Door canopy/porch repair

[jwelch]

Hi,

Could anyone advise us on how best to repair this front door stone canopy? We have water getting into the internal walls and wonder if this might be the culprit. There seems to be a layer of what looks like concrete or stone that is crumbling and cracking that could let water in. Could we simply chip away the crumbling stone and resurface with a suitable material? If this is a straightforward job what is the best material to use to resurface the top of the porch. Any help appreciated

I would say the best long term option would be to get it covered in lead. Code 4. A layer dressed over then with a flashing strip let into the mortar join two bricks up.

Like this image, but really lead, not GRP!

Thank you, would you say that’s a job a novice could do or are we better trying to find someone to do it? What would you think the material we currently have on there that is crumbling might be?

Material appears to be natural stone which is eroding. Nothing much to worry about. Just getting wet and freezing, then sun etc etc.

Leadworking is not easy to get to look very good if you are new to it. Alternatively you could apply some WT1....

Thank you for your help, that WT1 looks like a good solution actually

jwelch, good evening.

In that location Lead is a temptation to a felon??

Sad but true, easy to access and fast?

Must say I have never heard of or used WT1

as above, lead will get ripped off in quick time.

clean off the top an clean out the crack.
fill the crack with a gunned in polyurethane cartridge.
coat the whole top withWT1 or cheaper similar stuff..
then float a layer of semi-dry sand and cement into the tacky WT1.
slope the sand and cement to falls so thers no ponding.
finally after the mortar is dry 24hrs coat again with WT1 or similar.

THank you! I have some WT1 on order, is there a type of polyurethane that is best to use for this type of job or would a standard sealant work ok?
