PRIMEBOND EPOXY is a 100% solids of pure epoxy resin and hardener. It is packed in separate containers identified as A for resin and B for hardener.
PRIMEBOND EPOXY is used to bond fresh concrete to existing concrete. It exhibits a high bond strength between concrete to concrete, between concrete to reinforcing steel, steel to steel and other materials. It comes in both low and medium viscocity depending on customer requirement
Prepare the surface where PRIMEBOND EPOXY is to be applied. Ensure that the surface is sound and dry, free from dust, loose materials, oil, grease and dirt. If old concrete is wet, moisture will rise through the concrete and it will fail to adhere.
Mix PRIMEBOND EPOXY by combining A and B at a ratio indicated on the label of the container. The quantity to be mixed should be just the right amount needed to cover that area to be bonded with the fresh concrete, so as not to waste the PRIMEBOND EPOXY. When excessive quantities are mixed, it will start to react. Reaction is indicated when the mix starts to feel warm and gelation will proceed. Once the mixture has reached the gelled stage, it will be rendered unusable. Thus, the correct timing of the mixing and placing has to be observed.
In mixing A and B, the mixing should be very, very thorough but avoid beating so as not to entrap and incorporate bubbles. The mixing should produce a uniform and homogeneous appearance. Then set aside undisturbed for 10 to 15 minutes. When the mixture starts to warm up, immediately brush on the surface of the prepared concrete.
After brushing the mixture on the surface, broadcast a little amount of dry sand. This will give the teeth to ensure a better grip. The fresh concrete may then be poured being careful that the epoxy coating has not gelled nor dried up yet. If it has dried up, then slightly abrade the surface and apply another coating. Broadcast a little sand again before pouring the fresh concrete.
PRIMEBOND EPOXY covers about 12-15 square meters per gallon set, depending on surface, or 1 gallon=.0038 cu-meter.
CLEANING OF TOOLS AND EQUIPMENT:
Tools and equipment should be cleaned immediately after use. If possible, use disposable tools. Hardened epoxy will have to be chiseled.
1. Work in a well-ventilated area.
2. Use safety goggles and gloves to avoid eye and skin contact.
3. Avoid scratching the face and avoid eating until hands are properly washed.
4. Solvents should not be used to remove epoxy from the skin. They tend to dry the skin and can cause dermatitis.
Gallon sets of part A and B. Total is about 3.8 liters
