GENERAL NOTES - WALL COVERINGS

1.A wall covering specification is INCOMPLETE unless the specifier states specifically the TYPE and the OZ. WEIGHT per lineal yard (and/or metric equivalent).

(Please note that this is necessary to ensure bidding equality. For example, within one type range, cost variations MAY be as much as 50%!!!)

2.For consistency, the manufacturer's suggested weight criteria of OZ.S per LINEAL YARD (and/or metric equivalent) will be used throughout.

3.If material is from a different run, it should be pointed out that color and textures may vary, to some extent, from the submitted sample (sample book) or original supplied sample.

4.The following figures are minimum totals (including the backing weight plus the vinyl weight), and intended weight uses:

TYPE I - LIGHT TO MEDIUM DUTY12 oz to 19 oz per lineal yard

A maintenance free covering suitable for ceiling and wall areas with light to average traffic conditions.

TYPE II - MEDIUM TO HEAVY DUTY20 oz to 28 oz per lineal yard

The heavier fabric backing and vinyl film provides greater resistance to wear. Suitable for general applications.

TYPE III - HEAVY DUTY33 oz + per lineal yard

Recommended for maximum wear areas.

The Wall Covering Contractor shall check the material after 3 drops. If flaws in the material are detected, work shall stop and the wall covering supplier notified so that appropriate replacement material may be obtained without delay.

CLEANING OF VINYL WALL COVERINGS

1.Ordinary Dirt

Warm water and mild soap will remove superficial dust and dirt. A soft bristle brush is recommended for more stubborn areas and for heavily embossed vinyls.

Most non-abrasive liquid and non-abrasive household detergents are safe and effective. In all cases, vinyl must be rinsed with a damp cloth and clean water to remove any residue.

Isopropyl alcohol or naphtha may be used. Other solvents are not recommended unless tested on vinyl before cleaning.

2.Paint, Shoe Polish, Heel Marks

Wipe with clean cloth dampened with isopropyl alcohol, naphtha or kerosene. Do not spread the soil or cleaning agent to unaffected areas.

3.Tars, Asphalt

Immediate cleaning with cloth dampened with naphtha or kerosene.

4.Chewing Gum

Scrape off excess gum. Clean as for tars and asphalt, or place ice against chewing gum and break off gum as it hardens.

5.Lipstick, Ball-point Inks

Immediately remove with cloth and isopropyl alcohol. The longer the contamination remains on the surface, the more difficult its removal.

Chloride of lime treatment is effective in many cases. However, it is not warranted due to variations in the ingredients and in the inks or lipsticks.
