How to Use LeTech Leather Primer

LeTech Leather Primer is applied after cleaning and surface preparation, but before applying Leather Colourant.

Correct preparation and application are essential for achieving strong adhesion and a durable leather finish.

Step 1 – Clean the Leather

Thoroughly clean the leather using LeTech Leather Ultimate Cleaner to remove surface dirt, body oils and other contaminants.

For heavily contaminated leather, particularly where grease or oils have penetrated the surface, use an appropriate LeTech Leather Degreaser.

Allow the leather to dry thoroughly before proceeding.

Step 2 – Prepare the Surface

Inspect the leather for damaged, loose or deteriorating coatings.

Where necessary, remove unstable finishing layers using LeTech Leather Prep or Leather Solvent Cleaner.

Once the surface has been prepared, remove remaining contamination using LeTech Leather Alcohol Cleaner or Leather Liquid Degreaser, as appropriate.

The leather must be clean, dry and free from contaminants that could interfere with adhesion.

Step 3 – Prepare Leather Primer

Shake or stir LeTech Leather Primer thoroughly before use.

For enhanced adhesion and coating performance, add 3% LeTech Cross Linker, depending on the substrate and application requirements.

Mix thoroughly to ensure the cross-linker is evenly distributed throughout the primer.

Only prepare the quantity required for immediate use.

Important: Once mixed with Cross Linker X, the prepared primer should be used within approximately three hours, according to the current product instructions.

Step 4 – Apply the First Coat

Apply a thin, even coat of Leather Primer using a suitable sponge.

Work the primer gently across the prepared surface, ensuring uniform coverage.

Dry the coating using controlled warm air from a suitable hairdryer.

Avoid overheating the leather or concentrating heat in one area.

Warm-air drying helps promote the reaction between the primer and cross-linker.

Step 5 – Apply Additional Coats

Apply further thin coats using a suitable airbrush or spray gun.

For even coverage, alternate the direction of application between coats.

For example:

• Apply the first spray coat using vertical passes.
• Apply the second coat using horizontal passes.
• Apply subsequent coats using diagonal passes where required.

Dry each coat thoroughly before applying the next.

Avoid excessive application, which may affect the flexibility and natural feel of the leather.

Step 6 – Apply Leather Colourant

Once the primer has dried sufficiently, proceed with LeTech Leather Colourant.

For best results, apply the colourant soon after priming, following the recommended application instructions.

Complete the restoration by applying a suitable LeTech Leather Top Coat to provide the final protective finish.

Cleaning Equipment

Clean application tools thoroughly with water immediately after use.

Where necessary, use an appropriate LeTech cleaning product to remove remaining coating residue.

Do not allow the primer to dry inside spray equipment.
