If the ground has been cleaned with acid, be sure to neutralize the acid before use. The surface should be porous enough to absorb. The earlier it is used, the greater the compressive strength it produces. The surface requires cleanliness. Make sure that wax, grease, rubber, acrylic paint or other surface sealants are removed before use. In order to make the full penetration of the product into the concrete, it is necessary to carry out the surface shot blasting, scraping and peeling treatment. Construction methods can vary depending on time and volume of work:
A.1) steel trowel finish for general indoor industrial floor：
One run, about 16-23 square meters per gallon.
New construction on the ground can be followed in the pink operation, when people can walk on the above without producing footprints, can be applied. In general, the requirements of the new concrete floor for 7-28 days after curing the use of kentic concrete sealant treatment.
Drench the surface with CHEMTEC ONE and moisten it thoroughly, while gently brushing or mechanically scrubbing the floor until it becomes slippery and thick, a process that takes about 15-25 minutes. Use a rubber broom or vacuum cleaner to remove all surface stains and residue, then let the ground dry naturally. During the construction process to ensure that the ground can not become too early dry, do not touch the water, after the completion of construction within 12 hours to keep the ground dry and not frozen.
The surface of the old floor should be cleaned thoroughly before construction, and if necessary, it can be polished. Before the construction of the ground must be completely dry, construction process reference to the new system of ground construction methods, pay attention not to let the ground produce puddles.
After using CHEMTEC ONE for 1 month, it will produce a marble-like luster. The longer it is used, the better the effect will be.
After the maintenance of the ground after construction wait until the ground dry (generally in the completion of 3 hours) , you can use mechanical vehicles.
A.2) steel trowel finish for food processing areas, supermarkets, dusty old ground:
Two runs, about 14-18 square meters per gallon.
Drench the surface with CHEMTEC ONE and moisten it thoroughly, while gently brushing or mechanically scrubbing the floor until it becomes slippery and thick, a process that takes about 25-35 minutes. This time with a rubber broom or mechanical cleaning machine to clean the surface residue thoroughly, and then let the ground dry 30 minutes, continue the second construction, the same method as the first. Let the ground again dry 30 minutes, the second construction process to ensure that the ground does not become too early dry.
The surface of the old floor should be cleaned thoroughly before construction to ensure that moisture can permeate into the concrete naturally. Dry ground before construction, the specific construction method with the new ground, pay attention not to let the ground produce puddles.
After construction, wait until the ground is dry (usually 3 hours after completion) , you can use mechanical vehicles.
B) Broom finish, applied to bridge deck, highway, parking, driveway construction twice, the amount of approximately 11-12 square meters per gallon.
Saturate the surface with CHEMTEC ONE so that it is thoroughly and evenly wet. Repeat on the prematurely dry surface, brushing the entire surface until it is smooth and thick, then wait for the surface to dry. The second construction will continue after 6 hours, the method is the same.
C) Construction of vertical walls or the underside of bridge decks or the top of parking lots
Because it violates the principle of gravity to work in these places, it slows down when it is needed and works two or three times. This time need to use roller brush or spray spray. Make sure the surface is completely dry before processing. In the vertical surface construction, to roll down from the top. Soak the product thoroughly on the surface, but not so much that it flows down. After the surface has been dried for 2 to 3 hours, the second and third construction is carried out. The construction method is the same as the first one. When working on the bottom of the bridge deck and the top of the parking lot, soak the surface until it starts to drip. Wait until the surface is completely dry, about 2 to 3 hours, the second and third times of construction. This kind of place usually requires three times of construction. Cement surface conditions, temperature and construction conditions will directly determine the amount used. Typically, use 16 to 23 square meters per gallon per serving.
After construction, wait until the ground is dry (usually 3 hours after completion) , you can use mechanical vehicles.
points to note：
1.Workers should take appropriate precautions before construction to avoid direct contact of CHEM TEC products with the skin. If accidentally splashed into the eyes, rinse with plenty of water. Store away from children. Do not swallow.
2.Keep the construction area well ventilated.
3.Keep the ground dry within 12 hours after construction.
Explanation：
1.This product is non-toxic, non-flammable and complies with all VOC regulations and USDA United States Department of Agriculture Food Regulations.
2.Different quality of the ground will affect the actual amount used.
