Belzona 5122: Does it work?

Back in February this year we applied a couple of coats of Belzona 5122 (otherwise known as “Clear Cladding”) to the south west gable and above one of the rear patio doors.  These areas were particularly prone to the south westerly weather and we felt we needed to treat the stonework to prevent any water ingress.  We put a couple of coats of Belzona on these areas, but I was never quite sure how effective it was going to be.

Well, today, with some very wet weather, we have the clearest indication ever that the Belzona is doing what it is meant to do.  Just take a look at the photos below.

The area above these patio doors was treated with Belzona 5122 in February this year.  Here you can see on a particularly wet October day, the effect that it has had.  Just compare it to the stonework above the patio doors on the right.  You can even see where the Belzona has dripped onto the jambs and the step below.

Here you can see the impact that the Belzona has had on the way the stonework is absorbing the rain water.  I hadn't really noticed this before as there is no impact on the colour of the stonework when it is dry.

The left hand side of this south west gable was treated with Belzona 5122.  On this particularly wet day, you can see the difference it is making to the way the stonework is absorbing the water.

Clear Cladding

The gable nearest the roadside is South West facing and as a result tends to get a lot of bad weather.  This has obviously been a long term problem since the interior of this gable end had been dry lined previously.

We have put a waterproof membrane on the inside of the all, but decided that a coat of a silicone sealant would do not harm.  We decided to use Clear Cladding from Belzona as this is a micro porous silicone product and as such allows the wall to continue to breathe.  This is an alternative to Sovereign that seems to be popular with many builders.

Clear cladding is expense – it is around £100 for a 1 litre tin – however, this concentrate is diluted before it is applied and a small amount seems to go a long way.  The product dries clear and it is difficult to tell where (or not) it has been applied to the wall.

Clear cladding is a silicone based product that is used to seal stonework and mortar.  This concentrate is mixed 1:9 with water.  As a result a small amount goes a very lond way.  It is important to make sure that you don't get any of the solution on glass as it is nearly impossible to get off!

This has now been treated with clear cladding.  It was done the previous day and you can tell the bits that have (and haven't) been coated.  Let's see if it works!
