LARSEN EU PRIMER – DIRECTIONS FOR USE:
PREPARATION
All substrates must be suitable for the intended application as per current good working practices. Surfaces must be dry and free from dust or any contamination which may interfere with adhesion. Ideally suitable mechanical methods should be used, e.g. enclosed shot-blasting, grinding, etc, to provide a clean, stable, open-textured surface.
MIXING
Pour total Hardener B into Base A container and drain thoroughly. Mix thoroughly by mechanical means, i.e. by use of electric drill with a slow speed stirring head. Ensure that the mixing is thorough. Never split or proportion packs of Larsen EU Primer.
LARSEN EU PRIMER – APPLICATION
Some systems require a wet on wet application onto EU Primer; otherwise EU Primer is used to provide a mechanical key. Consult the relevant technical datasheet or contact our technical department for further advice.
- WET ON WET APPLICATION – apply the mixed Larsen EU Primer uniformly to the surface by roller or squeegee. Do not allow to puddle. Apply subsequent product while the EU primer is still tacky – typically within 2 hrs @ 20°C.
- MECHANICAL KEY – apply the mixed EU Primer uniformly to the surface by roller or squeegee. Do not allow topuddle. Fully broadcast the primer with clean, kiln-dried 0.6 – 1.2mm sand at a typical rate of 2kg/m2. Allow to cure (typically 12 hours) then brush or vacuum off the excess sand to leave a sandpaper-like finish. Ensure no ‘bald’ patches remain. Subsequent coatings may then be applied.
- AS SEALER – apply the mixed EU Primer uniformly to the surface by roller or squeegee. Do not allow to puddle. Allow a minimum of 24hrs before trafficking.
CLEANING
Clean tools, etc. with Larsolve Thinners or similar before Larsen EU Primer hardens.
RESTRICTIONS
All work should be carried out using current best practice. Rate of cure will be affected by ambient and substrate temperature. Curing will be slower at low temperatures and faster at higher temperatures. All external work should be protected from moisture until cured or over-coated. EU Primer may ‘yellow’ when used as a sealer externally.
STORAGE
Free from extremes of temperature. Crystallisation may occur when stored at low temperatures. Should this occur, store in a warm place until crystals dissolve before using.
