Block Paving Sealing
The many millions of square metres of block paving laid throughout the UK over the last 20 years has been extraordinary. When first laid and often for the first year or so it looks superb but the climatic conditions we experience are perfect breeding grounds for moss, algae and lichen growth to soon take hold on that very expensive block paved area. Combined with weed infestation and an accumulation of dirt and oil dropped from motor vehicles etc.
Cleanpave are getting many calls from customers looking to fully clean and restore the investment they have made. The sealants we use for block paving are of the highest quality and will help to protect against weed growth and oil staining as well as enhancing and adding depth of colour to the blocks.
We will also treat and remove as best we can residual oil staining before recommending an application of sealant that in the majority of cases will fully mask any remaining oil stains.
An outline of our method of block paving cleaning and sealing is as follows :-
- A pre-treatment of weed killer or fungicidal wash is recommended approximately 1 week before we clean the block paved area. Any oil staining would also be treated at this time.
- We would then use our high powered rotary headed jet washer to clear the surface of weeds, moss, algae, dirt and general staining that may have accumulated over time.
- When fully dry, approximately 3-5 days is normal, we sweep pure kiln dried sand into the joints of the block paving to stop any lateral movement. Care is taken to make sure no sand remains on the surface and is packed tightly between each paver.
- Using professional quality spray units we would apply two coats of Smartseal acrylic sealant ,the first coat much heavier than the second, to ensure the kiln dried sand is saturated and subsequently hardens fully to inhibit weed growth and limit any block movement.
