As you can imagine there are thousands of questions to answer around rejuvenating canvas, and to be honest – I didn’t really know where to start when writing this. So I thought I would do it with a Q&A style composition.
Question: What do I use to waterproof my canvas?
Answer: There are a number of products that are available to use. In a nutshell I steer clear of any 100% heavy chemical or petroleum based waterproofing (as good as they are). I mainly stick to a water based concentrate product that is of course….. exceptional quality! Currently I am supporting the Stimex Brand. Stimex is a Dutch based company that is quite niche with the fact that waterproofing is their core business…. put simply – they are the best at what they do!
Question: How do I know if my canvas needs waterproofing?
Answer: Not to sound sarcastic…When it starts to leak! In short if it isn’t broke, don’t fix it.
Question: How often should I waterproof my canvas?
Answer: There are many varied answers to this question, so I will break them down into sections for you.
Question: How do I apply the waterproofing?
Answer: With a clean brush or sponge. (I recommend against anything that sprays due to the lack of obtaining even coverage.)
Instructions: (As per Stimex instructions)
Question: How much area does the waterproofing cover?
Answer: I am currently supplying the Stimex product and the 500ml bottle (water diluted concentrate) does approx. 20 square metres.
Question: How do I get rid of mould?
Answer: Available off the shelf here at Camping Country Australia is a product called Mould Rid. It is designed and formulated purely to remove mould and mildew from used canvas.
Question: How do I apply it?
Answer: Just like the waterproofing agent, it can be applied with a clean brush or sponge to both sides of fabric.
Instructions: (As per Mould Rid label)
Question: How much area does the Mould Rid cover?
Answer: I am currently supplying Mould Rid and it covers approx. 5 square metres a litre
Question: I have used the Mould Rid and there is still mould all over my canvas, why is that?
Answer: What you are seeing is the dye that has been left by the mould and mildew. This generally cannot be removed (unless in its infancy attaching stage) and is in the canvas for its life. (Do NOT scratch and wear away at the mould with a course brush, it will damage the canvas)
