摘要:
A sealing method, comprising: introducing a moving stream of curable material into an opening; and curing a portion of the moving stream of curable material flowing back out of the opening to form a cured layer of curable material. The cured layer restricts or prevents at least a further portion of the curable material from flowing back out of the opening.
