R Cubed Posted June 2, 2011 Share Posted June 2, 2011 Thought you might all need to take note Thompson's Water Seal has had a Formula change and is now NOT suitable for Canvas. It seems to have changed from spirit based to water based. Take note when buying..... Quote Link to comment Share on other sites More sharing options...
G506 Posted June 2, 2011 Share Posted June 2, 2011 Dammit! It used to be brilliant on canvas! Quote Link to comment Share on other sites More sharing options...
Tony B Posted June 2, 2011 Share Posted June 2, 2011 May not be a bad thing. Lots of other canvas waterproofers for animal rugs are waterbased. Quote Link to comment Share on other sites More sharing options...
R Cubed Posted June 2, 2011 Author Share Posted June 2, 2011 Maybe, but the local place I get it from advised me that it is now not suitable for canvas, now I do not know why but suspect it wont repel the water or might even damage the canvas, they have been told by their supplier and have put up a sign on the shelf by it !!!!!! Can anyone find out more info ? Quote Link to comment Share on other sites More sharing options...
Richard Farrant Posted June 2, 2011 Share Posted June 2, 2011 Just found this link to a forum which includes a reply from the makers saying it is not not suitable to use on artificial or manmade fibres.........well that surely does not include real canvas, does it? http://www.ybw.com/forums/archive/index.php/t-259461.html Quote Link to comment Share on other sites More sharing options...
ruxy Posted June 2, 2011 Share Posted June 2, 2011 http://www.thompsonsweatherproofing.co.uk/products/product.jsp?id=1 They still do the spirit based original. the "Ultra" is the Aqua EU Compliant water based.. Quote Link to comment Share on other sites More sharing options...

Apparently Oil Cloth was originally treated with linseed oil. Might be useful if you wish to 'paint' canvas as linseed oil was used as a paint base.

Richard Farrant Posted June 2, 2011 Share Posted June 2, 2011 No, real canvas is cotton. I know, and that was the point I was making. Going by a reply from Thompsons on that yachting forum I linked, they have altered the product and it should not be used with any manmade artificial or plastic type fabrics from now on. Similar statement on the data page that Ruxy linked as well. So if it is real cotton or flax canvas no problem still. That is the way I read it anyhow.

Tony B Posted June 3, 2011 Share Posted June 3, 2011 Easy way, I'll get some later today. Need it for another job, and try on a piece of scrap canvas. Quote Link to comment Share on other sites More sharing options...
Tony B Posted June 3, 2011 Share Posted June 3, 2011 Right , ventured into the local Hombase. There were two Thompsons water seal on display, the 'New Improved' and the Ultra. BOTH say do not use on Artifical or manmade fibres or natural rubber. (Though surley any artifical fibre is manmade?)There is available in aresol a Thompson fabric and leather proofer. So I'm going to send some scurrying electrons off to Thompson's and ask if the fabric proofer is available in larger tins. Quote Link to comment Share on other sites More sharing options...
Johnh Posted June 3, 2011 Share Posted June 3, 2011 Any body used the waterproofer on sale on Milweb (sold by Kerry Cheese) ? Quote Link to comment Share on other sites More sharing options...
Tony B Posted June 3, 2011 Share Posted June 3, 2011 Reply from Thompson's tech people. Thank you for your enquiry. However, the formula was changed on the Water Seal and the new formula is not suitable for use on any materials. It is only suitable for brickwork,stone work. I am sorry to say we no longer have a product suited to your requirements. I regret to be of little assistance on this occasion. Saddelery shops do sell waterproffer in bulk for canvas horse rugs.

ruxy Posted June 3, 2011 Share Posted June 3, 2011 BUT - in their Tech. Data Sheet as far as I know they never ever stated it was suitable as duck proofer. They sell treatments for brick walls !! They would not suggest suitable for anything outside their control.. I used to use Grangers Fabsil (fabricsilicon) on tents , then I joined a sailing club and was advised nobody used Fabsil for Lake District sunshine protection - everybody used Febsil (FEB Building Products , brick silicon sealer) , because it was the same stuff. I don't think it is in the FEB range now ? Everbuild Superseal - will be the same stuff (just had a perusal of the tech data sheet). I have used a few of this type of product on tentage duck and heavier type canvas - no problems. I have even sprayed tilts with cellulose OD paint - and it has never attacked the polyester stitching.. Quote Link to comment Share on other sites More sharing options...

Try this link here, especially the paragraph, "Fields of Application", mentions cotton, leather, etc. plainly. Obviously being dated 2008 this was for the older formula, but they still stated it. http://www.thompsonsweatherproofing.co.uk/datasheets/waterseal.pdf Quote Link to comment Share on other sites More sharing options...
ruxy Posted June 3, 2011 Share Posted June 3, 2011 That is the self & same tech. data sheet that as far as I can determine is on their present web-site ,, seems the person at Thompsons who answered the enquiry does not know what they are talking about. Two years ago I emailed Ronseal (Sherwin Williams) and asked if their metal paint (similar to ICI Hammerite) contained silicone oil - they said no.. A few weeks later they contacted me again and stated in fact that it did contain silicone oil. A bit too late as I had used it , quite high in silicone oil I would say but it seems to wash off the surface after about 1 year exposure..
