I appeal to the management of the Zabudov enterprise. It's clear that your company's products are in great demand now, but is there any way to take your site more seriously? It's your face after all. It is not clear where to look for information about the product!! The instructions are hidden in the basement of the site!!
1. Go to the site yourself, for example, to the "Tile" section, imagine that you are an ordinary buyer, and try to figure it out.
2. Why is it not possible to write instructions for use immediately to the product information? How can an ordinary person understand where the instructions for using Glue for blocks are located?
3. Go to the section "Building mixes" https://zabudova.by/catalog/sukhie-stroitelnye-smesi / and read what it says. Who wrote this? What did he write about? Nothing is clear.
It is a pity that our manufacturers are so negligent about their business!!!
If this is a market, then either the seller is in the workplace, or make room for another. Don't ask any questions (politely and not very much) until the buyer wants to ask.
