and resin receiver.
  • Can be pump or hand applied.
  • For use in industrial areas.
  • Will require pre-treatment of weberfloor 4716 primer.

Weber will only guarantee the products which form the system. Where membranes/ DPM by others are used, these will require a guarantee by the membrane/ DPM manufacturer.

Please ensure movement joints coincide with the building and can be used to assist with sequencing of application.

Preparation/ Recommendations:

  • The substrate should be clean, free from dust, grease and other impurities that might prevent adhesion. All damaged and friable material should be removed. Leaving a good sound, solid substrate, this remedial work should then be a minimum 20 mm deep from the existing datum and 200 mm in length and width. This 200 mm should encapsulate the damaged area by a minimum of 50 mm. Should the damaged area be greater than 200 mm the excavation should always be a minimum of 50 mm past the furthest point.
  • Prior to the final floor finish being applied, please ensure the weberfloor is suitably protected once cured.
  • Reaction to fire clarification has not been determined/ tested and therefore this product is not suitable to be left exposed. For further details, please refer to table ZA.1.1 (page 22) of BS EN 13813 and contact Weber technical team. Prior to installation of Weber floor products, please consult with your local building control authority or equivalent to ensure a reaction to fire classification is not required - especially for onerous areas such as protected shafts, fire exits and fire corridors.

Please note that weberfloor fibre 4360 without 4610 or weberfloor industry rapid 4655 should not be used without a floor finish.

Product Reference

WeberSpec Industry Rapid Floor

Primer/ Bonding coat:

The substrate should be vacuum cleaned, prepared and primed with weberfloor 4716 primer, according to the manufacturer's instructions (e.g. mixing recommendations). Priming improves the screed’s adhesion to the substrate and prevents the formation of air bubbles and dewatering of the screed. If the screed is applied in more than one layer, each layer must be primed.
