Plaster over steel beam and columns

[Quintin79]

Hi Guys

im just about to remove a wall and replace with 65x65 SHS steel columns and a 150PFC. the existing wall is hardwood 75mm stud.

the question is how do you plaster over the beam and the columns? the steel will be quite thick and make drilling or self tapping prohibitive.

if you had a steel beam hanging down from your ceiling, how would you plaster it?

thanks

Normally we would just glue the sheets to the columns with stud adhesive.

The beam needs to have timber shot or bolted on to the top or bottom. Then cut an fold the sheets around the beam with stud adhesive on the beam and screw the timber.

To cut and fold you need very acurate measurements and straight cuts on one side of the board so fold the board will flod into a U shape that wraps around the beam.

To get the measurments right experiment on an off cut first.

I normally fix it to one side of the beam first before snapping the sheet. that is if the timber is on the top of the beam.

If you have shot timber to the bottom of the beam then I would fix the sheet to the bottom in position to fold the sides up, which are glued to the beam with stud adhesive. Then bace the sheet back to the beam until the glue is dry (24hrs).

You could do it without the timber and just stud adhesive, but you would need to prop the sheet in position from underneath as well as the sides until the glue dries.

I hope that is clear enough.

Cheers Rod
