Waterproof paint construction programme and alternative proposal

I. Preamble

Polyaspartic polyureaWaterproof coatingsBy virtue of its rapid curing, superior waterproofness and environmental advantages, it has become the preferred of a new generation of waterproof materials. This paper will provide a detailed analysis of the construction options and options for waterproof paints for the polyaspartic polyurea.

II. Substrate processing requirements

2.1 concrete substrate

• Water content: ≤3% (tested with water content tester)
• Strength: ≥C25; surface pull-off strength: ≥5MPa
• Flatness: 2m rectangular check, gap ≤3mm
• Cleanness: no oil, no ash, no loose matter

2.2 Metal substrate

• Rusting grade: Sa2.5 class (spray treatment)
• Surface roughness: Rz40-70μm
• Cleanness: no oil, no water, no dust

III. Construction process

3.1 primer Construction

Materials:Primer for polyaspartic polyurea systems

Usage:0.2-0.5kg/㎡

Methodology:Roll or brush, evenly covered

Dry time:Touch-dry ≤30 minutes, hard-dry ≤2 hours

Painting in 3.2

Materials:Waterproof paint (WP series)

Usage:0.5-0.8kg/㎡/ channel

Methodology:Rolling, brushing or scratching, cross-cutting construction

thickness:Single-lane wet film thickness 0.3-0.5mm

Recoating interval:Touch-dry after 30 It'll be the next construction.

3.3 Enhanced Layer Construction (optional)

For vulnerable areas such as cracks, tubing roots, angular angles, it is recommended that enhanced cloths (polyester or glass fibre cloths) be laid to improve the fracky resistance of the water-proof layer.

3.4 coating works (optional)

For outdoors or decorative scenes, a polyaspartic polyurea coating can be constructed to improve the value of the decoration.

IV. Recommendations for product selection

4.1 Waterproof house

Recommended products:Waterproof roof.

Construction thickness:

Characteristics:Excellent, weather reistance, long-term exposure, non-pollution.

4.2 Waterproof basement

Recommended products:Waterproof outside walls

Construction thickness:

Characteristics:High adhesion, resistant to backwater pressure, suitable for surface and backwater

4.3 Waterproof bathroom

Recommended products:Polyaspartic polyurea kitchen and bathroom waterproofing Polyaspartic polyurea kitchen and bathroom waterproofing

Construction thickness:

Characteristics:It's not toxic. It can be applied to the wet environment.

4.4 Waterproof pool

Recommended products:Waterproof pool dam.

Construction thickness:

Characteristics:Long-term water impregnation, environmentally safe, suitable for drinking water ponds

Quality acceptance standards

• Gravity of coating: meeting design requirements, allowing deviation ≤10%
• adhesion: ≥2.5MPa (concrete concrete), ≥2.5MPa (metal substrate)
• Closed water test: 48 hour no leakage
• Appearance: even coating, no bubbles, no cracks, no stripes

VI. Construction care

• Construction temperature: 5℃ - 40℃, relative humidity ≤85%
• Substrate temperature above dew point temperature 3℃
• No construction in rain, snow, fog
• The mixed materials should be exhausted in 30 minutes
• After construction 24 Avoid rain or tread within hours

Concluding remarks

Polyaspartic waterproofing paints have become the preferred material for waterproofing works by virtue of their superior performance and ease of construction. Junaimei provided professional product selection and construction guidance services to clients.
