V takov\u00fdch p\u0159\u00edpadech je tedy lep\u0161\u00ed vyu\u017e\u00edt jinou metodu.Jako vhodn\u00e9 se ukazuje zejm\u00e9na chemick\u00e9 kotven\u00ed, kter\u00e9 se vyu\u017e\u00edv\u00e1 p\u0159edev\u0161\u00edm u zateplen\u00ed. Prov\u00e1d\u00ed se za pomoci nejr\u016fzn\u011bj\u0161\u00edch lepidel, av\u0161ak v\u011bt\u0161ina lid\u00ed nem\u00e1 p\u0159\u00edli\u0161 p\u0159ehled o tom, jak cel\u00fd proces funguje, s v\u00fdjimkou toho, \u017ee se dan\u00fd objekt ke zdi zkr\u00e1tka \u201ep\u0159ilep\u00ed\u201c. To je v\u0161ak velmi zjednodu\u0161en\u00fd pohled.Ve skute\u010dnosti jde o vyvol\u00e1n\u00ed chemick\u00e9 reakce a vytvo\u0159en\u00ed siln\u00fdch kovalentn\u00edch vazeb mezi atomy fas\u00e1dy a atomy objektu, kter\u00fd k n\u00ed bude p\u0159ipevn\u011bn.

Naopak, v z\u00e1vislosti na tom, jak\u00fd typ a mno\u017estv\u00ed lepidla bylo pou\u017eito, se dan\u00fd objekt m\u016f\u017ee dokonce v podstat\u011b st\u00e1t sou\u010d\u00e1st\u00ed fas\u00e1dy, alespo\u0148 na \u010das.
