Quality Waterproof Liquid Made
Pyongyang, June 29 (KCNA) -- The newly developed paraffin polymer waterproof liquid has widely been used in construction of apartment buildings in Pyongyang.

The new invention, better than other kinds of waterproof liquid, fills gaps or holes on floor and wall in the first application and films them in the second.

When a plastered floor is brushed with the liquid, a film like vinyl chloride sheet is formed on it.

As it is strong in tensile and adhesive strength, tile setting is possible just after its application.

It, low in the production cost, gives no adverse effect to environment.

The waterproof liquid, made of locally available materials, has proved effective in construction.
