<\/figure>\n<\/div>\n\n\nWe have provided a free guide with tips and good advice on how to clean your block paving with a pressure washer.<\/strong><\/p>\n\n\n\n We have also included plenty of best practices that professional cleaning contractors use. They are worth reading before you begin to clean your block paving driveway or patio.<\/p>\n\n\n\n\n\n\n\n Why should you try to avoid deep-down joint sand loss?<\/strong><\/p>\n\n\n The jointing sand gives the paving bricks their locking together strength. The sand will be lost by being ‘blown out’ by the strength of the jet of water if used to clean your paving at close range. This is often the case when using a pressure washer to remove weeds and moss. “But I will replace the joint sand later”<\/strong> I hear you say. Well if you remember when you’re paving was laid, the contractor would have used a whacker plate compactor. He used this to not only compact the paving but to also force the kiln dried sand into the joints of the paving. This action locks the individual brick pavers together. You can replace this dry sand yes, but you don’t compact your paving again after each clean to lock the block paving together again.<\/p>\n\n\n\n Eventually the individual bricks will become loose<\/strong> because the sand replaced is weak and light because of non compaction of the paving around it. This leaves your paving prone to sinking because of a loss of the sand that gives strength to the structure of the paving. Especially if not replaced in the joints between the bricks. It also allows rain water to penetrate the paving joints easier which in turn leads to the sub base becoming soft.<\/p>\n\n\n\n If possible, try not to become addicted to cleaning your block paving with a pressure washer. Try using a paving cleaner or weed killer first to kill weeds and remove ingrained dirt. Pressure washing block paving should be used to gently clean and rinse the surface<\/strong>. It should not used to blast the paving clean at maximum power & force.<\/p>\n\n\n\n The lance of the pressure washer should be held at an angle so not to be removing more than the top 1-2 centimeter of the jointing sand. Remove as little sand as possible between the pavers when the cleaning takes place.<\/p>\n\n\n\n Hold the lance at a distance of around 200mm (8 inch) from the block paving surface. If possible when pressure washing block paving use the lance at an angle of 45 degrees to the paving surface.<\/p>\n\n\n\n When you are pressure washing block paving never aim the jet of water directly at or into the paving joints from overhead<\/strong>. This can do severe damage to the underlying grit sand base the block paving is laid upon.<\/p>\n\n\n\n When is the best time to clean block paving with a pressure washer?<\/strong><\/p>\n\n\n\n Pressure washing block paving can be done at any time of year. But our recommended times of year would be autumn and spring for pressure washing block paving. This is because its always good to have clean pavers before winter sets in to avoid slippy paving and spring cleaning is great before things begin to grow. After cleaning with a pressure washer consider applying an apply and leave cleaner<\/a><\/strong>. These help keep your block paving weed, algae and moss free for longer. Which cuts down on the need to use a pressure washer to clean your block paving.<\/p>\n\n\n\n Can you clean block paving with a sealer applied to the surface?<\/em><\/strong><\/p>\n\n\n\n Yes. If your block paving has been sealed with a sealant you should be perfectly fine to clean block paving with a jet washer. If a sealer has been applied by sprayer<\/a><\/strong> or roller & tray, you should only have to wash the paving using the jet washer to rinse the paving rather than to blast the surface. Always check with the sealer manufacturer if you are unsure. You may need to re-apply any paving sealer<\/a><\/strong> after pressure washing block paving. Especially if an acrylic sealer has been used to seal the paving.<\/p>\n\n\n\n Will pressure washing block paving cause white staining on the surface?<\/strong><\/em><\/p>\n\n\n\n The white blooming or staining on the surface of block paving is caused by salts being released by the paving. This is often referred to as efflorescence. If your paving is newly laid, cleaning with a pressure washer could release salts from within the pavers so this could be possible. Salts will often be released way before its time to clean new block paving with a power washer. If your paving is old or has been laid for some considerable time then cleaning with a pressure washer will not cause white staining or efflorescence to develop.<\/p>\n\n\n\nRelated Posts<\/strong><\/h3>\n\n\n\n
