'Homeshield' wall coatings - thoughts?

Bendy_House

This arrived as a circular today. It wouldn't be for me, but potentially for sil, who will need her rendered house painted in something in any case.

On that point, her house is done in K-Rend, 'silicone coloured render'. The house is a good 15 years old, tho', so presumably will have weathered enough for a top coat?

Anyhoo, are these coatings as good as they claim - 'never have to paint your house again'?

Is their 15-year guarantee bullet-proof?

Thanks for any thoughts or info on this.

K-Rend is a self coloured render, so shouldn't need repainting unless she wants a change of colour.

If their 15y guarantee isn't insurance backed, then it will only be worth the paper it is written on for as long as the company is in business. And check the exclusion clauses for cop-outs.

Cheers, FB.

Yes, K-Rend is meant to be permanent, but it's had a grey-mortar repair to around the front door due to a moving frame which crumbled the 'Rend. It's also looking pretty tired in general, with lots of vertical 'rust' stains.

So, it's going to need painting, one way or t'other.

I would suggest giving it a good scrub (perhaps even jetwash) and then brush a coat or two of silicate paint on. Patch up any dodgy areas first and maybe apply a primer.

Yes, any repaint would begin with a jetwash - it badly needs it. And I know you can get 'silicone' refinishing coating by KRend to freshen up the colour.

I'm not sure, tho', whether their 'paint' will colour a strip of grey mortar evenly? I can ask them of course.

I just wish to gather as much info on the options as possible; normal masonry paint, I've been told, will adhere without any issue now the render has fully weathered. KRend is an obvious alternative, but I don't know its benefits or how the cost will vary. And then there's the supposedly advanced coatings like 'Homeshield'; has anyone here had any practical experience of this? Or 'know' about it from a technical pov?

Is it a type of epoxy paint, even? I've had experience of 2-part masonry paint when helping to paint a village hall at least 10 years ago; it is truly as white and bright as the day it was put on - awesome stuff.

According to their sales blurb, Homeshield is a blend of minerals, acrylic resins and fibres applied with a low pressure (airless ?) spray system. Without seeing the technical data sheets, I wouldn't like to say if it is a two pack system, although the use of acrylic resin suggests that it is.

Mind you, they also claim that their product is silicone based, micro-porous so allows walls to breath - The latter claim I would take with a truck load of salt...

Whoa there. Silicate paint and silicone paint are two VERY different things. In this case, I assume you mean SILICONE paint, as the surface is not (entirely) mineral base?

Bendy_House

I assume FB means the stuff supplied for this job by KRend.
