Take care if you choose to do your own pattern imprinted concrete driveway reseal. When we use the term reseal, we do so with an air of caution. The term can be taken too literally when customers reseal their own pattern imprinted concrete. Disastrous consequences are seen all too often when the owner of a pattern imprinted product does not properly prepare the surface, or take into account the existing seal on the drive. We have witnessed the effects of seal being lavishly brushed on top of seal and re-applied on numerous occasions until the sealant is so thick and layered that areas begin to flake and pluck.
Like any work, time and care must be taken to prepare the surface, firstly by breaking the existing sealant down and suspending it with a xylene based thinner, thus giving the opportunity to ‘bond’ and judge the amount of sealant present on the drive. When we have judged how much sealant is present, we are then able to decipher how much seal is required to be reapplied, using the same xylene based thinner to thin down the sealant depending on the need for it.
Not only do disproportionately sealed drives pose the threat of flaking and plucking, often taking the surface of the colour hardener with it, but they can become hazardously slippery. This can also, when the driveway is sealed in the correct manner, open up a proverbial ‘can of worms’. When the xylene is applied, whether it is an attempt to work it into flaked areas or to try and breakdown existing sealant, it can cause the copious layers of seal to ‘curdle’ and rub off with ease, as seen in the accompanying video. So when sealing your pattern imprinted concrete make sure you do so in the correct way, otherwise you could be merely concealing a problem or creating a whole new one.
