Druhy stierok<\/strong><\/h2>\n

Z\u00e1kladn\u00fdm rozdielom medzi stierkami je ich zlo\u017eenie. Na trhu s\u00fa dostupn\u00e9 nasleduj\u00face typy produktov:<\/p>\n

Sadrov\u00e9<\/strong> \u2013 ide o naj\u010dastej\u0161ie pou\u017e\u00edvan\u00fd typ stierok. S\u00fa ob\u013e\u00faben\u00e9 u vykon\u00e1vate\u013eov, preto\u017ee sa ve\u013emi \u013eahko nan\u00e1\u0161aj\u00fa. Okrem toho sa ich povrch d\u00e1 dlho upravova\u0165, \u010do u\u013eah\u010duje pr\u00e1cu. Pomocou nich je mo\u017en\u00e9 dosiahnu\u0165 dokonale hladk\u00fa stenu a strop.<\/p>\n

Cementov\u00e9 a cementovo-v\u00e1penn\u00e9<\/strong> \u2013 maj\u00fa hrub\u0161iu zrnitost ako sadrov\u00e9, preto nezabezpe\u010duj\u00fa tak hladk\u00fd povrch. Okrem toho s\u00fa n\u00e1ro\u010dnej\u0161ie na aplik\u00e1ciu. S\u00fa v\u0161ak odolnej\u0161ie vo\u010di vlhkosti a mechanick\u00fdm po\u0161kodeniam ako sadrov\u00e9 stierky.<\/p>\n

V\u00e1penn\u00e9 a sadrov\u00e9-v\u00e1penn\u00e9<\/strong> \u2013 ur\u010den\u00e9 na vyhladzovanie stien dokon\u010den\u00fdch v\u00e1penn\u00fdmi alebo sadrov\u00fdmi-v\u00e1penn\u00fdmi omietkami. Rovnako ako sadrov\u00e9 stierky by nemali by\u0165 pou\u017e\u00edvan\u00e9 v miestnostiach s vysokou vlhkos\u0165ou.<\/p>\n

Polym\u00e9rov\u00e9<\/strong> \u2013 s\u00fa \u013eah\u0161ie na aplik\u00e1ciu a spracovanie ako sadrov\u00e9 stierky. Umo\u017e\u0148uj\u00fa dosiahnu\u0165 ve\u013emi hladk\u00fd povrch. M\u00f4\u017eu sa pou\u017ei\u0165 na dokon\u010denie prie\u010dok v miestnostiach s vy\u0161\u0161ou vlhkos\u0165ou.<\/p>\n

Sadrov\u00e1 stierka<\/strong><\/h2>\n

Jej v\u00fdroba za\u010d\u00edna jemne mlet\u00fdm syntetick\u00fdm alebo pr\u00edrodn\u00fdm sadrou. Pr\u00edrodn\u00e1 sadra je ove\u013ea bielej\u0161ia a m\u00e1 dlh\u0161\u00ed \u010das tuhnutia. Na druhej strane, stierky zo syntetickej sadry maj\u00fa vlastnosti odolnej\u0161ie vo\u010di mechanick\u00fdm po\u0161kodeniam. Sadrov\u00e9 stierky by nemali by\u0165 aplikovan\u00e9 v miestnostiach s vysokou relat\u00edvnou vlhkos\u0165ou, napr. k\u00fape\u013ene, pr\u00e1\u010dovne, su\u0161iarne, chladn\u00e9 sklady. Sadrov\u00e9 stierky v\u010faka svojim vlastnostiam absorpcie vlhkosti m\u00f4\u017eu v t\u00fdchto miestnostiach odpad\u00e1va\u0165 od podkladu alebo praska\u0165. Je potrebn\u00e9 pam\u00e4ta\u0165, \u017ee sadrov\u00e1 stierka m\u00e1 schopnos\u0165 korodova\u0165 so \u017eelezom, preto musia by\u0165 \u017eelezn\u00e9 prvky izolovan\u00e9 od sadrovej stierky, aby nerezli. Po vyschnut\u00ed stierky je zvy\u010dajne potrebn\u00e9 ich prebr\u00fasi\u0165, tento proces je ve\u013emi pra\u0161n\u00fd a nepr\u00edjemn\u00fd. Na trhu existuj\u00fa stierky, ktor\u00e9 nie je potrebn\u00e9 br\u00fasi\u0165, nan\u00e1\u0161aj\u00fa sa na steny jednovrstvovo, presne zarovn\u00e1van\u00e9, hoci to vy\u017eaduje ve\u013ea sk\u00fasenost\u00ed a trpezlivosti.<\/p>\n

Existuj\u00fa aj biele stierky, vyroben\u00e9 z alabastrovej sadry, ktor\u00e1 im d\u00e1va mimoriadne bielu farbu. Pri ma\u013eovan\u00ed stien sa pou\u017e\u00edva menej bielej farby.<\/p>\n

Sadrov\u00e9 stierky sa pred\u00e1vaj\u00fa v vreciach ako such\u00e1 zmes. Pred pou\u017eit\u00edm ich treba zmie\u0161a\u0165 s primeran\u00fdm mno\u017estvom vody. Niektor\u00e9 produkty s\u00fa ur\u010den\u00e9 na kone\u010dn\u00e9 vyhladzovanie na mokro, \u010do v\u00fdrazne skracuje \u010das pr\u00e1ce a eliminuje br\u00fasenie na sucho \u2013 nepr\u00edjemn\u00e9 v\u010faka prachu.<\/p>\n

V\u00e1penn\u00e9 stierky<\/strong><\/h2>\n

Spojivom v\u00e1penn\u00fdch stierok je v\u00e1pno. Umo\u017e\u0148uj\u00fa dosiahnu\u0165 vrstvu s hr\u00fabkou nepresahuj\u00facou 5 mm. V\u00e1penn\u00e9 stierky sa m\u00f4\u017eu nan\u00e1\u0161a\u0165 ru\u010dne alebo strojovo. S\u00fa paropriepustn\u00e9 a maj\u00fa bielu farbu. Umo\u017e\u0148uj\u00fa dosiahnu\u0165 ve\u013emi hladk\u00fd povrch. S\u00fa \u013eahko spracovate\u013en\u00e9 a maj\u00fa dobr\u00fa pri\u013enavos\u0165 k podkladu. M\u00f4\u017eu sa pou\u017e\u00edva\u0165 v miestnostiach s vy\u0161\u0161ou vlhkos\u0165ou. Malo by sa s nimi pracova\u0165 na mokro, bez br\u00fasenia, ale br\u00fasenie je povolen\u00e9. Tieto stierky sa m\u00f4\u017eu nan\u00e1\u0161a\u0165 na v\u00e1penn\u00e9 omietky, cementovo-v\u00e1penn\u00e9 a bet\u00f3nov\u00e9 podklady. Nemali by sa pou\u017e\u00edva\u0165 na sadrov\u00e9 podklady. Jednou z v\u00fdhod v\u00e1penn\u00fdch stierok je v\u00e4\u010d\u0161ia odolnos\u0165 vo\u010di plesniam ako u ostatn\u00fdch produktov. Vysok\u00e1 paropriepustnos\u0165 tie\u017e zais\u0165uje komfortn\u00fd a zdrav\u00fd mikrokl\u00edmu v interi\u00e9roch.<\/p>\n

Cementov\u00e9 stierky<\/strong><\/h2>\n

Spojivom cementov\u00fdch alebo cementovo-v\u00e1penn\u00fdch stierok je cement. S\u00fa to tie\u017e such\u00e9 zmesi, ktor\u00e9 sa zmie\u0161aj\u00fa s vodou. Neumo\u017e\u0148uj\u00fa dosiahnu\u0165 tak hladk\u00fd a biely povrch ako sadrov\u00e9 stierky, ale maj\u00fa v\u00e4\u010d\u0161iu odolnos\u0165 proti po\u0161kodeniam. Nez\u00edskate s nimi tak hladk\u00fd a biely povrch ako po pou\u017eit\u00ed sadrov\u00fdch stierok. Ich ve\u013ekou v\u00fdhodou je v\u0161ak vysok\u00e1 mechanick\u00e1 pevnos\u0165 a mo\u017enos\u0165 pou\u017eitia aj v miestnostiach s vysokou vlhkos\u0165ou vzduchu. Steny upraven\u00e9 cementovou stierkou sa po jej vyschnut\u00ed nebr\u00fasia, tak\u017ee dom nebude zapr\u00e1\u0161en\u00fd. Na trhu s\u00fa tie\u017e biele cementov\u00e9 stierky. Nan\u00e1\u0161aj\u00fa sa v dvoch alebo troch vrstv\u00e1ch v z\u00e1vislosti od stavu podkladu. S\u00fa paropriepustn\u00e9. Cementov\u00e9 alebo cementovo-v\u00e1penn\u00e9 stierky sa m\u00f4\u017eu nan\u00e1\u0161a\u0165 ru\u010dne alebo strojovo. Ich hr\u00fabka po nanesen\u00ed je 1-3 mm.<\/p>\n

Polym\u00e9rov\u00e9 stierky<\/strong><\/h2>\n

Podobne ako v\u0161etky ostatn\u00e9 stierky maj\u00fa formu such\u00fdch zmes\u00ed na rozmie\u0161anie s vodou, ale n\u00e1jdete aj tak\u00e9, ktor\u00e9 s\u00fa pripraven\u00e9 na nan\u00e1\u0161anie, zabalen\u00e9 v plastov\u00fdch vedr\u00e1ch. Od sadrov\u00fdch a cementov\u00fdch stierok sa l\u00ed\u0161ia ove\u013ea v\u00e4\u010d\u0161ou flexibilitou. Je vhodn\u00e9 ich pou\u017e\u00edva\u0165 na tzv. n\u00e1ro\u010dn\u00e9 podklady \u2013 napr\u00edklad na sten\u00e1ch, ktor\u00e9 podliehaj\u00fa mal\u00fdm kon\u0161truk\u010dn\u00fdm pohybom. S\u00fa tie\u017e odoln\u00e9 vo\u010di vlhkosti. Polym\u00e9rov\u00e9 stierky vy\u017eaduj\u00fa br\u00fasenie, tak\u017ee prachu sa ned\u00e1 vyhn\u00fa\u0165. Polym\u00e9rov\u00e9 stierky sa m\u00f4\u017eu nan\u00e1\u0161a\u0165 ru\u010dne alebo strojovo. Ich hr\u00fabka po nanesen\u00ed je 1-3 mm.<\/p>\n","protected":false},"author":1,"featured_media":280347,"menu_order":0,"comment_status":"open","ping_status":"closed","template":"","categories":[875],"tags":[],"class_list":["post-278614","knowledgebase","type-knowledgebase","status-publish","has-post-thumbnail","hentry","category-baza-wiedzy-sk"],"_links":{"self":[{"href":"https:\/\/www.sanier.pl\/sk\/wp-json\/wp\/v2\/knowledgebase\/278614","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.sanier.pl\/sk\/wp-json\/wp\/v2\/knowledgebase"}],"about":[{"href":"https:\/\/www.sanier.pl\/sk\/wp-json\/wp\/v2\/types\/knowledgebase"}],"author":[{"embeddable":true,"href":"https:\/\/www.sanier.pl\/sk\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.sanier.pl\/sk\/wp-json\/wp\/v2\/comments?post=278614"}],"version-history":[{"count":0,"href":"https:\/\/www.sanier.pl\/sk\/wp-json\/wp\/v2\/knowledgebase\/278614\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.sanier.pl\/sk\/wp-json\/wp\/v2\/media\/280347"}],"wp:attachment":[{"href":"https:\/\/www.sanier.pl\/sk\/wp-json\/wp\/v2\/media?parent=278614"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.sanier.pl\/sk\/wp-json\/wp\/v2\/categories?post=278614"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.sanier.pl\/sk\/wp-json\/wp\/v2\/tags?post=278614"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
