Application method
ADMIX WP770 can be applied by brush or trowel. Surface preparation is very important. All surfaces should be sound, stable, clean and free from paint, oil, grease, contamination and dust. It may be applied to damp surface with no standing water. Hot, very dry or porous surfaces should be dampened with primer (for preparation of primer, dilute product with water in the ratio of 1 by 1).
Minimum two coats should be applied to give 770 microns of DFT in order to provide good protective layer. Although in aggressive areas such as Persian Gulf and southern islands, applying third coat is recommended. Where subsequent coats are to be applied, the first coat must be dry. If top screen or other constructional finishing should apply, blasting clean and sharp silica sand onto last layer (wet layer) is recommended to provide mechanical key.

Equipment carefulness
Tools and equipment should be washed with water and soap before drying. Cured materials can be removed mechanically and then be cleaned by paraffin or solvent.
