Yes I think you are right - it’s ok at the moment but in the long run a new structural supporting pillar (not offset) under the corner would be the plan - we never used the undercroft for a vehicle anyway.
That was just an initial quick cleanup to remove the flakey bits - of course as mentioned I’m going to try to remove more pitted stuff and get more bare metal showing but I can see where bare metal begins now and it looks treatable. The integrity of the vertical “I” section and the top...
Ok so initial clean with vibrating hand tool looks ok - there was some delaminating on the bottom horizontal of the beam and that section has maybe lost a quarter of its thickness - vertical section and top horizontal seem to have remained original thickness. Will get a knotted wire brush on it...
I think what you see as delaminating or spalling is mostly the large amount of direct to rust paint and wax oil I put on last year without grinding it down - the beam underneath has a lot of surface rust and a little spalling but is not delaminating ..…..yet !
Very good shout mate - two handed tools up a ladder was not a great idea :oops: - I think i'm going to go with a twist knot wire cup that fits my small hammer drill -I can operate that one handed while hanging on.
Once red oxide is on and dry any recommendations for a paint to topcoat over the...
Thanks - Galvafroid looks good but I’m not 100% sure the beam is galvanised- I suppose sticking out and exposed in the way it is the original builder should have used galvanised but I can’t tell.
It’s not a wall it’s a square supporting pillar part of the original construction like the one at the back corner which isn’t offset - the front one is offset to allow a vehicle to get under if needs be.
Hi - I have an exposed RSJ supporting a first floor extension (about 30 years old). It was boxed-in but the wood had rotted around it - so I removed the wooden boxing. Once exposed the RSJ looked a bit rusted so I wire brushed it, painted it with rust eater and then used waxoil to protect it...
