Application Instructions

Base Surface

Suitable base surfaces:

Steel

Cleaned and sanded, galvanized/electrolytically zinced sheet steel or soft aluminum Sanded factory primer (not on large areas of new parts that have been sanded and coated with KTL primer) Thoroughly sanded old primer or factory primer (excluding thermoplastic coating)

Surfaces prepared with two-part polyester products and then sanded very fine.

Note Because of the wide variety of alloys and manufacturing processes for metals, the base surface must first be tested to ensure that the pre-treatment provides sufficient adhesion.

Pre-treatment of base surfaces:

Carefully clean using Silicone Remover -LVM 020 000 A5- or Silicone Remover, Long -LVM 020 100 A5-.

Clean and sand factory or old paint, eliminate any potential rust areas, and sand transitions to old paint.

Use a suitable cleaning agent before reworking to ensure a clean and residue-free surface.

Processing

Dilutable with:

Two-Part Thinner -LVE 009 001 A5-

Two-Part Thinner, Plus -LHA 014 000 A5-

Two-Part Thinner, Special -LVM 009 200 A2/A5-

Two-Part Thinner, Long -LVM 009 300 A2- (for large objects and high temperatures)

Application type “coat”

Processing viscosity 4 mm for +20 °C, German Industry Standardization 53211 is the mixed viscosity.

Adding 50 % thinner at +20 °C material temperature.

Use a measuring stick to mix when pouring in the thinner.

Processing viscosity 4 mm gravity feed spraygun “Compliant” and “HVLP”:

DIN 4 mm: 18 to 20 seconds

ISO 4 mm: 36 to 45 seconds

Set spray nozzle (see manufacturer's information): “Compliant” and “HVLP” to 1.3 to 1.5 mm.
Set spray pressure (see manufacturer's information): “Compliant” to 2.0 to 2.5 bar.

Apply a coat when using as wash primer.
The prescribed layer thickness is 10 to 15 µm.

Note When insulating small, sanded through areas, use only water-based base paint or two-part HS top coat for the wet-in-wet and intermediate sanding processes on the One-Part Wash Primer -LVM 044 007 A2-/-LVM 044 171 A2-. Do not perform this action if the sanded-through area is not larger than 5.0 cm in diameter.

Ventilate at +20 °C room temperature, rework again after:

10 to 15 minutes with Two-Part HS Filler.

20 to 30 minutes with Water-Based Base Paint (for small sanded-through areas only) 10 to 15 minutes with Two-Part HS Top Coat (for small sanded-through areas only)

45 to 60 minutes to start sanding

Reworking

Use	Rework with
as wash primer	Two-Part HS Filler
as wash primer with intermediate sanding	Wet-sand with P 800-1000 grit sandpaper

Can be painted over with:

Water-based base paint and two-part HS clear coat (for small sanded-through areas only)

Two-part HS top coat (for small sanded-through areas only)

Caution

Do not rework with polyester products.

Do not apply to thermoplastic coatings.

Do not rework with epoxy products.

Do not rework with water-soluble products.

Do not dry-sand.
