mortar or lead mate?

[mattu27]

Quick one for someone, need to seal some lead flashing that I've installed but I can't decide on what to use.

The mortar is a light sand colour and I can't seem to get anywhere near sand tone.

Tried with yellow building sand and rugby cement alongside mastercrete in all ratios and all I can get is grey.

I've seen that you can get lead mate in a sand colour but nothing available at my local shops and roofing centre.

Does lead mate have a resin in it that sets hard or can I use a sand colored silicone instead? If so, which modulus would I need?

Thanks

Thanks for the reply as always. I did read that but didn't fancy paying the £12 a bag for a handful of mortar. I've got about 4m of pointing to do. Is it a no go on the sand colored silicone?

Thanks

Lead mate or silicone is designed for those that can't point and it's always a poor second choice.

Proper mortar, even a different tone, if done right and cut nicely will always look natural and like it was meant to be.

Silicone, sand coloured or not is unlikely to match the existing mortar and will always stand out and never dirty or fade and will never look right. If you're going to use lead mate, then I would suggest to use the lead coloured variety and then it looks like it was meant to be, not like a random attempt at something.

This is what happens if you use the wrong silicone ,I took this off a conservatory a couple of years back
