Fire Retardant Spray for Upholstery

Fire retardant spray for upholstery, 3-2-1 Standard, and 3-2-1 Washable are clear, sprays for upholstery, card, paper, cloth, carpet, and mattresses. Importantly, safe to use tested on children’s bedding. Treated items can be dry cleaned and remain fireproof. Additionally, items treated with 3-2-1W, wash up to eight times before needing re-treatment. Furthermore is suitable for real and artificial Christmas trees to protect them from fire. Ideal for preventing rapid spread of flame on a range of upholstery, paper-based materials, and also soft furnishings.

Firstly, test on a small area to ensure compatibility with the material and dyes. When spraying onto materials such as curtains, cardboard, etc, use just a fine spray to dampen the material. Give polyurethane furniture a fine spray on the outer cloth and press it into the polyurethane with your hands or a clean cloth such as a handkerchief, then spray over the outer covering material with a fine spray of 3-2-1W.

For flame retardant sprays for synthetics, see Product 67 3-2-1 Special.

Application Instructions

First, spray a small sample of the material to ensure it is colour fast.

FURNITURE: Spray all the areas, which have foam underneath the material, so the material is
absorbing the 321 liquid.
Place the chair or settee on its back & spray all the underside material.
Place the furniture upright, spray the back, sides & front of the furniture, ensuring that the
material is wet with 321 liquid.
Should the seat cushions be removable, spray all material under seat cushions, ensuring that
you get 321 down the gaps.
Should the seat cushions have a zip fastener, then unzip & spray 321 over the internal sponge
material & all over the outer material, ensuring by pressing in with fingers, so that the sponge /
polyurethane absorbs the 321.
Re-spray areas such as the backs & arms of chairs, which have sponge foam underneath the
material, & using fingers, pad or cloth, press the 321 through the material into the sponge.
This procedure should also be carried out on the cushions that cannot be unzipped. Ensure
that these sponge areas are well soaked. (Note – If the material is 60% polyester, do ensure
that the foam areas are very well soaked). See below for leather & rexine covered furniture.

CURTAINS: If it is a single material & not lined curtains, spray while hanging, until the material
is moist. Spraying only needs to be carried out on one side. For lined curtains, then both
sides of the curtain must be sprayed. Apply to both sides equally for lined curtains.

CARPETS: Carpets can be sprayed while laid, if foam backed, then with a cloth or pad press
into the carpet as you spray, to ensure that the 321 is absorbed into the backing.

BEDDING, MATTRESSES: If it is possible, take off the cover of the mattress, then spray into
the foam; pressing 321 into the foam material with a cloth pad, ensuring that the foam absorbs
all the 321 thoroughly, then spray the cover until it is completely wet. Should the cover not be
removable, the spray over the cover, pressing the 321 into the foam until you feel it is totally

SHEETS, BLANKETS, COVERS, ETC: These can be sprayed with 321/W & washed
approximately five times, then re-treat by either re-spraying or dipping into the 321. Wring out
into a bowl & replace residue into the bottle for when re-treatment is necessary.

LEATHER & REXINE FURNITURE: With this type of covered furniture, the only way to treat
the foam is to tip the chair on its back, take off the underneath material & spray 321 up inside
the foam. With your fingers, ensure that the 321 is getting thoroughly absorbed into the foam.
For added safety in your kitchen, soak a tea towel in 321 & leave it near the cooking area, so
that if you have a pan fire, the tea towel can be placed over to help put out the fire.
Guide to the amount of 321 required for curtains, bed covering, etc., 6-10 m² per litre. Foam
filled furniture, approximately 5-7 m² per litre, according to the amount of polyurethane foam
