how to fill this in!

[sandblast]

hello all!

wonder if someone can give me some advice on how to fill this in so it matches the rest of the wall

this was previously the frame of a fitted wardrobe which i removed, and still have a little more of the timber to remove at the top.

i have previously used toupret with success for smaller jobs, but i suspect this is more complicated because it's going on to the blockwork

i don't know wether to cut a strip of plasterboard and put in the gap then just fill either side, or fill the whole lot..

would appreciate any help!

thanks!

Fill the whole lot; consider hardwall for the majority of the infill on a high suction background like thermalite

As a decorator, I would a chisel to remove the old caulk. Then sand the area with 80 grit paper on a 150mm random orbital sander.

I can't see how deep the chase is, it doesn't look deep enough to use plasterboard.

As per @robinbanks you could use hardwall- and the top it with Toupret filler or similar. Alternatively, just use Toupret TX100.

thanks both! appreciate this info. i now know that those are thermalite bricks!

the chase is 9mm deep. i thought that was plasterboard on each side of the chase hence the suggesiton, but i may be wrong.

whatever, i'll do whatever you guys suggest! am i better off using hardwall then toupret or the tx110 for the whole lot?

Per cm, hardwall will be cheaper, but the bag size will be 25kg.

hello, so, as instructed, i hardwalled the chase. a friend then said to me, "great, did you wet it first?"

i did not. i put the hardwall straight on to the thermalite blocks.

if this was an important step i'm really baffled as to why no-one mentioned this to me.

can someone please tell me if i need to remove all this hardwall and start again, or will it hold?

if it needs to be done again, how do i remove it? and then when i do it again, should i use water, pva, or gyprime?

Before it sets, scrape away the excess.

With regards to the level of suction in the thermolite blocks, you might be OK, it is only a small area.

hello

what do you mean the excess?

i did this a few hours ago and it's nearly set now.

can i not just sand it?

 

[opps]

Sanding it will be very difficult. Scrape away the excess if you can and use filler over the top.

thanks for this tip

i have shaved off what was about 2/3 mm of excess; it's now level with the wall or very slightly under

Are the two sides of the plaster, exactly the same level?

Always completely flatten the plaster, alongside a chase, first, before beginning to plaster.

Never try to fill any depth of plaster in one go, fill in at least two stages, leaving the previous stages below the final level, and rough faced. Your final layer, needs to be well wetted, and polished to flat and even.

The vertical panel, ought to have been removed before you got to plastering, it will look odd if left in place. I would not expect it to be supporting anything at all.

hi harry

yes, the two sides of the plaster are exactly the same level.

the chase was 9mm deep so i thought it would be be okay to do that in one go, but i'll bear your advice in mind for similar jobs.

yes, the vertical block of wood was removed before i started. i decided to keep the horizontal beam above.
