We had our old hot water cylinder removed when we had a combi-boiler installed. This has now left us with a fairly large and useful cupboard in the back beroom. However, years of heat from the cylinder has caused major cracks in the plaster on one wall.
Last night I knocked off all of the loose plaster to reveal the layer beneath (looks like cement on top of the breeze blocks, with swirly horizontal lines scrawled in, presumably to let the plaster grip?). Some of this layer has also cracked (~2mm) but it at least still seems very solid.
What is the quickest and cheapest way to fix up this wall? I don't need a perfect finish as we will only use the cupboard for storage. Shall I just buy a bag of plaster, or would even a light skimming of cement do? I have only ever used patching plaster before so don't (yet) have the kit for mixing larger amounts of the real stuff.
