The Inspection happened yesterday (Tuesday).
The Inspection has recommended for the Paving to be Sand Blasted.
The Paving Slab I treated with LTP Solvex, when wet looks good with no water beading, but when Dry looks really Poor, many shades of Grey.
The remainder of the Paving when Wet is Water beading like crazy.
Some of this water beading still has oil residue in it.
Also the paving seems to be getting stickier under foot.
The owner of the Sealant Product has said from the Pictures he's looked at, he can see dust marks alongside some of the Tarp marks too. He's asked if the instructions were followed in regards to Jet Washing before sealing, I've confirmed it wasn't. Hence the Dust marks.
The instructions which I'm trying to get a copy of & verify, may also state the Tarp should have a 1 meter air gap if the paving needs to be covered due to weather whilst drying. Also not to use the sealant in Inclement weather or chance of Rain.
The cost of the Sand Blasting is £200, which the Builder has said he'll put a little towards as it's 'not his fault', apparently it's an 'Act of God'.
Have asked the Vatican Help Desk how I charge the rest of the Sand Blasting cost to God himself, but don't seem to making much progress.
Sorry to add no date agreed yet on Sand Blasting, still weighing up all the options, so any further feedback would be appreciated.
sand blasting may change the face of the flags
personally I wouldnt go that way
you have had some decent advice here,but cavaet emptor if you go for sand blasting
LLL
As I said earlier I wouldn't go the sand-blast, messy and which as also been said will change the face of the paving, which will then need more work doing to them so an added cost.
Either the rotary option or if you really want or need go the "blasting" option there is another system that will do this without the sand element, high heat very low pressure less damage to the paving but would be more expensive to use.
If you do go the sand blasting route which is sounding a cheap cop out option be prepared for the extra expense of getting the surface correct to seal again.
Whoever has reccomended sand blasting is talking nonsence. They have clearly got no idea what they are talking about. Like rog says its a cheap fix which will not give you the desired look. I will be hearing back from my drytreat rep tommorow so I will let you know what he said
