Valtex is an ultra strength two component aliphatic polyurethane stone encapsulation binder manufactured by Vuba, for use with flint, quartzite, marble and granite aggregates.

Benefits of Valtex Resin:
- Valtex is 100% UV Stable
- FeRFA Compliant 7.5kg Resin Size
- 65 D Shore Hardness 
- 11 Years of Resin Manufacturing
- Extensively Tested Product 

We recommend Valtex Resin Binder for use with our 'Wonders of the World' Resin Bound Aggregates (Directly sourced and imported by Vuba). This binder is also suitable with other aggregate suppliers, such as Long Rake Spar.

Mechanical Properties:
The ratio of Isocyanate within the resin formulation can greatly affect strength. Valtex is manufactured to yield industry leading mechanical properties (see below). There is more information in the tab below entitled 'Resin Binder and System Strength'. 

Mechanical Properties Results
Shore D Hardness 65
Elgonation at Break 70%
Tensile Strength 13 MPa

Resin to Aggregate Ratio:
The FeRFA Resin Flooring Association now has a guide to the appropriate ratio of resin to aggregate. Our Resin is compliant, but other products in the industry are not. 

Product Size Resin / Aggregate Ratio FeRFA Compliant
Valtex Resin Binder 7.5kg 7.06% Yes
Competitor A 7kg 6.59% No
Competitor B 6.5kg 6.12% No

Why Not 7kg Resin Kits?
If you do not include the Binding Quartz in the mix, the ratio of 7kg Resin to Aggregate (100kg) is almost compliant. However, by taking away the binding quartz, you lose 20-30% of the strength of your system. 

Why not 6.5kg Resin Kit?
The small print is that this size of resin kit should ONLY be used with 3 x 25kg + 1 x 12.5kg Aggregate Kits. However, the typical 'middle-man' supplier will usually offer these with 4 x 25kg bags.

Why not add Binding Sand / Quartz?
Contractors and suppliers often leave out the 6.25kg Sand because it is a sandy colour, which ruins the appearance of lighter coloured silver blends. Even with golden mixes, the sand will absorb the resin, removing the sheen and leaving a sandpaper type finish. That is why we use DKI Quartz as our Binding Agent. A neutral translucent aggregate, 0.4mm - 0.8mm in size, perfect to create a strong matrix of sizes without negatively changing the appearance. 

When you order one of our Valtex 7.5kg Resin Binder Kits, you will receive a two part polyurethane resin. The resin is supplied pre-catalysed, therefore no requirement for additional mixing processes.

In low temperatures it is possible for you to purchase Accelerex, a 200ml accelerator designed to reduce curing time. 

Coverage Rate:
Each Resin Kit is designed to be mixed with 106.25kg of resin bound aggregate, and will cover approximately 3.50m2 @ 18mm nominal thickness. We would always recommend to allow for wastage and undulations in your surface by ordering 5-10% wastage.

DIY Kits:
It is possible to buy Valtex Resin Binder in a 'DIY' or '1 Bag' Kit Format. These are to be mixed with 26.56kg of Blended Aggregates from our DIY Resin Bound Range, and can be mixed with a Drill and Paddle or smaller 25 Litre Mixing Vessel, such as an 'SPE Mix It 25'.

2. Aggregates

The preferred method for testing aggregate suitability for use in resin bound systems is the Los Angeles Abrasion Test. The standard Los Angeles Abrasion Test subjects a coarse aggregate sample to abrasion, impact, and grinding in a rotating steel drum containing a specified number of steel spheres. The amount of weight lost as a percentage of its original value is referred to as the Los Angeles Coefficient. 

Other commonly used aggregate testing methods include PSV (Polished Stone Value), ACV (Aggregate Crushing Value), Aged Weather Testing and Field Testing.

All aggregates within this range have been testing using some or all of the above methods. A combination of Empirical and Field Test Data is used to create a detailed profile of each aggregate blend, including strength and suitability.

3. Resin Bound System

We test the complete resin bound system to International Standards ISO 178 and ISO 604. The tests carried out include Compression Testing, and Flexural Strength Testing using a Three Point Bend Test. The determining factors of the strength of any resin system is as follows:

a. Resin / Aggregate Ratio
b. Chemical Formulation
c. Aggregate Quality
d. Aggregate Size Grading

a. Resin / Aggregate Ratio
The FeRFA Resin Flooring Association has a guide to the appropriate ratio of resin to aggregate. The guidelines now state that a ratio of 7.06% of resin is required to the total amount of aggregate to be suitable as a resin bound surface. You can see details below:

FeRFA Compliance:



Resin / Aggregate Ratio

FeRFA Compliant

Valtex Resin Binder




Competitor A




Competitor B




The total size of resin kit is very important to the strength of a resin binder. Too little resin, and the system is underbound resulting in failure by loose stone. An underbound resin screed is highly susceptible to issues with lack of compaction, or thickness. A correctly bound system will be more forgiving for installers. 

b. Chemical Formulation
The ratio of Resin A to Hardener B has a determining affect on the overall mechanical strength of the resin bound system. We manufacture our binders using a High Isocyanate formulation. Isocyanate is the 'expensive' part of the formulation, essential for a high Shore D Hardness value. You can see typical Mechanical Properties for our Valtex and MarbleBound Resin Binders below. 

UV Stability:
Some suppliers offer a none UV stable form of resin because none UV or 'Aromatic MDI' resin is cheaper. This resin turns yellow / brown within hours of sunlight. We do not offer any resin binders which are not UV Resistant as part of our Ethical Ethos. You can see more about our Ethos here.  

C. Aggregate Quality
Aggregate quality is dictated by Cleanliness, Porosity, Size Uniformity and Aggregate Physical Properties. 

Therefore the quality of the aggregate is of vital importance when considering the Overall System Strength. For example, a fine, more absorbent aggregate can require up to 15% more resin to achieve saturation than other aggregates, our research has shown. 

We are an importer of aggregates and manufacturer of award winning resin bound systems - we are not a middle man, or a company that is brand new to supplying resin systems. We have spent 1,000's of hours visiting quarries throughout the world, and ensuring our aggregates undergo extensive testing. 

d. Aggregate Size Grading
The Blend Specification or Design has a large impact on the strength of a system. Addition of our binding quartz alone will increase the overall strength of a resin bound system by 20-30%, our research has shown. 

Similarly, a greater size variation of equal and suitable deviation creates a more compact final finish. Some of our blends will have a range from 0.4 - 0.8mm, 1mm to 3mm, 2-4mm, 2-5mm, 4-6mm. Greater compaction helps to prevent against stone loosening due to vehicle turning etc.

Cleaner and More Consistent:
Our aggregates demonstrate unrivalled cleanliness, size uniformity and colour consistency. The result is a significantly reduced chance of shading for contractors.

A Broader Range of Sizes:
The average Wonders of the World blend contains an industry leading 4 or 5 different aggregate size gradings per blend. Such a complete matrix of aggregates sizes, gradually grading up from 0.4mm up to 6mm in diameter throughout the full spectrum of the blend results in an easier to lay and more compact resin system with less chance of stone loosening. 

Binding Quartz:
Each blend within the range contains a Binding Quartz, a neutral translucent aggregate, 0.4mm - 0.8mm in size, perfect to create a strong matrix of sizes without negatively changing the appearance. This quartz increases the strength of the system by 20-30% compared to traditional resin bound surfacing without the 'sand'.

Before application of an Asphalt / Tarmac base, concrete or cellular grid, there should be in place the correct sub-base. This would be a minimum 150mm depth of well compacted Type 3 granular sub-base to SHW clause 805, or 4/40mm, 4/20mm crushed aggregate to BS EN12620 or locally available secondary or recycled aggregates which comply with the above specification blinded with 2/6.3mm graded crushed concrete aggregate to BS EN12620.

1. Concrete bay proportions should be ideally 1:1 and should not be greater than 3:2, long narrow strips of concrete will crack across the bay width and these cracks are likely to be mirrored in the surfacing. 
2. Open bay joints are likely to cause cracking in the surfacing and formation should be prevented by application of Polycrete repair mortar into the joints. Bays should be linked with steel mesh reinforcement, or if already in place, a surface grade mesh should be embedded in the surface using an epoxy bedding coat. 
3. Ensure that the concrete has a minimum design strength of C35 and that the concrete has a minimum compressive strength of 25N/mm2 before the surface is prepared, in accordance with BS 8500-2:2015. 

Ensure that falls are in place to an adequate drainage system when applying to an impermeable concrete base. Water will flow through the Valtex system and run across the concrete surface.

Asphalt (Bituminous Macadam):
The bitumen binder of asphalt concrete must have a pen value no greater than 100/150, when tested in accordance with EN 1426 Needle Penetration Test. It is advisable to use a harder grade of bitumen when machine application is possible and 70/100 pen (or harder) is preferred.

Bituminous materials with a higher pen value will be too soft and may deform in warm weather. Adequate compaction of the sub-base and base is essential to prevent cracking. A minimum 1 tonne “sit on” roller should be used when possible and the contractor must ensure that the construction is fully restrained at all edges to ensure dimensional stability.

Rainwater will flow through the permeable Valtex Resin Bound System, and through the open grade binder course. An integral drainage system is not required.

Cellular Grid:
We would recommend to use a cellular grid of 40-50mm in depth. The grid should be set on to a well compacted sub-base as laid out above. The cellular grid should then be filled with well compacted 4/10mm graded crushed aggregate to BS EN12620. The in-fill aggregate must be compacted to ensure the profile of the cellular grid is still visible, and capable of bonding to the resin bound system. 

Failure to compact the stones within the grid correctly will result in a slump of the resin bound material through the grid, causing delamination. 

Perimeter Edging:
Protect all edges abutting soft landscaping with brick, steel, timber or concrete to prevent damage to the surfacing. Edgings should be securely fixed to prevent movement. A flexible joint filler should be used at edgings where there is potential for movement to separate the surfacing from the edging.

Concrete Preparation:
Prepare concrete by mechanical means to provide a sound, clean, dry substrate that is free from laitance and suitable for application of the resin bound surfacing. Concrete should be primed prior to application using our Easiprime or Epiprime (and seeded with a 1.4 - 1.8mm quartz).

Asphalt (Bituminous Macadam) Preparation:
Allow the asphalt to oxidise for 7 days prior to application of the Valtex Resin Bound Surface. It is not a requirement to prime asphalt surfaces.

Suitable Mixing Equipment:
Large Pan Forced Action Mixer (Such as Baron E120 available from Vuba, here).

Suitable Resin Binder: 
7.5kg Valtex or 8kg MarbleBound depending upon the aggregate blend.

Mixing Guidance: 
1. Scrape all of the contents of Valtex / MarbleBound Resin Bound Surfacing B component into the larger Resin A component container and mix with a slow speed drill (≤ 450RPM) and MR2 paddle mixer attachment for 60-90 seconds. Overmixing will increase heat generation and reduce working time. 
2. Simultaneously, add 100kg of aggregate to the Large Pan Forced Action Mixer, Baron 120 Litre Capacity Mixer or similar approved. Followed by addition of the 6.25kg Binding Quartz. Do not allow the aggregate to rotate dry for more than 60 seconds. Excessive dry mixing forms dust in the mixer, which will darken the batch, resulting in shading issues throughout the application. 
3. Allow the aggregate to begin mixing and immediately add the mixed resin to the aggregate in the mixer until all the aggregate is evenly coated with resin. Mix for approximately 3-4 minutes. Overmixing will increase heat generation and reduce working time, in addition to shading issues.
4. Using a wheel barrow, discharge the mixed resin and aggregate onto the prepared surface, level and smooth. Ensure to compact to even firm composition.

Application Advice:
1. Finish the surface with a suitable float. Vuba Solvent should be used if required to clean trowel before applying a closing finish to the resin bound surface. Close compaction is vital to prevent stone loosening. Most applicators will compact at right angles to how the material was spread out, applying pressure as the trowel is pulled back. 
2. If required for added slip resistance, immediately cast Crushed Glass onto the top surface of the wet resin and aggregate, at the rate of approximately 0.1kg/m2. Ensure even coverage to prevent a patchy appearance.
3. Allow to cure and open to traffic as described in the Curing Time tables above.

Further Guidance:
1. Regularity and consistency of mixing times is essential to prevent shading within your Resin Bound System. Excessive mixing, especially of dry stone, will result in darker shading.
2. Ensure you have all bags required for your project prior to commencement, and ensure you have sufficient material by marking coverage per mix on the surface. It is imperative to not run short of material for a fully seamless finish. You will be provided with a mix instructions sheet with each order.
3. Ensure you have scheduled to apply your resin bound aggregate system during a period of suitable weather for both application and curing time.
4. Contact Vuba for further advice regarding our Wonders of the World Resin Bound Aggregates, if you have any hesitations or doubts.
