We've been tasked with repairing a concrete area to a small garden
It's got lots, as you can see from the initial shot. It's got lots of small cracks which we've widened up to make sure they can take some repair
mortars and stuff. We are going to use products from a company called Resistall who make an amazing array of repair products
and surface coatings for just these conditions. This particular one is a deep fill repair mortar
We're going to use that to repair this deep hole in the concrete
And the instructions come on the lid. It's a two parts. There's the hardener inside the tub with the resin
We're going to mix that together with a paddle mixer. You'll see that being used. We're going to use the trail to put it into the hole
and then we're going to clean our tools and everything down with some safety solvent from resistor
People ask us quite often why do you use epoxy mortars rather than concrete when you repairing holes Well this particular job this is going to be painted It needs to be hard It needs to be 100 waterproof
Concrete when it dries develops tiny little fissures, tiny little cracks. Water gets in those. In the winter, that water expands when it freezes
That makes the crack bigger. More water gets in and so on and so. It's called freeze-thor action
That doesn't happen with epoxy repair mortars. they don't shrink back, they stay smooth
and they're really very, very workable. The main drawback with them is that you don't get long to work with them
This one we've got 20 to 40 minutes to do, which is going to be to use it
That's going to be plenty for what we want to do. So we're going to mix it up and get on and you'll see it being used
Okay. What you've seen is me using the epoxy deep fill
in two pretty deep holes This can be used up to 150 millimeters deep believe it or not That incredible But it quite coarse aggregate So when we get towards the top I like to feather that out to get it a little bit smoother
And we need a finer aggregate for that. So watch the other video about us using the epoxy repair mortar grey
And that will see that it's a finer aggregate. It allows me to smooth it out a little bit more
You'll also see another video about a fast flow mortar that we can just tip into these cracks
So this is the deep fill repair mortar. Please wear the proper PPE equipment. We're used to this stuff. We're doing it all the time. Our skins like leather, but you'll need to wear some gloves and goggles and stuff. So please do. This is an incredible product. This will cure very, very quickly now. Light traffic four to five hours, heavier traffic up to 12 hours. And we're going to do all of these cracks and then paint the surface
completely. So another fantastic product from Resistol, we're very, very pleased to be able to use it
