Capping an external wall How to grout (overhang)

[chossy]

Hey folks new to DIY and this forum. Could you guys give me some advice or tips on how to place tiles on the top of a wall to finish it off... I was going to use mortar to fix the tiles to the wall. Also the tiles have a 2cm overhang on each side of the wall and I wondered how I might grout the spaces which are in the over hang? put masking tape around the edge to hold the grout in place while it dries?

thanks for any tips
cheers.

What type of tiles are you using?

Hi cheers for having a look, they are slate natural things, the reason I wanted to use mortar was because the wall has a finishing strip on for the render, the inside side is going to meet a lawn, so I figured if I used mortar I could level that lower side up easily. I have attached a couple photos, hopefully you can see whats up from them...

thanks again,

It all depends on how thick your bed of mortar will be for the slate but if you have a steady hand and your confident with using a Silicon gun, why not get some appropriate Silicon that withstands all types of weather and use that to seal around between the wall and slate. I'm saying that because it looks like you have a lovely clean rendered wall and applying grout could and might run down that clean render when you try to clean it and smooth it .

Having said that if your bedding the Slate in mortar when you tap it down to ensure full coverage you'll be able to point to edges with the mortar that will squeeze out.

Hey thanks for the idea of Silicon... I hadn't considered that, I am pretty good with Silicon... I am very comfortable with mortar.

cheers, for the help.

Aye, l think mortar would be okay in this situation, as it looks like you will need a fairly heavy bed. As for the pointing, if using mortar it will crack through time. To make the mortar more flexiable and bond better add SBR , about 1ltr to a 25kg bag mix should do.

is it a natural slate , you are using? Are you intending to slope the copings to the inside?

No the slope is there because the guys who rendered the wall used a wee edging strip to give a nice finished edge... that's why I was thinking of mortar as the bed so it could build up the inside quite easily. Or I could just whack on another edging strip on the inside edge. I'd still probably go for mortar as I'm happy working with mortar... It may be a good idea to slope away from outside edge... maybe reduce the amount of cruddy water dripping down nice white wall....
