Overview

Overview

Back

Morrells White Acid-Catalyst Primer is a quick drying, opaque white acid-catalyst primer for spray application. Perfect for MDF and other wooden substrates. Offers excellent sanding properties and provides a suitable surface for subsequent over-coating with white Morrells Acid-Catalyst top coats or Morrells Fastmatch Acid-Catalyst Lacquer.

Preparation

Preparation

Back

Ensure that surfaces to be coated are clean, dry and free from any surface contaminates that may affect the final finish such as wax, oil or grease.

  1. Bare substrates should be prepared with 120 and 240 grit paper
  2. Ensure that all traces of sanding dust have been removed prior to application
  3. Inter coat sanding should be undertaken with 280 - 320 grit paper
  4. Take care not to sand through the primer

Application

Application

Back

Always do a small test area before starting any project to assess performance and end result. Follow the manufacturers instructions on the tin at all times.

Optimum application is achieved between 18°C and 22°C with good air movement and ventilation. Finished products should not be subjected to environments with temperatures of < 2°C.

Mixing Guidelines

  1. Catalyse 9 parts primer to 1 part 5CAT/200 by volume and mix well prior to use
  2. The catalysed primer is ready-for-use (RFU) but can be thinned up to 5% by volume with the recommended thinner, 5007/619, if required
  3. Under normal conditions these products will have a workable pot-life of 36 hours after catalysis
  4. We do not recommend the mixing of catalysed materials and fresh materials. Always mix enough material for the project you're working on

Application

  1. Apply with a spray applicator
  2. Leave adequate time between coats
  3. Do not apply more than 3 coats in one day, as excessive coating weights can lead to cracking or lifting
  4. Denib between coats to aid adhesion

Typical Finish: 1-2 coats Primer at 95g/m² per coat ( Dry Film Thickness ~ 43µ per coat), over-coated with Morrells White AC Topcoats and Fastmatch AC Topcoats.

Cleaning Equipment

Spray applicators can be cleaned after use with Morrells Equipment Cleaner.

Some Points of Note

  • Do not overcoat with 1K or 2K Polyurethane (PU) products
  • Use only the recommended thinner. Use of non-recommended thinner can cause uneven/patchy drying
  • Under catalysing or over catalysing can cause impairment of cure and cracking
  • Do not use over NC, Shellac or Pre-catalysed Sealers
  • Some timbers (e.g. cherry, maple etc) are prone to discoloration or reddening when using acid catalyst products
  • Douse all waste materials associated with this/these materials with water before disposal and avoid prolonged/excessive exposure to heat
  • Store all waste materials in secure metal container outside, away from combustible materials overnight
  • Product should be stored above 5°C and protected from frost
  • Out of scope with 2004/42/EC Directive

Using these products in systems outside these guidelines can lead to immediate and latent problems with the integrity of the finish.

Finishing

Good product, sprays nicely
I have sprayed hundreds of litres of this for other companies but this was the first time I've bought it for myself. It gives a perfect base for top coating, use minimal thinners, two heavy coats is normally enough on mdf. The only bad thing with it is that it gives of fumes for a long time after spraying.
