Farang two dot zero Posted August 10, 2019 Share Posted August 10, 2019 (edited) I come back from Thai Watsadu shop and the salesman is heading me to a brand of Silicone sealant that I do not know. I doubt his impartiality so if someone would you have a good mark to advise me for white silicone no more than 200 bath for example TOA or 3M ?

eyecatcher Posted August 10, 2019 Share Posted August 10, 2019 Lots of silicones and sealants of different colours. Unless you told him what you need it for then his advice isnt worth a jot. So, to help you out, i will ask the question. Is it for: santaryware, glass,general external use, roofing, worktops, cracks. I currently have four 3m tubes, 2 bosny and 1 double D. Only got tge 3m because they were and always are 2 for 1.....200bt should be for two. Most important and i fell foul of this in a local merchant and global. Check the expiry date, if its not 12months hence put it back. I bought some 12 month expired and it was almost solid. Both stores received my full displeasure.

Popular Post canopy Posted August 11, 2019 Popular Post Share Posted August 11, 2019 The biggest mistake I see people make is they don't know there are two types of silicon: neutral and acidic. Acidic can corrode metal, stain paint and wood, and cause problems on other types of surfaces. All bottles of silicon at the hardware stores I have seen clearly state acidic/neutral in English so making the right choice is easy to do but the sales people don't tend to know anything about this very important attribute. 2 1 Link to comment Share on other sites More sharing options...

I bought some black recently, little less viscous and i suspect its not up to the same standard as real silicone, but time will tell 1 Link to comment Share on other sites More sharing options...

You need external quality mastic not silicone. It "should" have elastic qualities that allow expansion and contraction of the surrounding materials. Whatever is used however wil not last very long in the sun here. It will degrade in 18monthsand shrinkand fall away. 1 Link to comment Share on other sites More sharing options...

It will degrade in 18monthsand shrinkand fall away. Something that degrades in 18 months is probably acrylic, not silicone. Silicone has excellent outdoor durability and should last more than 20 years in the sun. When making a joint it is critical to use backerrod (pictured in green) and make an hourglass shape so the sealant can stretch rather than pull away from the sides. 3 Link to comment Share on other sites More sharing options...
