The importance of rendering
Another importance of rendering is in rendering the plaster. Yes, rendering is actually a two-stage process, and in order to have an attractive finish on your exterior walls, it’s important that you render all over the outside walls as well as inside them too!
Our procedure for rendering
The first step we take is to remove any loose rendering which is contributing to the cracking, and then we go about applying replacement rendering. We use a render mask to control where rendering goes on the surface so that it doesn’t get applied over areas you don’t want rendering, like windows or door frames.
We apply our material with an earthenware paintbrush in two coats (one coat for thicker materials).
After that, we leave the rendering to dry for at least two weeks before plastering.
Types of rendering
Acrylic render application
Oil render application
Water-repellant rendering systems
Tools we use for rendering and their uses
-Trowel for rendering onto a surface
-Brush for rendering on or between joints in brickwork
-Roller for rendering large areas of surfaces.
Other tools include a rendering knife, a rendering board, and an edger.
Plastic Render Float: this tool is used to create even layers when applying plastic renders over concrete foundations/rubble bases, e.g., LVF (lightweight expanded polystyrene). The design features two angled handles that enable the user to ‘float’ the material evenly without leaving any lines or marks where it has been applied before drying, hence its name; is also sometimes called “floaters”. It is used as a squeegee for rendering.
-Rendering Board-Used when rendering brickwork joints
-Edger-Use it around windows, doors, etc. as well as finalizing any edges that may have been created during rendering with other tools.
-Spade-Used for rendering on uneven surfaces or rendering from the top of a wall down
Speedskim. This tool is for rendering uneven surfaces.
-Corner Brush-Used for rendering around corners
-Filler pad (or “squeegee”)-Use this to apply rendering in place of a trowel, or as a more effective wet/dry method of rendering with the corner brush
-Damp sponge-For applying rendering where it has been applied with tools such as speed skim and corner brushes before drying; also ensures that there are no bubbles left in the render when dry by smoothing out any air pockets which may have formed beneath it during application.
Frequently Asked Questions
The average cost of rendering
How long do I wait for the render to dry before plastering?
Are there hazards in rendering?
Another hazard is the use of acids in rendering, but this is also greatly minimized by using gloves and eye protection.
