I have a large drive that I jet wash each year however each year the drive needs to be re-done as the blocks are becoming more discoloured and have moss around them. can you recommend a sealant I should apply to improve the finish of the drive, reduce the discolouring and keep the moss at bay?

Most people don’t realise that jet washing paving regular is very bad for the surface, jet washing accelerates wear effectively reducing the lift span of the paving, as well as this is makes the surface rougher which is better for moss and algae, allowing them to get a better hold on the surface and finally, jet washing when the sand isn’t sealed can remove too much sand and over time will start to affect the sub base which can cause the block to become unseated and become unstable.

I always recommend the people seal their paving as it helps to reduce the moss and algae build up and protects the surface which means it will last much longer before it needs to be replaced.

The sealer I always use and recommend for block paving is our Block paving and imprinted concrete SP sealer (link below), this sealer will give you the best protection and give the best finish.

I have a terrace of indian sandstone which has developed terrible black spot lichen everywhere. I have pressure hosed off as much as possible but cant get it all off. If I could keep it like it is that would be ok even tho some spots remain.
Would your Stone and Slate Protector prevent the regrowth of the lichens and algae.

Yes applying sealer to the surface will stop the algae and lichen from being able to take hold on the paving (it may form on the surface but it will be easy to wash off/treat), if the algae does come back (if there are a lot of trees in you area) it can be treated with our moss and algae remover which you just spray on to the paving and leave to do its thing.

Will the Sealer stop weeds, moss and algal growth?

Posted in External Sealants, Moss and Algae   

Weed seeds and moss algal spores can still fall onto your paving and germinate, but the surface is unattractive for them as it is not longer damp and porous, and so they are less likely to germinate.

Equally, should they germinate there is less likelihood of their roots or filaments to be able to get a foothold on the sealed paving. In any event, weeds moss and algae should now be easy to rinse or brush off.
