Resin Bound Gravel Maintenance and Aftercare
(important to ensure resin manufacturer’s warranty applies)
It important to keep Resin Bound Gravel clean to avoid soil build up in the porous surface having a deleterious effect of the aesthetic quality of this product. The frequency for washing the resin will depend on the environment it is laid in...2 times per annum should be adequate for most situations. The resin be cleaned using a portable pressure washer up to 150 bar pressure rating. (not hot water) The pressure washer fan jet should be held no closer than 200mm from the resin bound surface. Detergent may be used in the sprayer as per the manufacturer’s recommendations. Alternatively the resin surface can be cleaned using a soft / medium bristle brush and warm water (not hot) containing a detergent such as hand wash dish liquid or similar. This should be brushed into the gravel surface and rinsed of with clean cold water. (not hot water) After washing flush the resin well with cold water.
Bleach may be used to remove soiling. Where bleach is applied to the resin surface it should be well rinsed with clean water to avoid discolouring of the surface.
Household detergent or degreaser can be used to remove oil, petrol or diesel spillages or leaks. Use these products in accordance with the manufacturer’s guidelines. Remove fuel spillages from the resin bound gravel promptly to prevent them damaging the resin.
Regularly sweep the surface of the gravel with a medium/stiff brush or broom. Mechanical sweepers with metal bristles should not be used on resin bound gravel.
Use a leaf blower or sweep the resin surface in the autumn to prevent tannin from decaying leaves staining the resin surface.
Algal growth can be removed using diluted colourless bleach. If necessary proprietary moss or weed treatments should be used in accordance with the manufacturers’ guidelines. After treating the surface remove the bleach by rinsing thoroughly with cold water. Moss growth can be removed by using a pathway moss remover. (do not use a moss remover which contains iron sulphate as this will stain the resin surface) Domestic weed killer products can be used on the resin. (do not use oil based weed killers)
Chewing gum can be removed using a freeze spray such as Prochem chewing gum remover. (www.prochem-uk.com) After the gum is frozen, scrape off using a wallpaper scraper or blunt knife. Alternatively freeze the gum using ice cubes in a polythene bag before scraping the gum off the surface.
In frosty conditions salt can be applied to the resin surface if necessary. Wash salt from surface when frost goes. (solvent based de-icing agents should not be used)
Snow should be cleared using a plastic bladed shovel. Metal spades or shovels should not be used.
Solvents can damage the binding properties of the resin. If a spillage happens wash the surface immediately and rinse thoroughly with plenty of water.
Do not drag heavy sharp edged objects over the resin surface. If there is a risk of heavy point impacts due to work or other activities, place a protective cover over the resin bound gravel until the relevant activity is completed. If pallet trucks are being pulled over the surface place a protective cover over the resin first. Car jack and scaffold poles should have timber supports below them to prevent point impact damage.
The resin surface should not be exposed to objects such as burning candles or other extreme heat sources. Extinguishing cigarettes on the bound surface will damage the polyurethane resin.
Some of the stones in the various mixes contain ferrous oxide which can cause some rust staining. If this is an issue ensure staining can be removed using oxalic acid. When removed the stone from which the staining derived should be resealed.
