, according to netizen Mr. Yan, this spring just finished renovating the house, because of the urgent need for children, he is very high environmental requirements for paint. However, because he just bought a house, followed by decoration, which made him shy for a while, the expensive real paint far away, then at the suggestion of a friend to buy a brand of preferential promotion of sample paint.
Reporters visited a number of stores found that the sale of sample paint brand is not in the minority, many merchants also to upgrade the goods, shop decoration and other reasons for the sample paint promotion, preferential discount between 50% - 7 fold, it is very attractive.
merchants in the sale of sample paint will often be in the contract marked "sample promotion, no return" the words. Is it legal to do so? According to the paint merchants revealed that the warranty terms and years of the sample paint and new products are the same, but can not be returned
merchants explained: because the price of the sample paint itself is very low, and most of them are only one, so can not be exchanged, otherwise manufacturers will have to readjust the production line. When it comes to returns, merchants say that because they are sample coatings, they are not returned once they have been sold.
most merchants in the sale of sample paint are playing "low-cost" "environmental protection" and other propaganda, which is why it attracts consumer attention.
, is the reality really what the merchants advertise?
experts believe that the sample paint because has been placed in the store for a period of time, in the case of air circulation will evaporate some harmful gases, but in the case of formaldehyde, because of its slow release speed, so it takes a long period of volatility, so even if the sample paint placed for a period of time, it is impossible to fully release formaldehyde, consumers buy it home, still need to dry.
