The Best Filler for Long-lasting Masonry Repairs

By Mike Gregory


I’ve been a decorator for almost two decades and tend to stick to exterior work during the warmer months. I’m a massive product geek too and have loads of repeat customers, so I know about the longevity of many different fillers on the market. When working outside, the most important thing for me is, how long will a job last before it starts to look tired!! For this reason, I thought I’d do a quick blog for the Decorators Forum UK and explain a bit about what I think is the best filler for long lasting masonry repairs.


The Secret to a Long-Lasting Repair


I have used several different masonry fillers in the past. A lot of them are too soft or can hold onto too much water. “all-purpose” fillers such as Tretrion and many others can be a nightmare!! This type of filler generally only lasts a year or two before they break down or damage a painted surface.


You need a filler which is going to adhere well to any surface, otherwise it may start to break away over time. You also need a filler which will set rock hard, not hold onto water and can be overpainted. Anything containing cement is a bonus because you know it will last!! For me, the only reliable and long-lasting filler you should look at is Toupret Murex.


About Toupret Murex


Toupret are a French company and seem to have a different filler for every type of job. Although being faced with so much choice can be overwhelming, at least you know each product has been developed without compromise.


Toupret Murex can be used in any size of repair. It will stick like sh1t to any surface, it’s very easy to sculpt into any shape and it dries rock hard!!


There are a couple of drawbacks; This filler needs around 24 hours to cure before you can paint over it due to its cement content. It’s difficult to sand down too, so don’t overfill!!


All told, this is one of the only exterior fillers I have faith in for long lasting repairs, certainly for larger repairs in softer material such as sandstone. Even large patches of render that have come away. Toupret Murex is so much easier to use than traditional render.


Other Toupret Exterior Products


As mentioned above, Toupret seem to have a different niche product for every specific type of job. Even masonry fillers!! Toupret Exterior Skimcoat is brilliant for smoothing over fine surface imperfections and can make large areas look completely flat and blemish free.


Another one to look out for is Toupret Touprelith. This product can hold onto water, so keep it away from sandstone or it won’t last. That said, it is easy to use, easy to sand and fast drying.

It’s a Decorators’ Job to fix bad Work

Why don’t builders take responsibility for completing their own work? It isn’t a decorators’ job to cover bad workmanship and make them look good!
