How do I use concrete sealing curing agents? Details of the use of concrete sealing curing agent
With the rise of the heat of concrete sealing curing agent and people's understanding of its quality performance, many enterprises and families have begun to use concrete sealing curing agent sealing curing ground to improve ground performance, but do not know how to use concrete sealing curing agent, for this problem, today's Chinese paint online small editor to share: concrete sealing curing agent how to use? Details of the use of concrete sealing curing agents.
Theoretically, the construction method of concrete sealing curing agent is very simple, three steps: ordinary concrete ground (plain) treatment, spraying concrete seal curing agent, grinding polishing. However, in practice, there are some details still need to pay attention to, this is summed up in the construction practice of
of
.
I. After the concrete sealing curing agent completely penetrates the ground, it is necessary to clean up the remaining concrete sealing curing agent
the method of using Sikafu concrete sealing curing agent is: after the treatment of the surface, with the sprinkler evenly sprinkled Sikafu concrete sealing agent on the surface of the ground, keep moist for 30 minutes, with the appropriate hardness of the long hair push brush back and forth to help absorb; When the foot feels slippery thick, spray the ground with water mist and push back and forth with a long hair push brush, so that the excess concrete sealing curing agent all inhaled; When the concrete sealing curing agent feels slippery and thickened again underfoot, rinse the entire surface thoroughly with water, push back and forth with a long brush to help the viscous material rise, and wipe the entire surface to remove all surface stains and residual concrete sealing curing agent. It should be noted that when the surface becomes slippery and thick again, after thoroughly cleaning the entire ground with clean water, the sewage and residual concrete sealing curing agent must be vacuumed thoroughly (Note: residual curing agent must be cleaned).
concrete sealing curing agent completely penetrates the ground, if you do not clean up the residual curing agent, the surface will be molded, the surface will be very difficult to deal with the white mark!
2. Some unsatisfactory phenomena of concrete sealing curing agent
Before using concrete sealing curing agent, shake the concrete sealing curing agent solution well and then pour it into the low pressure sprayer, and then evenly spray the Sikafu concrete sealing curing agent uniformly, we must keep the surface moist, local viscous solution with water moisture. If the ground is drying too fast within 20 minutes, the second concrete sealing curing agent should be reseeded in time.
the concrete sealing curing agent solution evenly with a hard brush or rubber scraper, the use of mechanical scrub machine is better.
generally at room temperature of 20 degrees C, there is a good air circulation state, 2-4 hours after the concrete sealing curing agent solution completely penetrates and drys. If white residue appears during the drying process, it should be scrubbed with water immediately.
If you need to quickly increase the gloss, with a high-speed grinder equipped with 50-2000 eye resin grinders (speed 1000RPM) for two-way dry polishing of the ground, if the need for mirror effect, the need to polish with animal hair pads. After polishing, the ground cannot be watered or frozen for 24 hours and heavy vehicles and equipment must not be installed for 7 days.
1, concrete sealing curing agent is not possible to completely seal the ground
the principle of concrete sealing curing agent is that the curing agent penetrates into the concrete pores, after a chemical reaction to form a gel to discharge part of the air in the concrete, but does not completely seal the concrete pores, so that Maintaining a "breathable" state, especially in wet environments such as basements, if the "breathable" state of the pores of the concrete is not guaranteed, the water vapor will cause the entire arch of the concrete to cause the shell to fall off, and destroying the breathable state of its pores will greatly reduce the life of the concrete. This is why the underground garage made epoxy flooring easy to peel the reason, because epoxy floor paint it is completely painted on the ground, the ground simply can not breathe freely, the phenomenon of anti-dprk, resulting in the peeling of the floor.
2, concrete seal curing agent can not change the flatness of the original ground
concrete seal curing agent is permeable ground material, it can not form any form of thickness on the surface, its flatness is done by grinding construction, if the concrete surface drop is very large, want to To achieve a good degree of flatness, then the depth of polishing will also increase, and may even find concrete flat layer completely polished off, so, to get the mirror effect, then the newly poured concrete flatness will have to reach the national concrete pouring standards, and the old concrete can only do regional "mirror" effect.
3, the amount of concrete sealing curing agent is not the more the better
concrete absorption concrete sealing curing agent is determined according to its pore size, penetration depth is determined according to the molecular size of the curing agent, the amount of too much will easily form a crystalline layer on the surface, so the amount is the best, which requires the experience of the site construction personnel, so when entering the site construction, the sample is very important.
