Your rendered walls are the frontline defence for your home. Not only do they work around the clock to hold the building up, but they also prevent the great outback’s elements from penetrating through into your home. Proper rendering in Brisbane that is well-maintained can also keep the interiors warm and comfortable. Whether you choose acrylic or cement render for your home, if you want them to stay in good shape by resisting the continual thrashing of the elements, it all depends on you as the homeowner. You should quickly identify early signs of failure in the rendering and put them right. Maintaining your rendering and carrying out render repair work where necessary is vital.
When does render need repairing?
Is the rendering on the external walls of your home cracked? We think that you’ll know by the looks of it that this is not a good sign. Cracks can become serious issues for the underlying structure beneath the rendering and must be attended to. If you leave them for too long, the problem will get worse and will cost more in the end to fix. Several cracks on the outside of your house should never be ignored, and you need to resist hiring an unlicensed technician to hastily patch the job up by filling it in with some cheap silicone mastic. Hire a professional Brisbane rendering company to keep your rendering in good condition, and you won’t regret it.
Some cracks cannot be avoided because render tends to crack over time. Sometimes, the wall behind the render surface moves or breaks, which means that the render will too. That means that the cause is sometimes linked to structural movement. Traditional lime render is more flexible and forgiving than modern cement. Consider rendering formulas that have more flexible recipes like polymer rendering installations to give your wall added protection against cracking. There are many more reasons you should consider rendering, but the resilience against elements is a big one.
What causes cracks in rendering?
The most common cause of render cracking and bulging is moisture entrapment between the render and the wall. This is the most common cause of tiny hairline cracks, and that’s precisely why you need to do a consistent job of looking out for them. They should be sealed immediately when they first develop because the longer you leave them, the more water will penetrate the gaps and expand, blowing the render surface loose — resulting in even larger cracks. Once damp becomes trapped behind the surface, it can penetrate through solid walls, setting up the conditions for structural decay within the building.
How to repair cracks in rendering?
In most typical cases, only surface-level render repairs will be required to handle small cracks. The technician’s first mission is to get rid of hollow, loose or cracked render, which will leave exposed bare patches of wall. These patches will need time to dry out before a new render is applied. Small cracks can be filled with all-acrylic or siliconized-acrylic sealants. The caulk can be peeled away easily when you do. It gets a little complicated when a large area needs a rendering repair job because it is a skilled job.
It’s important to note, though, that while repairs are possible, the repaired or patched area will look different to the rest of the old rendered surface. Even in the most experienced rendering hands, ‘invisible’ or ‘seamless’ repairs are hard to achieve, so you may need to allow for the redecoration of the whole wall. The wall could be covered with a cladding of our choice, such as traditional tiles hung from battens fixed over the old render. It can be challenging to match the colour of the rendering perfectly. So if we’re working with a surface that requires many patches, you may need to consider the easier option of covering the whole surface, once patched, with cement-based or acrylic exterior paint.
