Planning to render a Launceston home? Why temperature, rain and drying time matter, and how to avoid cracking and patchy render.
Launceston gets plenty of cold mornings and long wet spells, and both affect how render goes on and how well it lasts. If you're planning a render job, here's what we look at before we start.
Cement-based render needs time to cure. On cold days it sets slowly, and if it gets close to freezing overnight the water in a fresh coat can damage the surface. That's why we watch the forecast and avoid applying render when overnight temperatures are expected to drop too low.
In the Tamar Valley that usually means planning bigger jobs for spring through autumn, and keeping winter work to smaller patches and repairs on milder days.
Render shouldn't go onto saturated brick or block. After a week of rain, walls can hold a lot of moisture, and rendering over it can lead to bubbling, staining or poor adhesion. We check the substrate and, if needed, wait for a few dry days before starting.
A traditional sand and cement render suits most brick homes. Acrylic render has more flexibility, which helps on surfaces that move a little with temperature changes. For lightweight panels like Hebel or foam, a purpose-made system is a must. Our acrylic rendering and cement rendering pages explain the differences in more detail.
If you're still weighing up options, it's worth reading about how professional rendering is done step by step, from prep to the final coat, so you know what to ask any renderer you talk to.
Hairline cracks let water in, and in a cold climate that water can expand and widen the crack. Fixing small cracks in autumn, before the wettest months, usually costs far less than repairing larger sections later. Our render repairs service covers this.
