Answers to our FAQs

  • Why is a Polyurethane resin better than an epoxy Resin?

    Polyurethanes are quicker curing, especially at lower temperatures, are less affected by extremes of temperature and offer greater flexibility. They are also less affected by age embrittlement and less prone to debonding. Epoxies are generally brittle in nature.

  • Why is Resin Bound SUDS Compliant?

    Resin Bound is permeable as it has many voids across its entire surface area. The water is able to soak through the surface, filtering through the voids and drain away.

    The sub base must also be SUDS compliant therefore we have a specific SUDS base build up specification detailing the requirements.

  • What Type of Mixer is required for a Resin Bound application?

    We recommend that you use a forced action mixer for best results.

  • What temperatures can Resin be applied at?

    Installation should NOT proceed if
    -the relative humidity is outside the range of 30%-85%
    -the surface temperature is less than 3C above the dewpoint of the measured air temperature and the relative humidity.
    -the operating temperature and road surface temperature and/or air temperature is outside the range of 10C-35C

  • Is a primer required prior to Resin application?

    On good surfaces a primer is not required, but on a friable or dusty surface then we do recommend that the surface is brushed and primer is applied. Primer is best applied with a roller and typical application is 150gsm. The final surface should appear smooth and free from any foreign particles. The temperature when applying primer shoudl be between 10C-35C with 15C-18C optimum for easy application.

  • How do I Install Resin Bound?

    In simple terms, the two resin components are first mixed together using a drill and paddle. The resultant resin is then poured into a forced action mixer that has be pre-charged with the selected aggregate. The resin and aggregate are then mixed until all of the aggregate has been fully coated. This mix is then transported to the application area and roughly distributed. Finally it is compacted and finished using a trowel.

  • What thickness do I install Resin?

    It really depends on the end use of the installation but we recommend:

    18mm - for a standard driveway - with light to medium traffic (daltex uvr system installed to BBA guidelines).

    15mm - if the installation is to be used by pedestrians only or the sub base is strong and sound and can withstand the expected loads. Please note this does not meet BBA approved standards.

    25mm - for an installation area that is expected to withstand heavy vehicles

    If you are unsure as to how thick you should install the system please contact us.

  • How much aggregate will we need for one pack of Daltex UVR resin?

    The suggested mix design for Daltex Bound UVR Plus resin 7.5kg is
    3 x 25kg bags Daltex 2-5mm, 1 x 25kg Daltex 1-3mm and 1 x6.25kg of C52 sand

    The suggested mix design for Daltex Bound UVR resin 6.5kg is
    3 x 25kg bags Daltex 2-5mm, 1 x 12.5kg Daltex 1-3mm and 1 x6.25kg of C52 sand

  • Is Resin Bound UV resistant?

    Yes – Daltex UVR resin is an aliphatic polyurethane system which is highly light stable and is exceptionally resistant to discolouration after exposure to light. It is best suited for use with light coloured aggregates or other aggregates where colour stability is a key requirement.
