Screed battens fixed to wall to help level render See our project on fixing to masonry to accomplish this. These are 15mm thick wooden battens, which you fix to the wall. If you have a wide wall to render, setting up screed battens can be very helpful.

Mixing in a wheelbarrow is fine but almost always there is a little unmixed sand and cement at the bottom which does not become apparent until emptying out the barrow.ДЄ mixer is the best way to mix sand and cement render How to Apply Render to Your ExteriorWalls The best way to mix the render is with a cement mixer as this ensures that the mix is even and that the correct amount of water is added. See our project on Freeze-Thaw action for more information. This will also freeze and so the process goes on. If it is allowed to freeze it will expand and on thawing it will leave a void which will again fill with water when it rains. If it is likely to be very cold in the evening with even a hint of frost or ice, then the work must be covered (preferably by hessian sacking or even a old blanket) to stop the water in the render freezing. When rendering a chimney stack the mix should be a little stronger as the weather erosion is greater so follow the mix guidelines on the link above to our mortar mixes project. The video at teh base of this page shows the correct proportions of soft to sharp sand and the mix used on the wall is a top quality strength mix which will protect most external walls very well. The sharp sand is added to reduce the flexibility of the render and to give it greater strength against both cracking, shrinkage and erosion. Soft sand contains more clay than sharp sand and is a lot more flexible. The sharp or coarse sand is a lot grittier than soft sand or builders sand. As such the mix needs to be strong and wherever possible, this strength is increased by adding some sharp sand (or grit) to the mix. Generally speaking, the render you are applying is there to form a solid, strong, waterproof surface to cover the layer below, be that brick, block, stone or even old render. Also remember to clean your tools thoroughly after and between usage. Your equipment, including mixer, water, soft sand, sharp sand and cement should be as close to the work as possible to save on time running backwards and forwards. Getting the Correct Mix for Your RenderДЇor detailed information on how to correctly mix your mortar see our project on Mortar Mixes. A little forethought here could be handy so think about fixing a tarpaulin or strong polythene sheeting to the top of the wall you are working on so if the rain does come down you can simply drop the protection to keep it dry.

Try to make sure you have a couple of fine days to do the job in вЂ“ if it rains too soon after you apply the render, it will be washed off the wall. Unless the wall has been recently built, you will need to clean it well вЂ“ remove any loose paint, and dust or loose debris, plants growing up it, scrub off any mould with a bleach, or fungicide solution, and hose down the wall to remove any dust and dirt that could stop the render from adhering.ДЄfter washing down It will be Okay to render the wall if it is still damp but do not try and render while it is still running with water. We donвЂ™t advise you to start on rendering house walls without some experience, but thereвЂ™s no reason why you shouldnвЂ™t have a go at a garden or garage wall to start with. Like plastering, rendering is a job that requires some skill and plenty of practice.
