Simiron Instant Patch, 100% Solids Polyurea Pourable Crack Filler, 1 Gallon Kit

Surface Preparation: Concrete should be a minimum of 28 days old. All dirt, oil, dust, paint, grease and other foreign materials must be removed to assure adhesion to concrete. For repair of spalled concrete or pop-outs, use a still wire brush or twisted wire wheel to remove any loose, unsound or deteriorated concrete before application. Cracks must be chased and cleaned with a diamond crack chasing blade on a handheld grinder. After preparing area, remove all dust and debris with a vacuum. All surfaces must be clean and dry before filling with Instant Patch.

Application:

1. Simiron Instant Patch has a mix ratio of 1 part Base to 1 part Activator by volume. Mix or shake both components separately before use.
2. Premeasure equal amounts of Base and Activator before mixing together. Mix Base and Activator by stir stick or paddle mixer for 20-30 seconds. Only mix enough material that can be used within 2-3 minutes after mixing.
3. Adding Silica Sand Be sure silica sand is dry and doesn’t contain any moisture before mixing with Instant Patch. For best application and usage premeasure Base, Activator and silica before mixing; do add more than one part silica to mixture. Add silica to base and premix together to ensure equal consistency. Premixing the silica into the base will make the mixing process easier when adding the activator and maximize working time. Add Activator to the pre-mixture of base and silica and mix for 20-30 seconds.
