Cleaning pavers should not be put off. The surfaces of the pavers are porous and quickly absorb oil; the longer the oil remains the deeper it sets making the stain permanent. Get oil removers from a local hardware store but make sure it is not acidic. Acidic chemicals can react with the salt of the pavers and damage it. Weeds growing in the pavers are a nuisance especially when they force cracks through the tiles themselves! Sealing pavers mostly avoid this but sometimes if the weeds are not plucked for a long time they can be dislodged from their slots. Apply a weed-killer to get good results. If the pavers are not matt finish applying a stone polish can prevent weeds from growing profusely along with providing protection. If you really want some greenery in between your pavers scatter short rooting grass or herb seeds evenly along the joints.
Inspect the joints of the pavers for sand loss. If the sand is more than ¼ inch below the joint surface youll have to "re-sand" the pavers. To re-sand you must use paver sand. You can buy this in bags at Lowes and Home Depot or at a brick yard. Spread the sand our on the pavers and using a push broom sweep the sand back and forth at a 45 degree angle from the joint lines until the level is 1/4th to 1/8th of an inch to the top of the joint surface. After the pavers have been adjusted cleaned and re-sanded (and every time after re-sanding) you want to seal your pavers with a good quality sealer. Sealing your pavers will protect the pavers from most kind staining and it will harden the joint sand locking your pavers into place and preventing anthills and weeds from growing between pavers. A good quality sealer will prevent a haze from forming on the paver surface caused from moisture in the paver when sealing. If you currently see a haze on the surface of your pavers from previous sealing youll have to strip the existing sealer before applying new sealer.
Paver manufacturers are in business to produce as many pavers as quickly and as efficiently as they can. When they have to shut the system down to change out shape molds and adjust machinery to accommodate thin paver thickness they lose a lot of valuable production time. It can take hours to switch from one mold to the next. Additionally since thin pavers arent ordered as often the order quantities are frequently less and the manufacturer is forced to produce less pavers per mold and color. This inefficiency causes increased costs for the producers and they pass those costs on to their customers. So even though thin pavers use fewer raw materials to be produced they take up more time and time is money.
After fixing any sagging areas look for individual pavers that are sitting higher or lower than the surrounding pavers. A paver that sits higher can often be leveled by using a rubber mallet to force it into its proper position. If its too high or doesnt move you may have to remove it so you can remove some of the sand thats below the paver. If it sits low youll have to remove it to add sand until its level. To remove the paver you can purchase a paver removal tool or you can use a small pry bar to loosen the paver and lift it out of its space being careful not to crack or chip the paver. Its a good idea to pressure wash the surface on a yearly basis. Pressure Washing cleans the surface of your pavers and also remove much of the organic material growing between the pavers. Removing the organic material reduces the amount of bugs living in your paver area and helps keep the pavers stable.
