1.Application: It is suitable for the construction of substrates, such as the construction of concrete, marble, steel plate, etc. After the construction completed, it can present the marble pattern effect.

 It can be used indoor and outdoor, with mild concave-convex effect (see model effect).
2.Preparation before construction
(1)Before construction, Please checking the condition of the concrete base surface on site to ensure that the maintain time of concrete  is longer than 4               weeks, and the moisture content is below 8%.
(2)Construction tools (grinder, vacuum cleaner, mixer, electronic scale,trowel, long-handled cleaning brush (or rubber push plate), defoaming roller,                     spikes, trowel, short hair or sponge roller, etc.).

Note:
(1)There are many types of colorful floor materials (PV400, PV100 and HA6463), and the application effect is similar.
(2)If the quality of the selected rock chips is poor, and there is a problem of warping. it should be shoveled, cleaned up, and recoated with PV400 varnish           again after the completion of process 5.
4.Processing description
 1   
Surface
cleaning
It must be confirmed that the maintain time of concret is longer than 4 weeks, and the moisture content is below 8%. The surface’s hardness should be normal, and there is no hollowing or serious sanding. If the local moisture content exceeds the standard, it must be dried completely to avoid the problem of falling off caused by poor adhesion.
After removing the soil, mud, and dirt on the base surface, useing a grinder to remove the floating ash and loose concrete surface completely.
 2 Primer Add components A and B and color paste in proportion,stir evenly, scrape first and then roll.The scraper can be plastic putty scraper or a rubber scraper, and the roller is medium wool solvent-resistant roller.Appropriate amount of thinner can be added to achieve good operatingperformance. The consumption is 0.3kg/m2. If the base surface needs to be covered, the amount of primer canbe increased appropriately.
 3 Intermediate
coating
(1):After the primer is cured, apply the intermediate coating in the same way as the primer. At the same time, sprinkle the colored rock chips, spread them all over, and curing for more than 2 hours until the solidification is completed and the rock fragments are firmly bonded.
(2): Remove unbonded rock fragments. First,use an industrial blower to collect incomplete bonded rock,  which can be reused; Then use a heavy iron spatula to shovel the unbonded or upright rock thoroughly, and then blow again to clean the rock chips up.
 4 Topcoat The construction method is the same as the primer. Special care should be taken to ensure that no coating ismissed. If the surface unevenness is too strong after one layer of construction and can not meet the design requirements, you can re-apply One more layer topcoat.
* Operational time (Temperature 25℃,70%RH):
Product name  Operational time 
PV100,PV400,HA6463             25min
Note:
After the materials are mixed,the reaction is fast and the operation time is short.The construction must be fast to avoid the increase of material viscosity and construction problems.
5.Attention
(1)Polyaspartic materials need to be proportioned accurately.Please use an electronic scale to weigh accurately according to the proportion.
(2)If there are pigments used together, the addition amount can be more or less.Generally,it is recommended to be less than 30%, and the ratio of A,B
materials will not be affected.
(3)The mixing must be sufficiently uniform for 2-3 minutes.It is forbidden to buckle the barrel directly on the ground, which could cause poor local curing.
(4)High temperature and high humidity will accelerate the reaction of the material obviously.So be careful when constructing under high temperature and
high humidity environment. Starting with a small batch of samples and know the performance of the materials before large-scale construction.
(5)As the topcoat is varnish, it is easy to miss the construction.,Attention must be paid during construction and check carefully after construction,and ensure that the repair work is completed well.
