How to Repair Chipped Pebble Paving
Pebble paving is very common these days. You must have seen this across many swimming pools, entries and decks of finest, hotels, resorts and offices. These pavements are laid with a mixture of small pebbles using an epoxy adhesive to make gorgeous and sturdy nonskid surfacing. Recently, many people have started creating this type of pavements. This involves an easy process and most of the homeowners can follow it themselves. The pebbles used for this type of paving are very small in size in the range of 1/8 to 3/8 inches. Smaller size pebbles provide favorable results as compared to larger pebbles. The 2 components of epoxy adhesive comprising a resin and hardener are mixed for adhesion. The adhesive mix is then mixed with the natural quartz stones and laid over the existing concrete surface. It creates amazing epoxy stone flooring, which is very attractive and durable. The surfacing is a thin layer. It may wear out or chip off with time and need repairs.
