PeterW Posted September 11, 2019 Share Posted September 11, 2019 Use clear CTI as the edge is nice and crisp. And white discolours. Link to comment Share on other sites More sharing options...

So clear CT1 won’t discolour , mould , flake ?? In an external environment? Link to comment Share on other sites More sharing options...
PeterW Posted September 11, 2019 Share Posted September 11, 2019 @Nickfromwales clear CT1 doesn’t change colour does it ..?? Other option is grey or black, both are suitable for outdoors. Link to comment Share on other sites More sharing options...

White CT1 goes "near custard yellow" to quote the Welsh Wizard. 1 Link to comment Share on other sites More sharing options...
bassanclan Posted September 11, 2019 Share Posted September 11, 2019 Clear CT1 does discolour. I don't know about outside, but in a bathroom I fitted 6 months ago it's gone yellow - even though it has some natural light. What about using the same mortar as the stone?

Bitpipe Posted September 11, 2019 Share Posted September 11, 2019 Is there insect mesh at that interface? Link to comment Share on other sites More sharing options...
Onoff Posted September 11, 2019 Share Posted September 11, 2019 Kevin Cashin at C-Tec said something to me about white CT1 on the lines of it can be cleaned with a mild bleach solution I think to bring back the white. Link to comment Share on other sites More sharing options...

Essentially it’s the edge of the timber frame with insulation pir meeting the wall - foamed in the gaps . So this gap is just where the Renderer ended his bead .

Don’t want to get it on the nice render nor the stone . Suspect mortar that thin would crack and eventually fall out ...?! Link to comment Share on other sites More sharing options...
Bitpipe Posted September 11, 2019 Share Posted September 11, 2019 I always meant to seal the gaps where my render met the soffits (which were installed after the render). Never got round to it and not sure there's a massive benefit other than aesthetics as there's insect screen top and bottom and I'd never get up to clean it. Bit of a shadow gap effect. Anyway, as my render is likely need removed and replaced, glad I didn't bother. So my choice would to leave it be and see how you live with it - nice home for the spiders... 1 Link to comment Share on other sites More sharing options...
bassanclan Posted September 11, 2019 Share Posted September 11, 2019 OK what about a white frame sealant such as around windows. The concern being it won't match the render or the stone 1 Link to comment Share on other sites More sharing options...

nod Posted September 11, 2019 Share Posted September 11, 2019 I wouldn’t bother with silicone I normally tape the render with Jaffa taped and point with a motar gun Then flatten it down with a finger trowel I’m just trolling through my phone for a picture 1 Link to comment Share on other sites More sharing options...
soapstar Posted September 11, 2019 Share Posted September 11, 2019 @pocster Looks nice, very similar to what I would like. Can you tell me what K-Rend product you used and colour? I get confused with all the different products they have! 1 Link to comment Share on other sites More sharing options...

The front as in the photo is a different k product to the sides . Sides were thermolite front was render board . Colour is limestone white . It’s almost like ‘pure’ white but a bit off . Renderer recommended the colour other than pure white because any ‘ageing’ will be less noticeable. Link to comment Share on other sites More sharing options...

Just watch out for algae growth - blows onto the wall and gets into the finish and then blooms when it's damp - jet washing does not shift it (but will take the topcoat off your render) When I get mine replaced I will try and treat with an anti-fungal product. 1 Link to comment Share on other sites More sharing options...
nod Posted September 11, 2019 Share Posted September 11, 2019 K rend do an anti algi Pick a dry day Spray with a garden sprayer Let the rain do the rest over the next couple of days As long as you don’t use a turbo type Nozzle A jet wash will bring it up like new If you are looking for a very white white that can be applied on all surfaces The Sw K rend is a good all rounder 1 Link to comment Share on other sites More sharing options...

Using 4:1 building sand / opc, quite wet and sometimes it "blocks". Well mixed, no lumps etc. Sometimes works if you just shake the gun a bit. Is it redistributing the water or something?

Cheers I ideally mix a bit of SBR ion the mortar 4 .1 as you say It will come out sloppy But don’t teach it till it has thickened up Then I run a mastic trowel round It’s getting the mix just right rather than any skill with the gun Link to comment Share on other sites More sharing options...
Declan52 Posted September 11, 2019 Share Posted September 11, 2019 Clean it out every 2 fills. If it starts catching on the nozzel then you have no chance of getting it out nice and creamy. Link to comment Share on other sites More sharing options...
Construction Channel Posted September 11, 2019 Share Posted September 11, 2019 Probably not good for the mix but less water. More Feb seems to work well through guns Link to comment Share on other sites More sharing options...
