Pendi yengarava inodzivirira kusvibiswa ipende yakakosha inoiswa pamusoro pengarava. Chinangwa chayo ndechekuderedza kunamira kwezvisikwa zvemugungwa, kuderedza kuramba kukweshana, kuderedza kushandiswa kwemafuta engarava, uye kuwedzera hupenyu hwebasa rengarava.
Nheyo yependi yengarava inodzivirira kusvibisa ndeyekuvaka chimiro chakakosha pamusoro nekuwedzera zvinhu zvakakosha zvinodzivirira kunamatira uye zvinhu zvine simba shoma pamusoro, nokudaro zvichideredza kunamira kwealgae, shellfish nezvimwe zvipenyu zvemugungwa. Nzvimbo iyi isingatsvedzerere, yakatsetseka inogona kuderedza kuramba kwemvura uye kuderedza kukweshana, nokudaro ichizadzisa mhedzisiro yekuchengetedza simba uye kuderedza kusvibiswa. Pamusoro pezvo, pendi yengarava inodzivirira kusvibisa inogonawo kuchengetedza ganda uye kuwedzera hupenyu hwayo hwekushanda.
Pendi yengarava inodzivirira kusvibiswa inowanzo kamurwa kuita mhando mbiri: inova silicone-based uye inova fluorocarbon. Pendi yengarava inodzivirira kusvibiswa inoshandisa silicone resin nezvimwe zvinhu kugadzira nzvimbo isinganyungudike zvakanyanya kudzivirira kunamira kwezvipenyu uye ine simba rakanaka rekudzivirira kusvibiswa; pendi yengarava inodzivirira kusvibiswa inoshandisa fluorocarbons kugadzira nzvimbo isina simba rakawanda, zvichiita kuti zviome kuti zvipenyu zvinamire uye ine simba rekudzivirira kusvibiswa kwenguva refu.
Mhando dzakasiyana dzependi yengarava inodzivirira kusvibiswa dzinogona kusarudzwa zvichienderana nenzvimbo inoshandiswa nengarava uye zvinodiwa zvinotarisirwa. Kazhinji, pendi yengarava inodzivirira kusvibiswa inochinja hunhu hwepamusoro peganda, ichideredza kunamira kwezvisikwa zvemugungwa uye kuramba kuyerera kwemvura, nokudaro ichizadzisa chinangwa chekuchengetedza simba, kuderedza kusvibiswa uye kuwedzera hupenyu hwebasa reganda. Inokosha zvikuru mukuchengetedzwa kwezvakatipoteredza zvemugungwa uye kushanda kwehupfumi hwengarava.
