Glass Fiber Reinforced Gypsum, known by its acronym GFRG, is used as an interior finishing material as an alternative to plaster. The material uses glass fibers held together with gypsum concrete. This combination can be cast into any shape, is flame-retardant, and lightweight. GFRG also offers additional strength over plaster. But while it is extremely durable, like all materials it should still be treated and maintained carefully to extend its look and lifespan.
As water and dust can damage GFRG, the material should be primed and painted as soon as possible after installation. This will provide a protective barrier against water and dirt, as well as making it easier to clean. GFRG that has been properly finished can be cleaned with standard cleaning materials.
If the GFRG requires cleaning before it has been finished, it should be pat dry afterwards. The water should not be allowed to dry on the GFRG.
Once the GFRG is primed and painted, it can be cleaned with basic supplies. Regular maintenance will lengthen the lifespan of the panel. To clean, you can use:
- Soft Sponge and Soap Solution – Diluted soap can be applied with a sponge to remove general dust and dirt. It should be rinsed with water.
- Fiber Brush and Gentle Cleaning Material – For more persistent dirt and stains, you should use an all-purpose cleaner and a fiber brush for cleaning. It is recommended to always test any cleaning solution on a small, inconspicuous area in case it reacts poorly with the GFRG.
The following cleaning methods are not recommended as they can scratch or deteriorate the gypsum in the panel:
- Strong chemical cleaners or acid cleaners
- Abrasive materials
- Scraping or cutting tools
It is possible to use a sharp razor to remove paint and adhesive materials if they do not come off with more gentle cleaning methods. The razor should be carefully and slowly slid between the material and GFRG surface with gentle pressure.
By following these guidelines, you can ensure GFRG panels resist dust and blemishes and can be cleaned without damaging the underlying material when necessary.
