Really enjoyed this series. By far the best I've found. Thanks. Regarding the start to stiffen when in the bucket 3:16 maybe suggest covering the mix with a lazy damp rag/hessian or some plastic.
Really glad you enjoyed the videos. Yes it is a good idea in warm or windy weather conditions to cover the mortar in the bucket with wet hessian or plastic to prevent it drying out too quickly.
spoke to a bricklayer in the family who's been working 30yrs + in the trade for a company and asked about lime rather than sand and cement. He said only once has he had to use lime and that was on a listed building. Logic tells me, as long as the brick face is exposed and the building uses cement when built then using lime makes no difference because immediately behind it is cement...it doesn't make sense to use lime unless the brick was laid using lime?
would you say a ratio of 3:1. sharp sand and 3.5nhl is right for re laying any damaged bricks in a house in the west midlands birmingham. i was told the ratio depends on the climate
Hi there! It's difficult to suggest mortar mixes without knowing the location on the property (ie. chimney/wall etc..) and brick type. It could be that a 2:1 course/sharp sand and NHL 2 would be more adequate.
3:1 is what I used for a property exposed to coastal north westerlies where the facing was of beach cobbles, a la Norfolk/Suffolk. These are much harder than brick of course. Some of the work was done nearly 20 years ago and has shown zero cracking or shrinkage. I put that down to making a mix that was only just wet enough to make it workable, applying and packing it tight in the joints, by had rather than trowel. NHL 2 may be OK but that really depends upon the type of brick and how exposed the face is to severe weather on a regular basis.
Good question! The hessian, sprayed with water to keep it damp, stops the mortar drying out too quickly in warm, windy weather. Lime mortars need time to carbonate or harden.

A real master at work.
Love it!
Absolutely! Lynn is very talented.
I've got a 1975 build. Can I use a sand & cement mix to repoint the chimney brickwork? A Lime mix is for much older builds, is that correct?

Cool video, some cool tips for sure.
Excellent video, really well explained
Thank you for watching!
Use mini Grindr to cut the joints out much quicker do no damage to the brick work 👍
Superb set of vids
Thank you!
Thank you

May I ask why you left the gaps in the pointing on the bricks lower down on the stack? Or was it just to demonstrated how to do a small patch?
Hi. What is the mix?
Good job save the brickwork from that nasty cement mortar pointing does more damage than good l. East away at the lime mortar doesnt it ?
Thank you!
Why the hessian?
Good question! The hessian, sprayed with water to keep it damp, stops the mortar drying out too quickly in warm, windy weather. Lime mortars need time to carbonate or harden.
The pigeons will enjoy looking at that.
Chimneys 9 inch not 4
Hi Richard, this particular chimney is just one brick deep which is 4 inches
@@spab1877 oh okay buddy that's a little unusual tho
@@richardgrimbleby7853 Don't know what chimneys you've worked on but they are always single brick i.e 4 inch.
