Working with Render
Select your question below
What Personal Protective Equipment (PPE) is required when handling cement based products?
Always wear the correct protective clothing when handling any product containing cement as it is an alkaline substance in a fine powder form:
- Gloves - to guard against skin irritation
- Face mask - to prevent dust inhalation
- Eye protection - to prevent dust from getting in to eyes
- Long pants and sleeves - to guard against skin irritation
- Safety boots - to prevent injuries to your feet when handling heavy items or using potentially hazardous tools
Always separately wash clothes that may be splashed with cement-based products at the end of each day.
How many days after application can I paint render?
It is important to follow the coating manufacturers’ directions for curing or drying times before painting.
The surface can generally be painted with water based paints after 14 days. For oil based paints being applied to a masonry surface, it is necessary to cure the surface for 5 days and then wait for 28 days before applying the paint.
Does paint need to be removed from a surface before I render it?
Yes. Before any cement based coating or render can be applied correct surface preparation of the substrate is essential. Any paint and residue from other coatings will prevent an effective bond and it is suggested that they be removed.
Why should a shovel not be used to measure concrete or mortar materials?
Cement is a dry product and is free flowing whereas damp sand tends to clump together. Cement tends to lie flat on the shovel and has less volume than the sand. Using a shovel does not ensure that materials are measured equally and it is recommended that proportions of raw materials are measured with a container such as a bucket.
Always use an accurate measure to add your water too as the most common mistake made when mixing concrete, render or mortar is to add to much water.
Too much water ruins the strength of concrete, mortar and render.
What is the coverage of one bag of Render It™?
One bag of Render It™ covers 2.5m2 at 5mm thickness.
Ensure that you mix the Render It™ with exactly 4 litres of clean water to achieve a workable mix. Only mix as much render as you can apply within 30 minutes. Discard any render not applied within 30 minutes and mix a fresh batch.
Can I mix Render It™ in my wheelbarrow?
Yes, simply add 4 litres of clean water and slowly add the Render It™ product mixing it thoroughly with a spade or shovel.
If multiple batches of render are required to complete your job, it is worthwhile considering using a heavy duty drill and stirring attachment to make mixing easier and more consistent across batches.
Can I colour Render It™ Multisurface with an oxide?
Yes, add one small jar of oxide per bag of Render It™. Be sure to accurately measure both the oxide and the water to reduce colour variation between batches. For lighter coloured pastel oxides be sure to use Cement Australia's Render It™ Multisurface Off White as your base product.
The Cement Australia range of oxides contains 10 contemporary colours.
Are there any limitations to the application of Render It™?
Cement Australia Render It™ Multisurface gives you all the convenience of a premixed product manufactured to trade standard with additives that allow you to apply this product in a one part system ranging in thicknesses from 2mm to 10mm in a single application.
Always plan to complete your rendering project in the early morning before the surface to be rendered is in full sun.
How do I use Render It™ to render a brick or block wall?
How do you cure freshly applied render?
Where render has been applied to a masonry surface, to prevent cracking it is vital keep the rendered surface moist for a period of time. Spray the surface with a hose on mist spray 24 hours after the wall is finished and repeat this for 5 days in the early morning and evening.
It is not advised to cure render that has been applied to blueboard or fibre cement sheeting.
