Application Steps

MIXING

Premix Sikalastic® 748 PA Part A and Part B before combining. Add equal amounts of Part B to Part A while mixing using a mechanical mixer (Jiffy) at medium speed. Mix until a homogenous mixture and uniform color is obtained (typically 3 minutes) and mix frequently during application to maintain uniform color. Scrape the sides of the container to ensure that no unmixed material remains and use care not to whip air into the material as this may result in pinhole blisters or shortened pot life. Do not dilute under any circumstances.

APPLICATION

Apply at the recommended coverage rate and backroll using a 3/16" phenolic resin core roller or mohair roller .

Removal: Remove liquid coating immediately with dry cloth. Once cured, coating can only be removed by mechanical means.
