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.

I have a concrete kitchen table and am looking for a sealer to give it some protection from stains and heat. What is the best product you have that you could recommend that I use.

For the best protection, I would recommend using the High Gloss PU sealer, this will offer the best protection against stains and spills, it is fairly heat resistant but I wouldn’t recommend placing pans directly from the hob on to the sealer.

I am looking for the correct colour concrete stain, do you have sample sizes?

I’m looking to enhance an area of concrete and was wondering if you might be able to do smaller ‘tester’ samples at all? At the moment the concrete has just been laid and is it’s natural colour. We think we’d like it to be more of a slate / charcoal sort of colour but not sure, so we’d like to trial a couple of tiny areas first.

We also like the idea of stencilling, and considering a grey finish with lighter grey / white-ish pattern.

What product(s) would you recommend, and can you do little samples?

Kind regards,


Firstly as the concrete has just been laid you will need to wait a minimum of 30 days to allow the concrete to cure before applying the stains to the surface.

You will then need to acid wash the surface to remove any dust or dirt and to profile the concrete to allow the stain to penetrate properly.

I would then suggest using the Solid Colour Stain to the surface, this will give you an opaque colour in whichever colour you choose.

Then if you are looking to use any further colours you will need to use the Smartcolour stain over the Solid colour.

Both these colours are available to by in a 4oz tester size.

Colours with Concrete Advantages

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.

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.

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.

Does my stamped/printed concrete driveway definitely require sealing?

Posted in Concrete, Driveway, Top 20 FAQs   

The simple answer is yes, it is important that stamped or printed concrete is well sealed as the colour in the concrete is only in the first few millimetres, so if the colour wears off back to the concrete it is very difficult if not impossible to get it looking right again.

The easiest way to avoid this is to make sure the seal is regularly maintained.

Are sealants manufactured for concrete driveways toxic?

Posted in Concrete, Top 20 FAQs   

Whenever you are buying sealants, check for hazard and safety warnings on the product label. Generally, there are non-toxic products available in the market.
