In normal conditions, Sikalastic®-777 can be recoated with another layer of Sikalastic®-777 after one night and within 2 days. In case of rain or if the recoating interval was exceeded, light abrasion and reactivate Sikalastic®-777 with Sika Thinner C or for the best results remove the existing coating back to substrate and re-apply.

Sikalastic®-777 can be subject to light foot traffic after 24 hours.

Surface must be clean, sound, smooth and dust-free as well as oil-free. In the case of a high porosity substrate, it is recommended to use an epoxy primer. Please see 'priming' section below for further information.

Reusable tools should be cleaned carefully with Sika Thinner C before curing.
