render

I’m looking to repair a crack in some render but I’m not sure how the original finish was achieved. I’ve attached a couple of images, does anyone know how this effect is achieved? I initially thought it was a tyrolean gun finish, but it seems too smooth in between the bumps for that to be the...

Hoping for a bit of advice. We have a single garage not attached to the property, but shares one wall with the neighbours garage. Since it’s too small to fit most current cars, I’m looking at converting it to an office, and to do this would require blocking up the garage door, which I’ve come to...

Morning all. Currently doing some repairs on my 1897 Victorian house. I am pretty certain that the solid walls are ashlar facing with a rubble backing but trying to figure out the material of the ashlar itself. From reading, it could also be Ashlar render which was popular in 19th century. You...

Hello all, I have Internal aerated concrete blocks (aac) that have been painted. I've read https://www.diynot.com/diy/threads/wet-plastering-aerated-lightweight-blocks.177624/ And I'm undecided on what I need to do. 1. Do I render? Then skim? (What's difference between plaster) 2. Originally...

Hi all, We are currently having the blown crepi on our house repaired. The house is concrete construction and has a thin layer of a type of crepi followed by paint (sorry, I don't know what crepi is in English, I am in France). The builders have scraped off the loose crepi, and opened out any...

Looking for some opinions on this, new driveway with new rendered block Wall. 50mm gap between beading and driveway block on the right and no gap on the left Builder is suggesting that this is for drainage…. Makes no sense to me. Does this require completely removing and starting again or can...

I'm thinking of doing some work on the gable wall of our house and would need scaffolding installed. Set back ~30cm (is that gap allowed?), from the part of the wall to be worked on. This would be to allow some repairs to cracks in the render of the wall, some repainting, and then installation...

Hi All, I am after some detailing guidance with regards the interface between a stone Z slip plinth adhered to blockwork up to DPC, abutting a render finish above DPC. The wall I am building will be dense concrete block (it is not built yet). The stone slips I am thinking of using are 25mm...

Hi all, Looking for advice regarding render and DPC. Looks like old tar, the removed render had been serverely damaged by frost, the bricks too. My thinking is, remove copes and use a modern DPC. Then ideally a lime finish like a this Lux product...

I`m planning to render the tired looking and over painted 1930 pebble dash. I know someone will say to remove the pebble dash completely but doing that would cause load of vibration and crack on a fully refurbished house. I was thinking to nail the EML mesh to the existing render than 2 coat...

Moved into our property (built in 1889) in May. Following some recent rain an internal wall has started to show signs of damp. Think it’s penetrating through the gaps in the render/plinth (see pics) any advice on how best to repair? We are complete novices so will likely need a professional, but...

Hi everyone, Does anyone have any idea what the source of this cracking might be? It's a 1960's house with brick walls at ground floor measuring 300 mm thick, the first floor (front and rear elevation) is rendered and measures around 260mm thick so i'm assuming it's a different walling...

Hello! I am a new homeowner and completely lost in the dark. I have noticed some spalled brickwork at the bottom of my side wall. No damp on the inside, think they’re just old and weathered. Any advice? Do they need to be removed? Or could I get away with repointing and the getting render on...

Hi, Landscapers have built a new retaining wall, steps and raised beds. Retaining wall is lined with DPM and weep holes at bottom. It’s going to have K Rend. I’ve got a few questions before they get started with this stage to ensure it lasts as long as possible. I will ask them too but I know...

Evening, I have this hole in the render outside in the wall and I want to fill it in, it's a solid brick wall and the dpc is stepped, the porch dpc is highier than the original wall. I filled the hole in originally with lime nhl 3.5 and finished in lime wash, hoping it would breath and...

Hi All, I am going to render the walls after my Extention completion. The question is - I'm extending the backside kitchen (single floor), for the roof, do I need to fit the lead into the wall and cement it? my roofer says just nail to the wall and render will cover that and no water will go...

Hi all, Looking for some assistance on wall build up for a SIPS systrem (I am using the Kingspan TEK system if that helps). The outside of the SIPS panel have been wrapped with a breather membrance and are then to be clad with 50mm rockwool, which will then be rendered using something like EWI...

A chunk of render (?) fell off the side of the roof on my single storey extension last week. See attached pics. How should I approach fixing this? It looks like I should be able to just trowel something back on after maybe brushing loose material away. I'm trying to avoid buying a sack of...

Hi, I've got a 1930s Semi with solid brick walls and the original roughcast render, which presumably will contain lime for the solid brick to breathe? What's the best way to go about improving the look of it? as it's showing its age and doesn't look great. Had quotes to hack off and re-render...

Hi all, I've had walls built in my garden and they've mostly now been rendered with K-rend. I've noticed that I can see water coming through the render - especially seems to be tracing the pattern of the mortar (see photos) Is this just part of the normal drying out process or is there...
