Barcode: 5060763590151

ProJoint Porcelain Primer is a polymer- and fibre-modified slurry designed to improve adhesion of porcelain paving by controlling suction and strengthening bonds on challenging surfaces.

Who This Product Is For

This primer is for professional landscapers, paving contractors, and experienced DIY users installing porcelain paving systems. It suits those working with porcelain slabs, setts, or ceramic tiles on outdoor surfaces.

The product is appropriate for projects where strong adhesion is needed on non-porous or difficult substrates like porcelain, concrete, or ceramic tiles.

Key Features

• High-Performance Formula: Provides strong adhesion and reduces suction on difficult substrates.
• Quick Drying: Dries within 30–60 minutes.
• Easy Mixing: Add water to the powdered primer and mix in the provided bucket.
• Large Coverage Area: One bag covers 10–13m².
• Wide Compatibility: Suitable for porcelain, concrete, ceramic tiles, and natural stone.

Practical Applications

ProJoint Porcelain Primer works for outdoor patios, driveways, walkways, and other hardscaping projects. It creates a reliable base for porcelain or ceramic tiles on sand and cement bedding. It provides a foundation for laying setts in areas exposed to harsh weather conditions.

How This Fits Into a Typical Job

This primer is used during surface preparation, before laying paving slabs. After cleaning and preparing the substrate, the primer is applied to create a bonding layer. Once dry, the paving installation can proceed using sand and cement bedding.

The product extends the working window, allowing slabs to be laid within 14 days after priming while maintaining surface readiness.

How to Use

1. Surface Preparation: Clean the surface thoroughly, removing dirt, oil, and loose materials to create a smooth, dry base.
2. Mixing: Add water to the powdered primer in the provided bucket and stir until the mixture is well combined. Only prepare as much as needed for the project area.
3. Application: Apply a thin, even layer of primer using a brush or roller to provide complete coverage.
4. Drying Time: Allow 30-60 minutes for the primer to dry fully before laying paving slabs.
5. Laying Slabs: Once dry, you can lay slabs immediately or within 14 days. Keep the primed surface clean and free from debris.
