Exterior rendering is a bigger decision than internal plastering, and it starts in a different place. Not with a product, and not with a colour chart — with the wall that’s already there. Bare brick, sound smooth render, painted render, old pebble dash and failing render each lead to a different job.
If the render is cracked, hollow or starting to come away, it’s worth understanding why before simply covering it. New coats can only hold to what’s underneath them, so the condition of the background sets the options.
Sometimes that means a repair to a sound elevation. Sometimes it means removing an old finish. Occasionally it means leaving good original brickwork alone, which is a legitimate answer too.
Silicone render: a modern coloured system offering a clean finish with good water repellency and vapour permeability where correctly specified. Colour runs through the finish rather than sitting on top as paint.
K Rend: a recognised branded rendering system rather than a generic name for every type of render. Their range includes silicone-based finishes, which is why the two names get used interchangeably.
Monocouche: a through-coloured render applied in one process and usually scraped back to an even texture. Straightforward, hard-wearing and popular on newer housing.
Traditional sand and cement: still appropriate in plenty of situations, particularly for repairs matching existing work, and typically decorated with a masonry paint or mineral coating.
Rendering can form part of improving an external wall, but if there are signs of damp or persistent moisture, it’s better to understand where that moisture is coming from before simply covering the surface. Diagnose first, finish second.
External wall insulation may be relevant where walls feel cold, but it’s a building-system decision rather than a finish — wall thickness, window reveals, sills, roofline and ventilation all change. It isn’t the same thing as re-rendering and we won’t present it as if it were.
Exterior work can sometimes move with the weather. Heavy rain, frost, low temperatures and rapid drying in strong sun all affect render, and every system has its own conditions in the manufacturer’s instructions.
Getting the conditions right matters more than forcing the finish onto the wall on the wrong day. On Wearside that occasionally means shifting a day or two.
If you’re changing the exterior appearance of an older property, particularly in one of Sunderland’s conservation areas, it can be worth checking any local restrictions before settling on a finish. We can’t tell you whether permission is or isn’t needed — that’s a question for the council.
Older brickwork isn’t automatically something that ought to be rendered. Original materials are worth respecting.
Exterior area, number of elevations, the existing finish, how much removal or repair is needed, the render system, scaffolding, access, windows and detailing, preparation, property height, and weather logistics. Published “from” prices for rendering tend to describe a house that isn’t yours.
Send a few details and photos if you have them, or ring and talk it through. Either way we’ll help you work out what the wall actually needs.
