What is this anti slip material?

[sjclarkey]

Can anyone tell me what kind of anti slip material is on my boat. It is a collingwood. It definitely is not sand as it is very course like bits of metal. I need to deal with some rust spots which will have the result of giving a smooth surface and I would like to know what to sprinkle on top before the paint so I can match the surrounding anti slip areas. Otherwise it will look very patchy with different surfaces. Sand will look to fine. This stuff is all over the roof and decks. Many thanks for any ideas.

If the bumps are no painted sand/grit then by the size of them I would suggest Protektacote paint.

I thought that was the standard finish on Colingwood - just painting over the dust and swarf ?

 

 

This is the protectacote finish I had (but not yellow) Horrible stuff - holds all the muck / damp / slime despite scrubbing.

One of my worst boating decisions.

I agree I hate the finish. Very difficult to clean and maintain. Would never have it again!

Looks exactly like sand to me!!

I feels to large for sand to me. It’s has very sharp edges and feels like filings of metal?

Other anti slip grits are available e.g.

Thanks David the first one looks more like it!

The roof of our last shareboat was redone using crushed walnut shells. Very grippy but much coarser than sand.

 

Both the painted sand and the crushed walnut finishes were fairly easy to clean using diluted Aldi Caravan Cleaner and a stiff brush.

Look up m3 anti slip tape  we use it on buses 

what you have looks like it but painted over

If the grit is very angular it could be shot blast grit. Graham at Riversdale in Ireland uses this for non slip. It also has the advantage (or disadvantage) of normally being black.

Could be carborundum, its available in many grades and being inert and hard  does not soak water or wear away.

 

I use childrens' play sand sprinkled on wet paint and then overpainted.

I am going to try sugar one day, it has the advantage in that it can be dissolved and washed off to leave just the textured paint finish.

It looks like the carborundum grit we used on Python's deck counter and gunwales. it is much coarser than the sand type finishes and works really well, even if the treads of your boots are filled with mud!

Its a buggar on your knees though!
