Definitions
PrimerLiquid or paste applied onto a substrate to obtain optimum bonding. It helps regulate the porosity of the substrate (reduce absorption, therefore adhesive usage), increase adhesion to non porous surfaces, improves application properties of later on applied adhesive
Tiling
Working timeTime between end of waiting time and moment when the application is no longer possible

Uses

NOVAFLEX 330 is a two-component solvent-free polyurethane resin especially designed for flooring application.

NOVAFLEX 330 is suitable for laying medium-thick bed flooring (2mm) in shops, offices, technical areas, pedestrian areas, halls and showrooms, restaurants and hospitals, etc.

Solvent-free
Ready to use self-smoothing coating
Excellent mechanical, wear- and impact-resistance
Flexible coating
Has excellent adhesion to most substrates: concrete, wood, tar, ceramic tiles and metal
European fire classiciation : Bfl-S1

Safety:

IMPORTANT: before embarking on any work involving NOVAFLEX 330 the separate Product Safety Data Sheet must be studied carefully by those carrying out the work.

PREVENT skin and eye contact. Do not breathe vapours. Use protective gloves when mixing or using. Wear protective clothes and safety glasses.

Shelf life:

Up to 1 year in the original, unopened containers, stored in a dry place at +10°C and +25°C

Application

Application conditions

Working temperature: + 10° to + 30°C

Relative humidity: 70%

During application and cure, substrate temperature must always be at least 3°C above the dew point temperature.

PREPARATION

Preparation should be in accordance with building standards. Concrete subfloors must be clean, sound, dry (relative humidity <4%), of adequate compressive and tensile strength (at least 25 MPa and 1,5 MPa respectively after 28 days cure for new concrete) and not subject to hydrostatic pressure. They must be free from laitance, cracks and structural defects; clean and free from dust, grease, curing compounds, sealers or any other contaminants that would inhibit proper bond. Depending on subfloor condition and type, subfloors are treated by grit blasting, mechanical planing, scabbing, sandblasting, high pressure water washing or chemical stripping. After mechanical treatment of a subfloor, thoroughly vacuum all dust.

Steel and metal decking should be grit blasted, grinded or sand blasted, then degreased with MEK (Methyl Ethyl Ketone). Prime metal surface with EPONAL 348, after curing sand and degrease it with MEK just before over-coating.

APPLICATION OF NOVAFLEX 330

Primer

Using a roller or a squeegee, apply a coat of EPONAL 321 or EPONAL 376 for damp substrates not subject to water seepage or substrates likely to suffer from rising damp, at a rate of 300-400 g/m² depending on roughness, porosity and temperature of the substrate.

APPLYING NOVAFLEX 330

Slowly add the hardener into resin (part A + B) while mixing, mix thoroughly for 3 to 5 minutes with an electric drill and mixing paddle (speed: not more than 300 rpm in order to avoid air bubbles formation).

Apply immediately the mixture using a notched trowel, float or adjustable rake. Use a spiked aeration roller to improve surface finish and to avoid bubbles inclusion.

NOVAFLEX 330 must be applied in a single coat onto a dry coat of EPONAL 321 or EPONAL 376 primer.

Between each coat a minimum drying time should be observed depending on temperature:

Temperatures	+10°C	+20°C	+25°C
EPONAL 321	48 hours	24 hours	12 hours
EPONAL 376	48 hours	24 hours	12 hours
Set to foot traffic after:	4 days	48 hours	24 hours

IMPORTANT: Long exposure to sunlight/UV rays may cause variations in colours. This effect is more or less noticeable depending on initial colour. It does not alter mechanical properties of the flooring.
