Driveway Advice
Will a resin-bound driveway fade or change colour?
A resin-bound driveway can change appearance over time, but the resin type makes a major difference. DALTEX explains that non-UV-stable aromatic resin can darken in sunlight and may shade unevenly where cars or objects block the light. UV-stable aliphatic resin is designed to reduce that colour change. Ask the quote to name the exact resin system, confirm whether it is UV stable, and separate the product guarantee from the installer's workmanship guarantee.
UV stable and non-UV stable are different specifications
DALTEX distinguishes aliphatic UV-stable resin from aromatic non-UV-stable resin. Its guidance says aromatic resin is affected by sunlight and can darken, while aliphatic resin is used where colour stability matters. The word resin on its own does not identify which product is included in a quotation.
Uneven shading can make colour change more obvious
A regularly parked car, wheelie bin or planter can shield one part of the surface while surrounding areas receive daylight. DALTEX warns that this can create visible differences when non-UV resin is used. Ask whether the proposed colour and resin combination is suitable for the way the driveway will actually be used.
UV stable does not mean the driveway needs no care
Dirt, algae, tyre marks, leaf staining and wear can change how a surface looks even when the resin itself is colour stable. Cleaning should follow the installed system's aftercare instructions. An appearance concern should be diagnosed before anyone assumes that the resin has faded.
The exact system and batch control matter
A written specification should name the resin manufacturer and product, aggregate blend, colour, mix design and intended depth. Consistent materials and mixing help reduce avoidable variation. If an installer changes products or aggregate batches, that change should be agreed rather than hidden inside a generic description such as premium resin.
Read product and workmanship cover separately
A manufacturer's product guarantee concerns the qualifying product and its stated conditions. Workmanship cover concerns preparation, mixing and installation. DALTEX's published product-quality guarantee, for example, excludes installation and has eligibility conditions. Ask for both documents before relying on a headline guarantee length.
What to put in the written specification
- The resin manufacturer, product name and whether it is UV stable.
- The aggregate blend, colour and sample approved by the homeowner.
- The mix design and installation depth for the intended use.
- The aftercare instructions for stains, algae and general cleaning.
- Separate product and workmanship guarantees with their conditions.
| Question | Why it matters | Evidence to request |
|---|---|---|
| Is the resin UV stable? | Non-UV resin can darken and shade unevenly | Exact manufacturer and product name |
| Which aggregate blend and colour? | The stone determines much of the visible finish | Named blend, sample and batch plan |
| Will cars or objects cover one area? | Uneven light exposure can reveal shading differences | Product guidance for the proposed system |
| What care is required? | Soiling can look like fading | Written aftercare instructions |
| What guarantee applies? | Product and workmanship cover different risks | Both documents with conditions and exclusions |
Frequently asked questions
- Does all resin-bound surfacing use UV-stable resin?
- No. DALTEX describes both UV-stable aliphatic resin and non-UV-stable aromatic resin. The quotation should identify which one is included.
- Why is the area under a parked car a different shade?
- An object can shield part of a non-UV-stable surface from sunlight while exposed areas darken. Dirt and moisture can also change appearance, so the cause should be assessed rather than guessed.
- Is UV-stable resin worth specifying?
- For an external decorative surface where keeping the intended aggregate colour matters, DALTEX strongly recommends UV-stable resin. Compare the exact system and written cover, not only the generic label UV stable.
- Does a long product guarantee cover installation defects?
- Not necessarily. Product guarantees normally apply to the qualifying material and their stated conditions. Preparation and installation should be covered separately by the installer's workmanship terms.
