Re: fiberglass textured deck repair questions
There are a number of options here.
You can get rubber glue-down panels in various patterns and colours that can to a decent job, but they do age and breakdown over time, and are not inexpensive. (Trade name Treadmaster)
Applying nonskid texture can be done with thickened 2-part paint that 'pulls' up like whipped cream when rolled and then hardens. This can be very aggressive nonskid but hard on bare knees etc.
Interlux markets a nonskid paint that goes on quite easily and has good nonskid properties at a good price (Interdeck).. it does like to hold onto dirt, though.
Probably the most popular choice for DIY these days is "Kiwigrip" - lots of people happy with the results with this product.
Finally you can simply add grit (sand, walnut shell, rubber bits like Awlgrip's Griptex, whatever) to virtually any paint. Some stir it in, others 'sprinkle' it onto a wet coat like a salt shaker and then lay on another coat for uniformity of colour. Getting a uniform attractive job with this method can be tough..
From the stuff we see here on this and other sites, it looks like KiwiGrip is the ticket.
