Question for those of you using Sealant as a preventative measure, what happens after it dries up? Do you just keep adding more every 3-6 months? Do you end up with a 400g tire after 3 or 4 applications?
30ml of Caffelatex liquid weighs approximately 36g. The dried weight of Caffelatex is roughly 25% (1/4) of its original liquid weight, which comes out to less than 9g of dried weight. So after 4 applications 36g of dried weight. This varies depending upon the tire you are using, as each tire seems to require slightly different amounts of sealant for maximum protection.
One application of liquid Caffelatex can last over a year in a tubular with a latex inner tube. Of course this depends upon all kinds of conditions and configurations; the kind of wheel and tire set-up, tire sidewall thickness and porosities, external temperature and humidity, bicycle storage conditions, etc... We recommend checking Caffelatex every 2 months, to make sure it's liquid and therefore retains its "puncture preventive" action.
In a thin walled tubeless setup the Caffelatex will last a much shorter time, maybe three months in hot conditions.
In a tubeless setup you could remove the tire and peel out the dried Caffelatex. However, any holes that have been patched by the Caffelatex could be re-opened.
Hope that helps.
