Here are the steps to installing block walls yourself!
Before you start rendering your wall, you need to prepare them by cleaning them with a stiff-bristled broom. This will ensure that the surface is free from dust, oil, dirt, paint or grease. And if needed, you can lay some sheets to protect your flooring. Then, continue to use the broom back and forth against the wall until it's clean. You can also add some soap to break up the material.
Furthermore, a smooth, dense surface with low absorption rates should be prepared with a dashing coat before applying the render. A dash coat is a potent mix of cement and water that is flicked over the wall or metal window frames, creating a surface for the render to grip. And before you begin to apply the render, allow the dash coat to dry for at least 24 hours.
In a bucket, add some water and the rendered product according to the manufacturer's instructions and mix it with a mixing drill. Then, continue to mix the render until it's lump-free and stiff enough to stick to a rendering trowel. You need to aim for a toothpaste consistency for the render.
You can use a garden hose to spray the wall down. Then apply the render with a steel trowel, spread it all over the surface. Use a straightedge to check for the level of the render. Then, allow it to cure for at least one day before you apply the paint.
Generally, you only need one coat of render and it should be 4-6 mm thick. You need to apply the render as smooth and flat as possible.
Here are the steps to install brick walls by yourself!
To render course bricks, you need to add some water to the surface before you start. There are two, different techniques to apply the render, you can place the hawk's edge on the wall and then brush up from there, or you can tilt the hawk onto the trowel and apply the render at a 45° angle. If your wall has vents, render up to the vent with a slight overlay around the edges, and then cut away when dry to finish.
Extend the render up towards the top of the wall, and then spread it in one solid motion. Continue to apply the first coat of render to the wall, making the render coats as even as possible.
Let the first layer of render dry for about 30 minutes. Then check the dryness after this time, but expect it to take about two hours to dry completely. Before you lay the second coat, this layer must have adhered to the wall.
Next, you need to float the wall to fill in some small hollows. This will close the surface to make it more durable. Depending on how dry it is, you may need to add a little water as you work.
The last step is to sponge down the render for a smooth and excellent finish. Use a damp sponge for the perfect job. And then, rinse out your sponge as you go to avoid a scratchy finishing.
