Technical Data

Typical Properties:

Resin Ratio

It is important the correct ratio of resin to aggregate is used.

Cube strength tests carried out in accordance with BS EN 1290 – 3: 2009 demonstrate that a 6.5kg sized resin bound binder will be 19% weaker than a 7.5kg resin bound binder when used with a standard 106.25kg aggregate mix.

Vuba Moisture Tolerant Resin Bound Binder is 7.2kg in size.

Colours

The surface colour is determined by the aggregate used within the mix. Refer to Vuba Aggregates for more information on available colours.

Curing Times

• The product is designed to cure for light foot traffic in 16-24 hours
• The product will gel much sooner, but maintain a tackiness until this point
• For vehicle traffic, we would recommend to leave 24-48 hours

Do not add any form of catalyst to this product.

Suitable Substrates

See the ‘Vuba Base Build Up’ Datasheet for advice on the correct base and sub-base build up for use with Vuba Resin Bound Binders.

Tarmac

Vuba Resin Bound Surfacing

The thickness required for your resin bound surfacing is dependent upon the usage, and the size of the aggregate in the blend you choose. Please see the following as a general guide:

• Pedestrian Traffic - 12mm to 15mm
• Parallel Driveways - 18mm
• Turning Vehicle / Heavy Traffic 18mm to 21mm

Contact our technical team for advice and specification on your project on 0113 2455450 (option 2) or send a message to [email protected]

Binder Course

Minimum 50mm depth of open grade asphalt 100/150 pen to BS EN 13108-1:2006.

Sub Base

150 – 225mm depth of well compacted non-frost susceptible Type 1 granular sub base.

Sub Grade

Top soil stripped back until organic and vegetative material has been removed.

Advice: Open grade Tarmacadam is the base recommended by Vuba for all new projects which are to receive vehicle traffic. This base has excellent flexural strength, is fully permeable and interlocks excellently with resin bound surfacing.

Concrete

Vuba Resin Bound Surfacing

The thickness required for your resin bound surfacing is dependent upon the usage, and the size of the aggregate in the blend you choose. Please see the following as a general guide:

• Pedestrian Traffic - 12mm to 15mm
• Parallel Driveways - 18mm
• Turning Vehicle / Heavy Traffic 18mm to 21mm

Contact our technical team for advice and specification on your project on 0113 2455450 (option 2) or send a message to [email protected]

Binder Course

Minimum 100mm concrete, finished to a tamped or brushed finish. Compressive strength to be 30N/mm² and tensile strength 2.5N/mm². Relative humidity to be below 85% RH in accordance with BS 8205.

Sub Base

150 – 225mm depth of well compacted non-frost susceptible Type 1 granular sub base.

Sub Grade

Top soil stripped back until organic and vegetative material has been removed.

Concrete is susceptible to cracking / joint movement which can reflect through into the in situ applied resin bound surfacing. Care should be taken to ensure joints / cracks are treated or reflected through into the resin surfacing.

Vubagrid

Sub Base

150 – 225mm depth of well compacted non-frost susceptible Type 1 granular sub base.

Sub Grade

Top soil stripped back until organic and vegetative material has been removed.

Concrete is susceptible to cracking / joint movement which can reflect through into the in situ applied resin bound surfacing. Care should be taken to ensure joints / cracks are treated or reflected through into the resin surfacing.

Usage Guidance

Three principles create the high level of hydrophobicity of Vuba Resin Binder MT and it is important these are observed during usage:

• The first is the rate of reaction, this is controlled upon catalysis during manufacture and further catalyst should not be added
• The second is the ratio of hydrophobic additives in the product, and therefore the product should not be diluted
• The third is the ratio of A to B, so it is important this ratio is not altered for application

Moisture Damage:

• White colouring and foaming on the surface is symptomatic signs of moisture damage that is most commonly associated with moisture damage in resin bound surfacing
• However, it is possible for projects to have suffered moisture damage but it is not visible on the surface, only after taking a core sample
• Different types of moisture damage cause different signs of failure. Although resistant to moisture damage, our binder can still suffer a loss of binder from precipitation, and care should be taken to avoid applying this product in rainy conditions

Preparation & Priming Guidance

Preparation:

• Prepare the surface as standard for a resin surfacing application
• The surface ought to be dry prior to application
• It is preferred and the system is most effective when applied on to a permeable base

Priming:

• We do not recommend to wet prime a base prior to application of a Vuba Resin binder MT screed
• However, we would recommend using an epoxy primer and seeding for porous cementitious bases

Humidity:

• Vuba Resin Binder MT is capable of withstanding a humidity of >95%

Temperatures:

• It is recommend the ambient temperature is 5°C and rising during application

Grades:

• This product is pre-catalysed to suit the season
• You Must use the product in the correct temperature range
• The curing rate of this product impacts the resistance to moisture
• Too fast curing will reduce moisture tolerant properties
• Do not add any form of catalyst to this product

Limitations

The product is designed to perform as a binder for resin surfacing in conditions of high humidity, or in the possibility of light precipitation. All projects should be planned to take place during good weather.

Shaling - The surfacing may be affected by the shaling action of tyres when vehicles are turning in confined spaces. Tyres must not be turned when in a slow turning or static position. Wheels should not be regularly turned in confined spaces. Debris and loose stones must not be trafficked on to the resin bound surface, as this may result in de-lamination of the screed.

Regular inspections should be carried out to ensure early detection of damage should this occur.

Cracking – Resin bound surfacing is typically applied as a seamless finish, and as a result could suffer from cracking over time. There are various types of cracking: Reflective Cracking (Cracking as a result of movement or cracking in the base which is reflected in the resin bound surface); Re- Entrant Cracking and Subsidence Cracking. See ‘Vuba Resin Bound Warranty’ document for more information.

How to Apply a Resin Bound Sealer

This guide shows you how to make a sealer for resin surfacing using our Resin Bound Binders.

A Resin Bound Sealer can be applied to both old and new resin bound surfacing for the following reasons:

• Improve surface strength
• Rejuvenate and colour enhance
• Help to bring uniformity

The Resin Bound Sealer is solvent based, high strength and modified for easy roller coat application on to resin surfaces. The Resin Bound Sealer is simple to make and applied to the surface using a brush and a roller.

Materials Needed

• 7.5kg Vuba Resin Bound binder
• 1.5ltr white spirit
• Scuttle bucket
• Medium pile roller
• Paint brush
• Accelerex (if required)
• Crushed glass (if required)

Preparation

Ensure the surface is clean, dry and free from contamination. The surface must be dry or the Resin Bound Sealer will react with excess moisture and blooming will occur. This will look like pale foaming on the surface, and will leave an unsightly finish. Mark out the area required to apply first, to ensure even distribution.

Mixing

STEP 1

Addition Quantities of White Spirit:

• 350ml addition to a 1.75kg Resin Binder
• 1400ml addition to a 7kg Resin Binder
• 1500ml addition to a 7.5kg Resin Binder

White spirit must be added to the Part A and mixed until fully blended.

Please note: Vuba Trade Moisture Tolerant Resin Bound Binder is supplied pre-catalysed - Do not add any form of catalyst to this product.

STEP 2

Pour the ‘Activator B’ into the larger ‘Resin A Tub’ and mix both components for 90 seconds.

STEP 3

Pour the mixed Resin Bound Sealer into a scuttle ready for application.

STEP 4

Apply using a medium pile roller, ensuring not to allow pooling. The resin will sit on the surface and begin to seep into the cavities after 15-20 mins. Oversaturation may remove the permeability of the system.

STEP 5

Scatter crushed glass on the top surface – this will add anti-slip to the surface. (OPTIONAL)

STEP 6

Apply a second coating for weak surfaces, which require additional strengthening.

STEP 7

Allow to cure for 48-72 hours depending upon temperature.
