Hi I have a resin surface driveway. The stones are coming loose more often. Could you tell me what sealer I would need and the best application kind regards Graham
The only sealers I ever recommend using on Resin bound stone are our water based sealers (linked below).
Solvent based sealers, if over applied can cause the resin bound stone to lift and ultimately break up, using the water based you will never have this issue, regardless of how much you apply.
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.
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.
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.
A common misconception is that you have to wait 3-9 months to seal paving, this is not the case at all, as long as there is no efflorescence (white chalky deposits on the surface) then the paving can be sealed as soon as it has been laid.
As with a lot of things this is a bit like asking, how long is a piece of string.
There are many factors that determine how frequently the paving will need recoating, the biggest of these is how frequently the paving is driven/walked on.
The absolute shortest period the paving should need recoating is 12 – 18 months, this is with very heavy usage ie. a fully loaded van driving across it two or three times a day, but the chances are that it will last much longer.
This all depends on how porous the paving is, but as a general rule of thumb for applying 2 coats a 25ltr drum will cover apprix: block paving 50m per drum: pattern imprint 70m2: flags/slabs 70m2 and tarmac 65m2. These are approximate guidelines only and actual figures may vary.
Yes for standard use ie. cars vans etc.. the required thickens is fine, if however it is in a commercial area, then you can increase the thickness but this will reduce the coverage rates of the packs.
Delivery is usually 2-5 days
When you buy a new carpet you probably have it stain guarded and certainly you will wax your car, you do this to protect their surface and make them last longer. The same applies to paving and flooring, whether it is outside – block paving, pattern imprinted concrete, stone or flags, or inside – stone, slate, travertine, etc., – they all need care to look better and last longer. Applying the sealer will protect the surface, reduce maintenance, and help it last longer. In addition, it will also stop oil and grease stains and help resist the growth of weeds, moss and algae. It is particularly important to use a sealer on block paving as it acts as a structural stabiliser. The sand is a structural part of block paving spreading the load by friction from one block to the next. It is important to keep the sand in position and stop it being eroded by wind and rain water. The protective properties of the sealer will not only lengthen the life of your paving (as it reduces physical wear), but will also keep it looking like new as the inbuilt UV filter will help retain its natural colour.
