My garden wall looked more shabby than chic, particularly against my lovely new raised beds.
After carefully calculating the surface area, a bit tough as it was too high to measure. I bought a tub of Santex Masonry Paint (£24.99 from Screwfix), half the price of Dulux Weathershield.
To prepare the wall I pressure washed it and used a stiff brush.
The paint went on fine, I used a long handled roller for the high bits (and my brother up a ladder).
And the final look:
Much better! Just the trellis left to go back on and I have something special planned for that…
