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.

Hi, do you sell ‘sealer repair fluid’ or similar ? My imprinted driveway is coated with your heavy duty sealer and is showing some white patches.
We do, but we just don’t give it a fancy name like other companies, it is just the solvent.
Could you send some pictures over as it is not alway blooming that causes the white patches and there is no point spending money on something that might not work.

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.
eXtreme, our water-based acrylic/PU hybrid Sealer has been designed with a unique formula allowing it to be applied onto damp surfaces.
Modern water based hybrids are very hard wearing and Eco friendly – safe, non hazardous, low odour, etc..
It’s all in the formula and with clever blending of a range of resins combined with years of practical experience we have developed a product that performs exceptionally well specifically for use on damp surfaces.
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.
Delivery is usually 2-5 days
As long as the temperature is over 5 degrees and the day is dry then paving can be sealed all year round but the easiest times are spring, summer and autumn
Moisture has some how been introducd to the sealer, all you need to do is apply some solvent over the affected area on a dry day and the clouding will disappear
Full details of preparation are available from the download section of this website. In brief, it is necessary to thoroughly clean the paving you will be coating, preferably with a jet washer and ensure that all grease, loose materials, oil stains etc are removed.
The paving should then be allowed to dry thoroughly (full depth, not just the surface). If you are sealing block paving you will then need to apply sand to the joints and we would recommend that you do this on the day that you intend to seal to avoid the sand getting damp in the interim.
Any loose sand should be carefully brushed off the surface before sealing.
This is a common question but one based upon historical inaccuracies – the explanation is quite complex but here goes
This is a solid and requires a solvent to dissolve it – this allows the resin to be spread over the surface and once the solvent has evaporated the resin dries to a solid coating to protect the surface. The most common resins used on paving, in order of popularity, are
So what is oil based?
The solvent in which the resin is dissolved can either be an oil based derivative (such as xylene) or can be water based – and both Acrylics and Polyurethanes can now be oil or water based, and we supply all of these options.
But years ago the common description for a polyurethane was oil based
50 years and more ago polyurethanes using an oil-based solvent were popular because they were hard wearing – and, in truth, there was little in the way of alternatives for outdoor use.
During the housing boom of the ‘60s paint manufacturers developed a water-based acrylic paint for speedy application and quick drying which, to compound the problem, was applied to the poorly seasoned timber used during this boom period – resulting in very poor performance
and that is how acrylics got a bad reputation
Modern Acrylic resins (of which there are hundreds) can be as hard as polyurethanes and are now vastly improved and available either as oil based or water-based products both with excellent performance
The term oil based has now generally been dropped and it is now common practice to describe oil-based sealers as solvent based as opposed to water-based and both are regularly used by trade professionals and specified by Architects
Water-based is virtually smell free and only has a slight colour enhancing effect whereas solvent based does have a solvent smell but imparts an improved sheen and colour enhancing effect on your block paving, concrete or stone surface
The trade professionals tend to prefer solvent based whereas professional architects, who are very eco-friendly, tend to choose water-based.
Acrylics and polyurethanes used on driveways are both similar in strength and longevity but the drawback with polyurethane is that you cannot ‘touch up’ areas that are starting to wear as it will not bond to itself so has to be stripped off before refurbishment can take place.
On the other hand acrylics are capable of cross-linking which means that a further coats applied on top of the original coat will bond to the first code and simply add thickness.
With the long-term in mind the vast majority of driveways and now sealed with acrylic
The most popular sealer for driveways (by a huge margin) are solvent based acrylics such as our Block Paving & Imprinted Concrete Sealer
