Approx 4 to 8 sqm per litre depending of the porosity of the substrate and method of application. For a rough guide divide the area by 6 to give the number of litres required.
NEW BLOCKS - Apply as soon as possible after insallation. Remove excess sand. Apply above 4oC and ensure two hours minimum to dry. Do not apply to wet surfaces or if rain is imminent, or if efflorescence is present.
OLD BLOCKS - Fully clean off surfaces with power wash and a degreasant to suit. Allow to dry thoroughly and re-apply jointing sands/grouting material before application.
Spraying - Use a standard spray unit. Apply two coats with sufficient drying time between. Second coat at 90 degrees to first. Roller/Brush or Squeegee - Can be used for smaller areas - avoid excessive pooling and over coating.
For Best coverage spray apply at approx 3.0m2 per litre, other methods will reduce coverage to approx 2.0m2.
Ensure adequate supplies are available. Agitate drum before opening. Keep sealed when not in use. Clean spillages with thinners. Harmful by inhalation and if swallowed. Irritating to the skin. Do not use in an enclosed space without adequate ventilation.
PAVING SLABS - Allow paving to weather in for at least 6 weeks before applying a sealant. The paving should be clean, dry, free from dust, detritus and organic material (weeds, mosses, algae, etc). Generally speaking, if there are to be any serious problems with new paving, they'll become apparent during those first few weeks.
Country of Manufacture
Our standard method of delivery for heavy items is using the pallet delivery network. The delivery will arrive on a lorry with an electric tailift and a hand pump truck.
Access must be made for a lorry (up to 32ft) otherwise additional delivery charges may be payable. You must advise us of any restrictions that will impede the delivery vehicles from delivering the Products. The Products will be delivered to the kerbside outside. Our couriers are not insured to take goods onto your premises without permission. If you require the driver to come onto your property (at their discretion and deemed safe) with the wagon, the Products, or both, this is entirely at your own risk and if the driver or wagon damages anything (including but not limited to, manhole covers, tarmac driveways, block paved drives, flagged driveways / graveled or stoned driveways, grassed areas, walls, pillars, gate posts, gates, trees, hedges, telephone wires, lights) the cost of repair will be your responsibility.
Ensure that the delivery area is flat and solid enough to take the weight of a pallet truck carrying up to 1000kg in weight. Please note Gravel and Grass are not classed as solid and flat. If the delivery area is not flat the driver will require help in getting the pallets off the vehicle. If help cannot be given there will be a redelivery charge to deliver at a time when help can be given. If you live on a hill you will need to call us before you order to find out if our delivery company can deliver to your address. This is for health and safety reasons, usually the easiest method of getting around this is for the order to be delivered to the nearest flat ground. It will be your responsibility to move the goods to your property. Deliveries via hiab or moffet can be arranged but at an additional cost, click for further details.
Smaller items will be delivered via a parcel courier.
All delivery methods will require someone to accept the delivery, check it over and sign that they have been received in good condition. Please note any damages on the delivery sheet / electronic device, do not use the product and contact us straight away.
Next day, AM/PM or even Saturday deliveries can be arranged at an extra cost. Please add your items to the shopping cart for an instant quote.
After your order has been dispatched you will be contacted on the phone (within 2 days), by your local pallet delivery company in your area, once they receive the goods from our local depot, to book-in a day that is convenient for you. (this will not occur on Timed, Next Day & Saturday deliveries)

Remember when handling your goods:
Take care when removing the packaging / banding and also when removing the product out of the crate / pallet as they may have weakened during transit and could be unstable.
The product is quite heavy, and some larger products can weigh a lot. Consider this when arranging the delivery, as you may need appropriate lifting equipment, or an extra pair of hands.
