Rendered raised beds
Anonymous user 23/02/2024 - 3.19 PM
I am looking at building some raised beds at the back of our garden and would like a smooth rendered finish, probably a light grey. The beds will only be about 4 course high. Are concrete blocks the best to use and how deep does the footing need to be and how do you apply the render? Do I need beading to produce a crisp edge at the corners? And can the render be painted? Many thanks for the advice
Are you a tradesperson and able to answer this question?

100mm will be substantial enough for your bed 'load' with an escarpment (wider than thickness of wall) of 75mm. I'd use steel reinforcement-bar through foundation too. Concrete block are adept to your project, use a sealant such as Thompson before applying render. For render I'd recommend K-Rend base coat (scratch coat) & K-Rend Top coat (finished coat). Yes you can paint although if going for white or ivory I'd simply leave the render as is but if you want to colour a quality exterior paint will take. Ask your local merchant on best to use

If the blocks are on flat (400mm total height) then you would be more than fine with a 6 inch footing. If its blocks on edge (850mm total height) then id say you might want to go down to 8 - 10 inches.
Concrete blocks are fine to render too, just make sure you use a sealant and or some PVA / SBR to help it adhere. Beading makes the job look 100 times better as long as its been attached straight. render an be painted with a good missionary paint but silicon based renders (like K Rend) come in a range of colours anyway.
Hope that helps.
