Vysa-Bond Sealer / Primer for sub-floor preparation

Vysa-Bond Primer is a medium viscosity homopolymer emulsion of Vinyl Acetate supplied as a concentrate ready for dilution with water at 4:1 to produce an effective sealer / primer for use during floor preparation before installation of electric underfloor heating systems. Undiluted, Vysa-Bond Primer passes the BS 5270 Part 1: 1989 test requirements for adhesive bond strength.

Vysa-Cable Kits

Vysa-Bond Primer is provided as part of the Vysa-Cable Kit to enable the installer to seal / prime the sub-floor surface so that the self-adhesive tape, used to secure the cable runs in position, bonds to the floor surface. Unless the floor is sealed after sweeping, small dust particles remain to inhibit effective adhesion.

Vysa-Pron thermal insulation

Vysa-Bond Primer is provided with Vysa-Pron thermal insulation to enable the installer to seal / prime the exposed surface of the Vysa-Pron after it has been bonded to the sub-floor. Test have shown that bond strength of tile adhesive and latex floor smoothing compound is greatly improved if the Vysa-Pron surface is primed.

Vysa-Bond Primer may be used neat (i.e. undiluted) as an adhesive for Vysa-Pron thermal insulation.

For example, the 500 g bottle of Vysa-Bond Primer is usually sufficient when used neat to bond 3m2 ~ 4m2 of Vysa-Pron thermal insulation to the sub-floor with enough Vysa-Bond Primer left over to dilute (4:1) and use to prime the upper surface ready to accept the tile adhesive.

Preparation

Surfaces must be clean, dry and free from any contaminants liable to impair adhesion.

Bonding conditions

The sub-floor surface and ambient temperature should ideally be a minimum of 20°C and not less than 10°C when Vysa-Bond Primer is applied.

Method of application

Dilute 4 : 1 with clean water (4 water :1 Vysa-Bond Primer ), apply with the roller supplied or a brush and then allow to cure / dry. Wash brushes etc. thoroughly with clean water immediately after use.

Coverage

Vysa-Bond Primer is supplied in 500 g bottles and will typically cover about 12m2 when diluted – depending upon the porosity / absorbency of the sub-floor surface.

Ambient temperature and cure times

Vysa-Bond Primer is humidity and temperature dependent. The curing time also depends upon the porosity of the floor surface. Vysa-Bond Primer will usually cure in about 30 ~ 40 minutes at 20°C but could take longer at lower temperatures.

Do not use at ambient temperatures below 10°C.

Storage

Store Vysa-Bond Primer in cool dry conditions between +5°C and +30°C. Protect from frost.

HEALTH & SAFETY Vysa-Bond Primer does not create a health hazard and is safe in normal use. Always observe good personal hygiene practices. Ensure adequate ventilation if using in confined areas. Wear goggles where risk of splashing occurs. Splashes in the eye must be washed out immediately with clean water for at least 10 minutes, then seek medical attention. Wash splashes off skin with cold water before the PVA dries. Any dried resin can be removed with hot water or skin cleansers. Do not take internally.

Keep out of reach of children.
