1. MORTAR AND MICRO-CONCRETE ADDITIVE

 1.1 Adherence bridge

Before applying the mortar or micro-concrete, it is necessary to make the adherence bridge between the substrate and the product to be applied. For this application, it is necessary to follow the application instructions below.

STEP 1: The surface that will receive the mortar and/or micro-concrete should be free from grease, oil, and be clean.

STEP 2: Apply the adherence bridge according to the ratio below:

1 part of Hard Defense Max| 3 parts of water | 1 part of cement | 2 parts of sand. 

Application suggestion: The adherence bridge needs to be always wet to have the sub-floor or micro-concrete, then, if the application is in a very large area, prepare the liquid products mix (HARD-DEFENSE MAX and water) separately from the solids (cement and sand.  

STEP 3: Launch 0.5 liters/m² of the liquid components mix on the surface; then launch 0.5 liters/m² of the solid components mix and sweep it to make the products mix.

 Then, apply the sub-floor or micro-concrete, always wet on wet.

1.2 Ratio suggestion – SUB-FLOOR

CEMENT AND SAND MORTAR

The ration suggested below has a yield of 12m² with thickness of 1 cm.

Consumption of HARD-DEFENSE MAX is 0.83kg/m² to each thickness of 1 cm.

1 sack (50 kg) of Portland cement
6 cans of medium sand
10 kg/liters of acrylic resin HARD-DEFENSE MAX
Water as required (ideal factor 0.7 A/C)

1.3 Ratio suggestion – MICRO-CONCRETE

For high-resistance industrial floors and with thickness higher than 10 mm, use the ratio for micro-concrete.

The ration suggested will have a yield of 15m² with thickness of 1 cm.

1 can of Portland cement ¹;
2 cans of medium sand;
2 cans of grit or crushed stone (load) ²;

0.5 can of fine sand;

3.6 kg/liters of acrylic resin HARD-DEFENSE MAX;

Water as required (ideal factor 0.6 A/C).

¹  For locations that need resistance to chemical attack pH > 3,5 – such as: Cold stores, Sugar and Alcohol Industry, Dairy products, S.T.S. and T.C. (containment tanks) use Aluminum cement. Solutions for locations with temperatures from -15°C to 100°C.

²  Load with size of 1/3 of the floor thickness, (E.g. Floor with thickness of 15 mm, loads with diameter up to 5 mm should  be used).
