Hi all...
Wonder could somebody help me with this...
Been working with nhl past few years at my own place and parents. Couldnt find anybody in the area that knew anything about working with lime never mind tackle it.
So been working away myself past 2 years with great success. Lots of research...started with few small areas as tests then progressed to whole house inside and out and lot of garden walling etc.
Completed a lot of curved and sculpted areas to date...everything has worked out a way beyond my expectations.
Trying to get some std block planter walls finished up before it's too late.
NHL 3.5 lime
Scud coated as per usual 1 lime 1.5 washed sharp sand. Harling trowel applied.
Walls dampened day before. Light dampening few hours beforehand on the day.
Scud coat lightly misted first few days afterwards.
After a week the scud coat was still brown and easy to break bits off, crumble in fingers. No cracks at all.
Never experience this before...lots of conflicting advice given to me... but wasnt happy so scraped off scud.
Weather had changed by now so bit less dampening and only one misting afterwards.
Scud came up well.
Left a week. Covered with hessian and tarps.
Applied 10mm float coat on Fri. It's been covered with hessian and tarps since.
Opted to not mist as whilst it was covered up, it was raining non stop all weekend.
Just giving things a little check over today.
Render still brown, hasn't begun to lighten up. Im assuming things are taking a while in current conditions. Even when the suns out, not much drying happening outside.
Tapped over a few areas just as a check...surprised I am getting a hollow sound over a few areas. Solid sound in others.
Lightly chipped a small area just to be sure...seems well adhered...stuck fast...no bits break away.
Cant decide whether the hollow sound is just because they are raised planters and currently hollow in middle or wether it is an issue with the render.
I was expecting it to come off readily but the patch I chipped at seems well stuck on there. Chipped right back to the block.
Melting my brain standing here by myself. Panicking a bit as haven't used lime this late in year so a little anxious to get things finished up. And it's a hassle trying to keep planter walls covered and protected as cant just hang sheets like with a basic wall. Have to keep covering and uncovering etc.
Just wondering is there somebody with some experience whi could possibly advise?
Many thanks in advance
