Waiting time to overcoating

In normal conditions, Sikalastic®-487 can be recoated with another layer of Sikalastic®-487 after one night and within 2 days. In case of rain or if the recoating interval was exceeded, light abrasion and reactivate Sikalastic®- 487 with Sika Thinner C or for the best results remove the existing coating back to substrate and re-apply.

Drying time

24 hours for full cure.

 

SUBSTRATE PREPARATION

Surface must be clean, sound, smooth and dust-free as well as oil-free. A layer of diluted Sikalastic®-487 membrane (with 10% Thinner C) can be used as a primer for dry and contaminants-free concrete. In the case of high porosity, it is recommended to use an epoxy primer. Please see 'priming' section below for further information.

However, we are not responsible for the colour accuracy of the device you are viewing our swatches on. These variations arise due to different computer monitors and devices (make, model and technology, as well as resolution, contrast and brightness control settings) in much the same way a scan will differ from an original image and a colour photocopy. Furthermore, coatings can exhibit variation in perceived colour depending on gloss level and application method. If you require a very specific colour match, please make your selection via actual swatches and colour boards available at our showroom.
