Product Information

Full details

This Johnstone's Trade Stormshield Flexible Primer Undercoat in Grey is designed for professional decorators and DIY enthusiasts needing a durable, long-lasting primer for exterior woodwork and primed metal. Its key benefit is superior flexibility, preventing cracking and peeling over time, with a lifespan of up to 8 years. A caveat to consider is the need for a universal primer on bare surfaces before application. This microporous coating provides excellent protection and prepares surfaces for topcoats like Stormshield Flexible Gloss or Satin.

Troubleshooting

Primer not adhering to surface

Ensure the surface is clean, dry, and free from dust, grease, or contaminants. If applying to bare wood or metal, confirm that Johnstone's Trade Universal Primer was applied first.

Cracking or peeling after application

Verify that the surface was adequately prepared and that the primer was applied to a dry surface. Ensure sufficient coats were applied and allowed to dry fully before the topcoat. Check for extreme temperature fluctuations during drying.

Poor coverage

Apply an additional coat of the primer. Ensure you are using the correct number of coats (1-2 coats) as recommended for the surface type.

Inconsistent finish

Ensure consistent application technique with the brush. Avoid overworking the product. Apply in appropriate environmental conditions (avoid high humidity or very low temperatures).
