I will be cleaning one of these shortly, is it ok to clean them with p/washer and if so do they need sealing afterwards, thanks in advance, Dave. ???

The advice the custy should have been give on completion of insall is: Absolutly no presure washing, as it WILL strip or at best thin the resin seal exposing concrete.
The correct method of cleaning is wearm soapy water and a sweeping brush. As dirt and moss etc can't get a "grip" on the sealed surface it will come of easily.
However I clean loads prior to resealing and I do use a p/washer with surface cleaner. I lift the cleaning head as high as it wil go, then rice off afterwards. This is fine as more seal is being applied (p/washing doesn't remove all the seal) This is to remove dirt etc as the resealing lads are going to soften the left on seal with a solvent before re sealing

Thanks drivewasher, if I clean it up with soapy water using a fairly stiff brush, is it likely to remove some of the sealant at the same time, to be on the safe side do you think it would be best to give it a coating of sealant anyway.

Brush and water wont remove any resin, a pressure washer will.
Bear in mind tht the resin sel protects the surface of the concrete, so a driveway a couple of years old will already have the resin wearing off on high traffic volume area's. Like in the gateways and around doors and steps

Why do they soften the surface before re-sealing?thanks Dan

So the new seal sticks to the old then it all cures together as one laminate.
If you just put new seal on top of old it will de-laminate (peel off and/or appear salty)

i have pressure washed a few of these and just get the custy to reseal them themselves.

What do you use to soften it?How do you clean seal off that is rough in places before re-sealing,thanks Dan.
