To seal or not to seal paving

[Barry White]

Hi layed a lot of paving its concrete pressed type with a riven finish. as its only a couple of years old it still looks new and I want to keep it like that should I seal it with someting like this http://www.screwfix.com/p/no-nonsen...SSDXQJUeixahhooLm_E22_QXSLiqybw8PAaAiV-8P8HAQ
or just presure wash it every couple of years?
so what do you do with your patio and paved areas?

Only thing is where will the water go if everyone sealed them completely.
Just being the devils advocate.

just jet wash it every couple years, if the water has no where to go you will get moss or algae

but be careful with the pressure washer. too much can wash sand from under the slabs and make them wobbly.

good some paving diy done in my garden, used pavement slabs from sidewalk down the road when they got resurfaced with asphalt.
picked up a van load for free, road work guys were happy we saved them loading the lot into the skip.
i brush it with a bucket of water and a broom every now and then and thats it.

By concrete pressed type, do you mean pattern imprinted concrete? If so you obviously don't have to worry about washing sand away when pressure washing it as there isn't any. Have a look at the paving expert website/book, by Tony McCormack he knows his stuff.

i'm thinking of the 2" of sand under the slabs. different if the slabs are cemented in place.

no they are separate pavers laid on a bed of mortar



seen some done and look like they are varnished (wet look) and want mine to stay the supplied colour dry look

ring DNO. they'll come and seal it for you. :19:

Don't bother jet washing or sealing.

Every few years you can "wash" them by spraying them with red label hypochlorite, brings them back to new.

will this not kill my grass?

I don't know but i'll find out. You would only spray it on with a watering can and then scour it with a yard brush. Farmers use it to wash out dairy parlours. We use it around our house (but we have kerbs) instead of power washing because it washes out the sand from flags and pavers etc

 

[rapparee]

Yes it can kill the grass.

But if you put in on with a weed sprayer on a dry day and just put enough on to wet the patio and let it dry in then it wont damage the grass. It will eat away at the moss over a day or so and clean up the path with no damage. Don't be having the place like a river.
