Ujeedadu waxay tahay in aan cidhif xidhid loo baahnayn, dushana waa UV la daweeyaa.

Inkastoo
Tayada alwaaxda bjørk waa mid aad u fiican, qiimuhuna waa mid aad qaali u ah, qiyaastii 400 oo loox kasta, laakiin waxay u egtahay mid wanaagsan.
Si toos ah ayaa loo isticmaali karaa in lagu sameeyo alaabta guriga iyada oo aan wax daaweyn ah la helin.

②Waxa aad u fiican in la xidho booska jikada iyo musqusha

③ Toosiye ayaa looga baahan yahay albaabka golaha sare

④ Looma baahna in loo isticmaalo alwaax badeed golaha wasiirada

⑤Kadib imaatinka, buraash buraash ama saliid alwaax si aad uga ilaaliso boodhka

Sida loo kala saaro tayada bjørk plywood badda.

①Marka la eego dhumucda maqaarka, guud ahaan waa qiyaastii 1.2mm, qaarna waa 0.3-0.5mm
