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.

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.

I’ve sealed my customers sandstone with resiblock superior gloss and wondered if you could advise if easy strip 2000 will remove it? And won’t damage the paving? And what is the application process.

Yes the Easystrip 2000 will remove the sealer without damaging the stone, you can find the full application instructions on the product page under the Tech Data tab.

I have a paved patio which has stone or concrete slabs and in need of protection from stains and general annual growth. Can you advise what is the best product in your range to use?

If you are uncertain whether the flags are stone or concrete I would recommend using our Stone and Slate Protector (link below), this will be ok to use on either surface.

Advice on stain colours

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.

Will this work on block paving.

Yes they will, they are ok to use on any concrete based product, just bear in mind that the coverage will be severely reduced, by at least half.

Yes we do have a stripping solution that will work with the Resiblock sealers (link below), this is an eco friendly water based stripper so is very safe to use and won’t damage the paving.

Colours with Concrete Advantages

WHEN IT COMES TO COLOURING CONCRETE SURFACES LIKE PATIOS AND DRIVEWAYS, NOT ALL PRODUCTS ARE CREATED EQUAL. MICHAEL PALIN, MANAGING DIRECTOR AT ADSEAL, EXPLAINS MORE.

Adseal BMN 2

With summer now upon us, many homeowners are looking at their driveways, patios and other paved areas with a view to realising improvements.

For some, it might be case of breathing new life into an old concrete surface where time, traffic and the good old British weather may have taken their toll.

For others, it could be a desire to realise something more creative such as a picture, a pattern or another design feature, possibly inspired by the numerous interior design and gardening programmes now on TV.

Whatever the motivation, there are different ways of achieving the same goal.

Paint. Best known but is it best suited?

Paint is a widely used solution for colouring or recolouring concrete surfaces in the UK. But just because it’s a common choice doesn’t necessarily mean it’s the best choice.

Certainly paint has its attractions. It’s cost-effective for a start both in terms of product pricing and the labour costs needed to install it.

In fact, paints tend to be fairly low odour and fairly low in their use of hazardous chemicals meaning they can be applied by the untrained user.

Paint also comes in an enormous range of colours and those colours are usually predictable. Putting that another way, the colour you see in the tin is the colour you’ll end up with on your driveway, patio or paved area.

Paint does have its drawbacks however. These stem largely from the fact that paint doesn’t permeate the substrate it’s being applied to. Instead it adheres to its surface.

As a result, paint can be prone to cracking, peeling and flaking. It can also fade over time.

Plus, while paint can be used for some detailing type applications, there are other alternatives out there better suited to the task.

Taking the Acid Test

Posted in Block Paving, Colouring, Concrete, Driveway, Patio, Paving   

Paint may be the default choice for many looking to colour or recolour concrete but acid etching using chemical stains offers another, less well-known alternative.

Adseal BMN 5

Most stains used in acid etching are a mix of water, hydrochloric acid and acid-soluble metallic salts. They work by chemically reacting with the concrete.

First, the acid etches the surface allowing the metallic salts to penetrate more deeply. The stain then reacts and the resultant colour becomes a permanent, sub-surface part of the concrete.

As a result, acid based chemical stains offer some key advantages over paint such as the fact that they won’t crack, chip, peel or fade.

As for the drawbacks? Well, these stains come in a fairly limited colour palette typically restricted to earthy tones such as tans, browns and terra cottas.

The colours are also unpredictable. The colour you see in the tin can be different to the colour you end up with because the staining relies on chemical reactions. Colours can also be blotchy in their intensity.

Bigger issues stem from the use of hydrochloric acid. Acid based stains must be applied by trained professionals familiar with COSHH working practices. As such, while product costs for acid based stains are comparable to those of paint, labour costs are invariably higher.

Acid based chemical stains also give off unpleasant odours which can linger and they are messy.

After their application, the treated surface must be neutralized with a mild alkaline detergent. After that, the surface must be washed with liberal amounts of clean water.

Acid based chemical stains are also unsuitable for detailed work as the colour tends to weep into surrounding areas.

Water Based Stains. A New Choice – A Better Choice?

A third and lesser-known way to colour or recolour concrete is to use water based stains.

Adseal BMN 4

Water based stains cost a little more than paint or acid based chemical stains but their benefits are arguably worth it. They also offer some of the lowest installation costs of all.

Like an acid based stain, water based stains permeate the concrete to leave a permanent colour that won’t chip, flake or fade. Unlike acid based chemical stains however they do not contain any hazardous chemicals making them better for the environment as well as safe to use by unskilled labour.

Water based stains also give off virtually zero odour and are completely predictable. The colour you see in the tin is the colour you’ll end up with. The colour choices are almost infinite too. You can even mix colours to achieve a very specific shade or hue.

Water based stains can also be used to create all manner of effects, such as the veins of marble or the aged and weathered appearance of slates or tiles. In addition they can be used to replicate acid etching or on previously acid etched surfaces to completely eliminate any blotches.

Finally, water based stains were originally developed with detailing work in mind. As a result, they can be used to create intricate patterns and designs like logos, house names and house numbers with the help of a stencil.

Water based stains may be a new choice on the UK market but to Adseal – a business with over 45 years of surface protection and concrete colouring experience – they are a better choice. That’s why we have developed one of the biggest ranges in the UK.

Once the trade professional or homeowner has experienced the benefits of water based stains for themselves, we’re confident they’ll be equally converted.
