Johnstone's Aqua Guard Primer Undercoat - Tinted Colour Match

Johnstone's Trade Aqua Guard Undercoat Primer is a water-based undercoat designed to prepare interior wood surfaces. Delivering excellent adhesion to previously painted surfaces and most porous substrates, it ensures a smooth, reliable base for topcoats. Ideal for use under the Johnstone’s Aqua Guard Gloss, Matt or Satin, it is also suitable for use with other water-based paints. Stain blocking, it effectively blocks wood resins from staining through when applied to bare timber, protecting the quality of the final finish.

• Excellent opacity & adhesion
• Ideal for trims
• Blocks resinous timber staining
• Quick Drying
• Easy Application
• Low odour & VOC
• Tintable in 16 000+ colours

Tinted Colour Information

Tinted paint is custom mixed in house at Next Day Paint using our Jonhstone's Trade tinting machine. We mix the paint on site, which means we can offer our usual fast delivery with no extra delay.

Tinted Colour Match paints can't be cancelled or returned as they are tinted to order.

A tinted primer can be used to help obtain the true depth of colour for your top coat or to reduce the amount of coats required when a drastic colour change is occurring. A tinted primer will not necessarily be the same colour as your selected topcoat. It will be tinted towards the topcoat colour and generally lighter in shade. For example if your topcoat is black your primer may be a shade of grey. If you are unsure about when a tinted primer is required please contact us and we can advise further.

Ensure the surface is clean, dry and free from dirt and grease.

• Remove any loose or flaking material
• Rub down previously gloss painted surfaces with fine waterproof abrasive paper and rinse thoroughly.
• Prime bare wood with Johnstone’s Aqua Guard Primer Undercoat. Prime all other bare surfaces with Johnstone’s Trade Advanced Multi Surface Primer.

Note: for strong colour changes it is recommended to use Johnstone’s Trade Aqua Guard Primer Undercoat in the final colour of choice.

Always test a small area of the surface to be painted to ensure you are happy with the finished results

• Stir thoroughly before use to ensure the paint is completely mixed.
• Johnstone's Trade Aqua Guard Primer Undercoat can be applied by brush, roller or sprayer. Avoid overspreading. For best results use a synthetic brush.
