Store in the dry conditions between 5 – 30 °C. Under shield condition, out of direct sunlight and rain. Put away from sources of heat and naked frames in the original, unopened packs. If stored at high temperatures the shelf life may be reduced. Estoflex PU 880 should be protected from frost.
12 months in an unopened and undamaged packaging.
Application condition
1. Relative Humidity (RH) 65 – 85%.
2. Ambient Temperature 5 – 35 °C.
Application Instruction
1
Surface Preparation
Long term durability of any floor/wall waterproofing
is determined by adhesive bond achieved between
waterproofing material and substrate. Correct and
proper substrate preparation prior to body coat
application is the most important step.
New Concrete
Must be aged for a minimum of 7 days. Use only Estoflex PU 880 Primer. Ensure the substrate is clean, sound, and free from contamination such as oil, grease, mortar, paint splashes, or curing compound residues. Excessive laitance can be removed mechanically.
Old Concrete
A clean, sound substrate is crucial for maximum adhesion. For new concrete surfaces, remove laitance mechanically. Use a proprietary chemical degreaser or hot compressed air to remove oil and grease. Repair any damaged areas or surface irregularities with Epoxy Putty.
2
Excessive dust, debris, and others contaminant material should be removed using high pressure blower or industrial vacuum cleaner.
3
Priming
Apply Estoflex PU 880 Primer to the concrete to shield against high moisture conditions (>5% concrete moisture), allowing the Estoflex PU 880 system to be applied even during the rainy season. Apply the primer using a brush, roller, or sprayer and wait until tack-free.
4
Placing
Apply using a brush, roller, or squeegee, depending on the application conditions. Apply 3 layers at 0.5 Kg – 1.0 kg/m² coverage to achieve a complete waterproofing layer. Pinholes will be sealed after the second layer. Apply each layer in intersecting directions.
