Application
Surface preparation: Surface preparation is crucial before applying sealant. The joint surface must be dry and free from dust, coatings, oils, grease, and loose particles. Clean using a wire brush, emery paper, and compressed air. Wipe oil and grease with a solvent-soaked cloth.
Back-Up Material: Insert a compressible rod (polyethylene, polyurethane, neo- prene) to control sealant depth and sup- port tooling.
Priming: Apply sealant primer on porous substrates like concrete & wood in two coats with a 30-minute interval.
Masking Tape: Use polyethylene, cello- phane, or cloth tape to protect edges, removing it after tooling.
Application: Mix hardener with resin until uniform. Pour directly into joints, allowing it to self-level for a smooth finish.
Packing
Resin (Part A): 3680 gm in a 4 Kg container.
Hardener (Part B): 320 gm in a 300 ml sachet.
Formula
To calculate the weight (kg) of Proxon PSPG sealant for a joint (m), use this formu- la:
Weight = (Joint Length) × (Formula-Specif- ic Calculation).
This ensures accurate sealant estimation.
Weight in kg = SG × W × D × L
1000
where W & D are in mm and L is in metre. SG = Specific gravity of the sealant
W = Width of joint D = Depth of joint
L = Length of the joint
Approximately, 1 Litre of PRIMER would cover 6 to 7 Square metre of the joint area.
