Advice on repeat use of sealant on my paving - Paving sealant

[elviseatspizza]

Hi
Three years back I used the website for advice on using a sealant on my paving at home.

I used Resiblock K-Seal on my block paving. The results were very good - clean look,no weeds at all since then and minimum maintenance.
I did wish it provided more colour and I may have been happier with a wet look.

Now after 3 years I can see that rain water is not sitting as droplets on the paving any more and the edges have shown the first evidence of little grass/weeds.

When would you suggest I top-up the sealant? Do I need to stick to all the rules before using the sealant as before (7 days of sun,etc!) or can I just use a good wash, top up the sand and paint the paving over? Will I need less amount than before? Any other advice?

Lastly do you think I could use a different sealant to get a wet look or can I not mix two different types? Any chance of using a colour enhancer or is it useless on a paving already sealed?

Thanks.

before you can use a colour enhancer id imagine the old sealant would need to be removed first then applied then re sealed

roger form r & a pressure washing will know more and I'm sure will answer as soon as he sees the post

Don't use a different sealer, (have to admit I don't know Resiblock's K-Seal?) new one to me. Using two different types of sealer is when the problems start, but Craig from Resiblock also comes on here so he will point you in the right direction with his products. IMO stick with same product, but if you really want the "wet look" then maybe Resiblock Superior might work, but as I said wait until Craig has seen this thread and he will advise.

K-Seal is an acrylic based product sold by Kingfisher and has nothing to do with our company. Resiblock products are in the main based on polyurethane technology. You would need to establish which product was actually used as re-sealing an acrylic is significantly different to over-coating a polyurethane.

Should this information not be available to you; find an area which has not been UV degraded (typically under a plant pot) and leave a rag soaked in a Xylene based solvent on the glossy area. If the sealer softens it is K-Seal, if it is unaffected it is a Resiblock product.
