PVC floor coil drum problem is the most easily occurring problem in the construction and use of PVC flooring at present.
One, what the situation may be the floor problem - the perfect new PVC floor is laid on a flat, smooth, clean, dry ground (no scraping); the ambient temperature is kept at 20 - 38 C, the air relative humidity is not more than 75%; the time is more than 24 hours - what's the problem with the floor.
Two, paving the floor drum package, the reason is generally to look for ground foundation; the selection of auxiliary materials; the climate and temperature in the construction; construction process, details; use links and so on.
The foundation ground level prevention and dampproof did not do well; foundation ground leveling, hardened unqualified; ground-based Undry (water content > 3%); self leveling drum, self leveling, self leveling, bad glue, low temperature (temperature below 13 C), high humidity (> 75%), air drying time, flooring Exhaust is not in place, just paste on the welding (glue is not solidified), under the floor infiltration of water and so on.
Common problems one: the groundwork is not dry
The foundation surface is dry and moisture content is less than 3%. Otherwise, the self leveling and floor are likely to be bulging.
Common problem two: self leveling
Spread on the Internet: self leveling in general 24~48 hours to do well, you can carry out the PVC floor paving - this is not practical, irresponsible - self leveling must be dry (water content is less than 3%); self flow is not dry, PVC floor must be wrapped in the future.
Common problem three: self leveling ash serious
Because of basic ground problems, or self leveling quality problems, or construction link problems, or temperature, climate problems, and so on, there is a serious self leveling ash, which finally causes the PVC floor to not stick to the ground at all.
Common problem four: error selection error
Materials are very important in the construction of PVC floor - different technology, different specifications, different structure of PVC floor to the same material, different use places, different sites and environment, different seasons and climate, and other materials are different requirements - few people take this seriously.
For example, glue - the Chinese people now use a kind of glue called "sheet glue", which is called "fool glue" - the leader of the PVC flooring material field and the strict Germans "dare not"... It's called 'glue'.
Common problem five: low temperature
Paving PVC floor must guarantee a reasonable ambient temperature. Generally, the temperature is kept at 20 - 35 centigrade, and the construction must be carefully under 15 degrees centigrade; under 5 degrees, the construction is forbidden.
Common problem six: high air humidity
It is required that the relative humidity of air is between 20% and 75%, which is greater than 75% and is not suitable for paving PVC floor.
Common problem seven: the time of air curing is unreasonable
Different glue, different floor, different ground, different environment and so on - Air glue time is different - it needs the master's professional accomplishment, experience accumulation, responsibility, professional accomplishment and so on.
Common problem eight: exhaust is not in place
PVC exhaust after flooring needs timely, attentively, patience, exertion, meticulous, comprehensive and so on.
Common problem nine: not compacted
After the PVC floor adhesive, it is generally required to press the roller at least 50 hours in about 2 hours, and more effective measures must be taken in special circumstances.
Common problem ten: Welding prematurely
After the PVC glue is laid, it is generally required to weld again after 24 hours.
