Exterior Wall - Uneven surface

Gus99

Hi - DIY novice here. Had a back wall built at the end of my garden a couple of months ago, and the guy rendered it, so that I could later paint it. Most of the wall surface is nice and smooth, but there is a section that is very uneven (to the left of the pillar in the first picture).

Does this need to be re-rendered, or is there any shortcut I can take (some kind of putty or primer?), without it looking shoddy? The second photo gives more of a close-up. Thanks in advance.

Thats the worse job Ive seen in my life I hope it was free

Back in the 70s there was a simple but effective solution to this type of work. One found the guy that did it, dragged him back by the short and curlies and stood over him gently tapping him on the head with a 9 by 3 until all the render was off and they then got a plasterer to do the job.

Jaysus op, i dont know how he did that, or what he was doing.

To be honest, i would get the wall capp'ed and re-plastered by somone compitent. Theres no real shortcut that will look anyway decent

You could probably try exterior poly filler? Paint wall first so you know what to fill (In this case the whole wall:p) Link

Before it sets rub over with one of those huge sponges (Dampen sponge first) to get a nice smooth finish....

mad m, Have you ever seen this done and how long did it last. Or have you ever done a similar job.???

My openion is that the OP should do the tried and tested way snyper suggests

The link says the poly filler is in a 1.75Kg pack so half a trailer load should do the trick, on the other hand I hear the rustic look is in thisyear

The cracked rustic look is also very popular.

Have used something like it before, and sets hard. The OP is better off painting it first, you'd be amazed what a couple of coats of exterior paint can do plus it can actually fill in some of that terrible plaster work, then if need be used some of that exterior polyfiller on the bigger holes, to try and smoothen out the rest of the wall....

If it was mine I would re plaster the lot of it and have the same look on it all. Your method may work but if he does it himself he will be spotting faults every time he looks at it.

Thanks all.

The plastering was part of a wider garden landscaping project, so the guy wasn't a specialist plasterer (he had originally intended getting someone else in for this, but was let down). 90%+ of the total area plastered is actually fine, and the bad area is a little awkward to access (just above a shed with a sloping roof).

Based on the replies, I wouldn't trust myself to get this right - I will get somebody in.
