GYP-LOCK SEALER FOR GYPSUM CEMENT

Gypsum has been used in new construction floor underlayments for many years, mainly because it is economical, creates a sound barrier for apartments and condominiums, is fireproof, and most importantly has been effectively marketed throughout the construction industry.   

It is also widely known that the flooring industry in general are not happy with the performance of some gypsum floor underlayments.  Check out any number of forums on the internet to see first hand the problems floor installers are having and what they think.  When there is not a solid bond between the glue and the floor due to dusting, delamination of the flooring can occur.  In fact, it is not uncommon to rip up perfectly good flooring after 2 years of use because of delamination problems. A simple, inexpensive solution for this problem is using Gyp-Lock.

    

Here is a typical scenerio on a job site:  the Gypsum is poured and allowed to dry, then the plumbers, electricians, drywallers, painters, and numerous other trades people come in and do their work over a period of days and weeks.  They walk around and haul their equipment over the Gypsum, scratching and damaging the surface.  

As you know, Gypsum is very brittle and has very poor abrasion resistance, and any scratches or faults in the Gypsum will create dusting problems. The flooring guy comes back in (he's next to the last of the tradespeople to work on the project) and has to put a floor on top of the badly dusted, scratched and damaged Gypsum floor.  It's enough to give anyone nightmares.  

The only solution being offered in the industry now is to put a latex or acrylic on the Gypsum.  These products however, will leave a surface membrane, which interferes with the proper adhesion of glue down floor coverings, and can cause major delamination problems. Until now there has been no satisfactory solution for the flooring industry.  

Gyp-Lock Sealer was engineered and designed to work exclusively with the special chemical properties of Gypsum based cements.  Gyp-Lock penetrates the Gypsum and strengthens the top wear layer producing a hard, dust free and abrasion resistant surface that adhesive glues easily bond to. Gyp-Lock seals and strengthens, yet does not create a surface membrane that would interfere with bonding.  

The benefits of Gyp-Lock Sealer are not only important in the initial phase of floor installations, but are also important after years of wear and tear on the floor.  High traffic areas create abrasion and abrasion causes irreparable damage to the Gypsum below.   Literally Gypsum can turn to dust from years of foot traffic and this will subsequently causes major delamination problems for the flooring.
