Kui eesm\u00e4rk on hermeetik peale paigaldamist \u00fcle v\u00e4rvida, tasub lugeda allj\u00e4rgnevat, sest mitte iga toode ei ole selleks sobilik.<\/strong><\/p>\n<p><strong>Silikoonide&nbsp;<\/strong>puhul on asi selge ja konkreetne- need ei ole v\u00e4rvitavad. P\u00f5hjus peitub selles, et peale tardumist on nii happeliste kui neutraalsete silikoonide pind v\u00e4ga sile ja madala pinnaenergiaga, mist\u00f5ttu tavav\u00e4rvid nendega ei nakku. Seega tuleb kohe ostes valida sobiva v\u00e4rvusega toode, eriti kui kasutate neid kohas, kus silikoon j\u00e4\u00e4b p\u00e4rast paigaldamist n\u00e4htavale, n\u00e4iteks vannitoavuukides.<\/p>\n<p>Viimistlust\u00f6\u00f6del on levinud peamiselt&nbsp;<strong>akr\u00fc\u00fclhermeetikud<\/strong>. Need on elasto-plastsed vesialuselised tooted, mida kasutatakse enamasti v\u00e4ikese v\u00f5i m\u00f5\u00f5duka deformatsioonidega vuukides. Akr\u00fc\u00fcli on lihtne ja mugav paigaldada ning peale tardumist on see ka h\u00f5lpsasti v\u00e4rvitav erinevate v\u00e4rvit\u00fc\u00fcpidega, nt akr\u00fc\u00fcl- ja alk\u00fc\u00fcdv\u00e4rvidega. Akr\u00fc\u00fclhermeetiku tardumisel toimub vee eraldumise t\u00f5ttu alati teatav mahukahanemine. Seega tuleb parima l\u00f5pptulemuse saamiseks lasta tootel enne v\u00e4rvimist t\u00e4ielikult tarduda, vastasel juhul v\u00f5ib v\u00e4rvkate akr\u00fc\u00fcli pinnal praguneda. Akr\u00fc\u00fcli l\u00f5plik tardumine oleneb vuugi m\u00f5\u00f5tudest, \u00fcmbritsevast temperatuurist ja niiskustasemest. Kui v\u00e4hegi v\u00f5imalik, tuleks v\u00e4rvimist\u00f6id teostada j\u00e4rgmisel p\u00e4eval v\u00f5i minimaalselt 4-6 tundi p\u00e4rast akr\u00fc\u00fcli paigaldamist. Palju oleneb siinkohal ka v\u00e4rvi kvaliteedist, kiirema v\u00e4rvimise korral peaks kindlasti eelistama elastsemaid v\u00e4rve.<\/p>\n<p>Akr\u00fc\u00fclide tootearenduse tulemusena teevad j\u00e4rjest rohkem ilma n-n silikoniseeritud akr\u00fc\u00fclid, mille mehaanilised omadused- n\u00e4iteks elastsus, liikuvusv\u00f5ime, l\u00e4henevad silikoonidele. Seet\u00f5ttu kutsutakse silikoniseeritud akr\u00fc\u00fcle ka&nbsp;<strong>v\u00e4rvitavateks silikoonideks v\u00f5i maalrisilikoonideks<\/strong>. Oma olemuselt on siiski tegu vesialuselise tootega, mis tardub sarnaselt nagu tavaakr\u00fc\u00fclid ning on seega ka v\u00e4rvitavad.<\/p>\n<p><strong>H\u00fcbriid- ja pol\u00fcuretaanhermeetikud<\/strong>&nbsp;on v\u00e4rvitavuse seisukohalt sarnased- neid m\u00f5lemaid on v\u00f5imalik v\u00e4rvida vesialuseliste v\u00e4rvidega. Nende hermeetikute eeliseks v\u00f5rreldes akr\u00fc\u00fclidega on see, et tardumisel praktiliselt ei toimu mahukahanemist. Seega on nii h\u00fcbriid- kui ka pol\u00fcuretaanhermeetikuid v\u00f5imalik peaaegu kohe peale paigaldamist v\u00e4rvida. Oluline aspekt, mida ei tohi \u00e4ra unustada, on see, et h\u00fcbriid- ja pol\u00fcuretaanheremeetikuid kasutatakse oma omaduste t\u00f5ttu tihtipeale vuukides, milles esinevad suured deformatsioonid. N\u00e4iteks on t\u00e4nap\u00e4eval tavap\u00e4rane ootus, et fassaadihermeetik peab suutma kompenseerida deformatsioone \u00b125% ulatuses. Kui sellises kasutuskohas olevat vuugihermeetikut v\u00e4ikese elastsusega akr\u00fc\u00fclv\u00e4rviga viimistleda, siis varem v\u00f5i hiljem hakkab v\u00e4rvkate hermeetiku pinnal pragunema. Probleemi v\u00e4ltimiseks tasuks sellistes vuukides valida juba eos sobivat tooni h\u00fcbriid- v\u00f5i pol\u00fcuretaanhermeetik, mida pole tarvis \u00fcle v\u00e4rvida.<\/p>\n<p><strong>Millega arvestada hermeetikute v\u00e4rvimisel?<\/strong><\/p>\n<p>1.
