Butile: impermeabilizzare fori passanti coperta

[Horatio Nelson]

Ciao,
Sono quasi pronto! Butile acquistato ,è settimana prossima cominciò con il primo candeliere del mio 461. Mi sono letto tutto il 3D , e l'allegato articolo USA ( con tutti i limiti del mio inglese) ma non riesco a capire una cosa. Sia sea4see che l'americano spiegano che il serraggio delle viti/bulloni va fatto in un passaggio solo , ma poi a pagina due dell'articolo in inglese : ..."IMPORTANT...[] Tighten, let sit, tighten, let sit etc. etc.. When little to none squishes out & the bolt & nut become tight you can stop. This can take DAYS of small tightening events or weeks if you want to spread it out. It does not cure so do not rush it..If you have a wood deck core DO NOT crush it by over tightening, better yet bore out some core and pot the hole with thickened epoxy. Unlike the "two step" method you are not waiting for the butyl to "cure" or change consistency but you do need to allow it to slowly displace out from under the fitting. This compression & squeezing forces the butyl into every nook and cranny and makes for an excellent seal."...Ed ancora: ..."IMPORTANT I know I may sound like a broken record but people keep emailing me about this issue and the ONLY reason is because they did not fully read or comprehend TIGHTEN SLOWLY..DO NOT try and tighten the hardware to fully tight right away. Butyl relies on a slow compression to do it's job and seal properly. It takes TIME for it to compress, displace and move into every nook and cranny. The larger the deck fitting the MORE TIME it takes for this process to take place. Because of the density it takes time for it to get displaced and squished out the edges of the fitting. When it stops you can stop making small tightening adjustmensts."...Cos'è che non capisco?
