How to use Zemcoat Original
1. Surface Preparation / Paghahanda sa pagpapahiran
Substrate must be structurally sound, clean & free from loose concrete, dirt, form oil & other contaminants. Prior to application, wet substrate well with clean water using a sponge or a roller brush. For outdoor application & during extreme hot weather conditions, such as noon time or summer, wet substrate very well and more frequently before applying skimcoat.
2. Mixing / Paghalo
In a clean non-absorptive pail (plastic or galvanized iron), mix clean water with Zemcoat. Mixture should attain a smooth, creamy & lump-free consistency. Use a mixing torque for best results. Mixing time: 2 – 3 minutes. Let mixture rest for 15 minutes. Mix again briefly before use.
Do not add additional water after final mix.
3. Application / Pagpapahid
While the substrate is still damp, apply Zemcoat to desired application thickness (2 – 5mm) using a steel trowel. Pot Life: 3 – 4 hours.
Setting time: 30 minutes. Curing time: 24 hours. If there is a need to increase the application thickness, apply a second coat just before the first coat is about to set.
TIP: Zemcoat has set when the finish looks matte. If needed, sprinkle a small amount of water when the surface is about to set, then smoothen to the desired finish.
