Preparation and sealing of block pave drive

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.

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.

I’ve just had a new block paved drive laid and I’m wanting to seal it. It’s 130sq.m. and it will have 2 cars and a caravan on it on a regular basis. I’m wanting to proof it from oil leaks and stains but also enhance the colour to a sort of a ‘wet look’ without making it look too glossy. What do you recommend?

I would recommend using the Block paving SP sealer this will do what you are looking for, I would suggest getting 2 x 25 ltrs and 1 x 20 ltrs to complete the job.

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.

This question was asked by
Jon corke

i sealed my block paved drive about 6 weeks or so ago i used resiblock matt superior this is a solvent based sealant, but it has dried awful leaving big black circles an dirt marks, made the drive look awful, do you guys sell a sealer remover for that kind of sealer? If you do will it damage the block paving? We have barleystone castlepave smooth blocks in birch colour, thanks in advance

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.

Pets

This question was asked by
Pam Hayes

I will need to buy the Concrete and Block Paving Sealer SP, and also the Stone and Slate sealer. As these contain solvents etc. are these dangerous to pets?

They can only cause an issue whilst drying, once it is dry its fine, usually not much more than 2 hours (depending on the weather).
But unless they walk over it as you are actually applying the seal it will only cause a little bit of irritation to the pads, nothing that would require treatment.

If you are worried about a shower arriving later in the day, then try Adseal SP a  solvent based sealer designed to be less susceptible to rain spotting than other sealers.

Again it’s all in the formula plus years of practical experience, enabled us to develop a product that provides outstanding performance and has an exceptional ability to cope with rain spotting – we have many anecdotal reports of rain showers arriving either shortly after or just before sealing is finished and there being literally no sign of rain spotting – and if there is it’s simple to remove it.

What if it rains unexpectedly during sealing?

 

Can I apply sealer if it is forecast to rain that day?

Clearly avoid rain if you can but, because rain can catch you unawares you should be using one of these two.

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.
