Staining a new driveway

Posted in Driveway, External Sealants, FAQ, Paving, Sealants

Mrs Vanessa J Warren

We have just had a driveway done and the flags are too light in colour (I like them when they are wet!) Looking to darken them up in a grey but need to know exact colour and maybe try them out first (I have spare flags to test on)

If the flags look ok when they are wet then all you need to do is apply a sealer, this will leave the flags looking like they do when they are wet and it will protect them from stains and general wear and tear.

I have linked a couple of products below (you didn’t say if they were concrete or natural stone flags) the first one is for concrete surfaces and the second is for stone.

Best sealant for Indian Stone?

Posted in External Sealants, FAQ, Paving, Sealants, Solvents, Stone, water based   

This question was asked by
Alan Buxton

which sealant is best for indian Stone solvent based or water based?

It all depends on how you want the sealed paving to look, a solvent based sealer will enhance the colours and leave the paving looking like it does when it is damp, whereas the water based sealer will leave the paving looking more like it does when the paving is dry.

Sealing Porcelain tiles

Hi, I’m looking at buying some of the gloss finish sealer from you. Can you advise me on a few things please. 1, can this be applied to External Porcelain tiles? 2, what’s the best way to apply this? & 3, what’s the coverage of the a 5 liter tin? Questions 2 & 3 are probably on you site somewhere but if it’s not in big letters I’ll never find it! Apologies.

Thanks for your help.

If you are wanting a gloss finish on external tiles I would recommend using out High gloss PU (link below), Porcelain can be tricky to get sealers to adhere to, especially if they are glazed which is why I suggest the PU as this has very good adhesion properties.

Preparation and sealing of block pave drive

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.

Indian Stone Sealer

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.

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

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.

Advice on stain colours

Jon-Luke Kirton

We have a a large driveway (approx 200m2) with standard red block pavers. We would like to change the colour of these to a slate grey colour (we have a period character sandstone and traditional scottish slate house). What products would you recommend for this look to be achieved?

To completely change the colour of the paving is entirely doable, I have linked below the products you would need and if you check out the videos section you will find how to guides for the prep and the application.

Firstly you would need to remove any sealer that might be on the surface using either the Solstrip or Easystrip 1000 for acrylic sealers or the Easystrip 2000 if it is a Polyurethane sealer.

Once this is done you will need to profile the surface to make it porous to accept the stain then you would apply the Solid colour stain as a base colour, then a diluted Smartcolour to give the 2 tone antiqued effect.

After the stain has cured for 24 hours you will need to re apply a sealer coat.

This question was asked by
Mr Peter Critchley

Can you advise on when to use your AdSeal Stone and Slate Sealer on my newly as in two weeks old Indian stone patio . Some say leave till summer others say wait for a dry day ??

To apply the sealer you need the stone to be dry and the temperature to be above 5 degrees.

You will also want the weather to stay dry for a minimum of 2 hours after you finish applying the sealer.

Concrete waterproofer

Andrew Morris

We have cast a garage base 2 weeks ago alas labourer forgot admixture so looking for a penetrating concrete sealer as a waterproofer from rising damp, therefore can you recommend any of your sealers to fill the voids ?

Pretty much any of the sealers will help to stop damp, I have put links to 2 different products, the first is our most popular solvent based sealer for concrete surfaces, the second is a water based based option (no harmful chemicals or strong smell).

Either will be fine to use.
