So make sure that its tough to the touch. You don’t want it to be completely dry but you do need it to firm. If you push it still holds it shape then your good to go. Ensure substrate is dust, release agent and frost free and is suitable to provide sufficient support

This is where the funs starts and where the skill lies when you’re rendering a wall. Before we begin, you need to make sure that the wall has dried. You will never be able to render a wall whilst it’s still wet – it needs to be solid before you can start floating.Whilst we are aware that some customers have experienced challenges with some lenders, this is not the case with all lenders provided that the correct installation documentation is in place. This is a lot to take in and I understand that there’s a lot to learn. It’s a huge subject to follow and I know that some of this might not make much sense to you. However, knowing the process is one of the biggest things in rendering a wall. That’s literally all you need for the scratch coat. The only thing that isn’t a constant is the water. If your sand is wet than it will need less yet if your sand is dry then it may need more.

The best thing is to test it. So if you feel it’s a good time to start then give it a try. You’ll find 2 things will happen:The scratch coat is the foundation of the render and the base to the whole product. This provides strength to the wall but also has the most amount of waterproofing. This is what keeps your building water tight and stops any moisture from getting through into your house. First off, let’s talk about your weapon of choice which is the float itself. I recommend you buy yourself a Plastic Float at 11IN X 4.5/16IN which you can buy from the link here. This size is perfect, (especially for beginners) because they are so much easier to use compared to the bigger sizes. By deciding to simply paint over the existing walls with a hydrophobic and long lasting house paint, you are getting the best of both worlds – a home that looks great, and a finish that you can trust to do its job, and go the distance in terms of long-term property protection. The second scenario is that the render will move with the float but in a more positive motion. You’ll be able to apply pressure without worrying about pulling the render off and any areas that have little holes will start to fill with your movement. This is what we want!
