G4 Black Pond Seal 1kg

G4 Black Pigmented Pond Sealer is a moisture cured, coloured polyurethane based stone and concrete sealant mixture.

This forms a non-porous seal on concrete, brick, or porous stone. ‘Liquid pond liner’, this can be used building new ponds, watercourses/waterfalls, water features, and other similar projects.

Usage: (this will depend on porosity of material being treated):

• Can be applied in temperatures as low as 0°c, and in high humidity too.
• Minimum of 2 coats required, although we recommend 3.
• 1 kg treats approximately 2 sq m (21 sq ft) allowing for 2-3 coats.

Repairs:

• For small fissures and hairline cracks a pointing mixture can be made up of one part G4 to three parts dry sharp sand. (Sand must be totally dry to make up mixture.)
• The repair can be sealed after 24 hours with the usual two to three coat top application.
