Preparation and sealing of block pave drive

This question was asked by
Paul Hodgetts

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.

Internal wall Sealant

This question was asked by

I have uncovered a stone wall inside my house. The stone needs sealed to stop dust but it is also dull looking. What would be the best product of yours to use? I would prefer a gloss finish to a Matt finish. As it’s an internal wall I understand it needs to be able to breathe or damp becomes an issue. Please can you advise?

For an Internal wall I would recommend using our Water based sealer (link below), it is safe to work with when applying it to a vertical surface and it has very little odour so wont smell the house out.

Indian Stone Sealer

This question was asked by
Ian Sutcliffe

l have had a patio laid two years ago with Indian stone and didn’t realise how easily it stained. I am going to clean it this spring and would like to see if l can protect it with a sealer but not darken the colour if possible, could you please advise, approximately 85 square meters area,

As you are looking to keep the paving looking as it does when it is dry I would recommend the Water based Matt sealer (link below) this will have very little effect on the appearance but will offer a good amount of protection for the stone.

Stain or Paint my driveway ?

This question was asked by
Ron Turnbull

In April or May I want to paint or stain my driveway which looks bland.
Would take 10 – 12K to replace :-((
The house was built back in 1971 and the driveway is concrete but has a rough “tamped rough finish”.
I hear conflicting info regarding painting or staining the concrete.
Can you advise me – should I paint or stain ?
There are 2 cars sitting on the driveway.
Can you recommend a product of yours that would be best suited and how best to apply it.

I would forget about painting, the paint will start to wear off after a few months.

Staining on the other hand (as long as the prep is done correctly) soaks into the concrete to form a permanent bond.

I would suggest using the Solid colour stain (link below) as this is the quickest and easiest way to brighten up tired looking concrete.

For Prep, mixing and application please review the videos section on the site.

concrete staining

This question was asked by

I would like to acid stain a concrete floor that has been grounded with 200 grit pads and densified, will the adseals smart color dye work on the concrete?

For the Smartcolour stains to work properly the concrete need to be porous enough for the stain to soak in. Please look at the videos section on www.adsealcolours.co.uk, the last video shows you what you need to look for in regards to the prep.

Colouring and staining

This question was asked by
Sam Butler

I have recently made a concrete table for use inside. I was looking at possibly using your smart stain to make it a darker shade as it didn’t really come out as dark as I had liked. Wondered what it was like to use on new works. Also was looking at your polyeurethene gloss sealer. Was just looking for some advice really.

Yes the Smart colour will be ok to use and the High gloss PU will give a very nice gloss finish.

In regards to the prep work you will need to acid wash and profile the surface to remove any dusty material from the surface and to increase the porosity (there are a couple of videos on the website to show you what to look for when prepping the surface).

high gloss sealer for travertine

This question was asked by
Keith Askham

can I use this product effectively in a shower area

I have Travertine tiles in my own bathroom, I sealed it with the High gloss PU about 4 years ago and it still looks good as new. The only thing I will say is you need to let the sealer cure for a at least 48 hours before using the area.

Slate sealer

This question was asked by
Kevin Banks-Dunnell

I want to seal my outside slate patio with a heavy duty high gloss sealer, which product would you recommend please?

You have a couple of options (links below) the Heavy duty sealer is the cheaper of the two and is easier to use but wont last as long, whereas the High gloss PU will last longer but you have to make sure that the paving is 100% dry and that you will have at least 5-6 hours of dry weather once it has been applied.

protecting stone from lichen and algae with sealer

This question was asked by
marcus

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.

Protecting Welsh Slate Flooring

This question was asked by
Jared F

I have a welsh slate floor that was put down 5 years ago in a kitchen. It needs re-protecting as the original stuff I applied has now rubbed off and some small areas now have the bare stone showing (places where chair legs have rubbed etc).

What’s your advice for this in terms of products you suggest and the method of application?

I would suggest using the High gloss PU, this is a very hardwearing sealer, but I would suggest removing the old sealer first as it is obviously having issues with adhesion.

Application instructions will be sent with the product.
