About Rust-Oleum Dacfill HZ
Rust-Oleum Dacfill HZ is highly elastic and resistant to standing water one hour after surface drying. It has excellent resistance against extreme variations in temperature, atmospheric pollution and UV-rays and builds an abrasion resistant rubber like coat without joints or seams.
- Quick drying water-resistant coating soon after application
- Quickly recoatable, two coats in one day
- Super-elastic and hard-wearing
- 100% watertight and vapour-permeable
- Resistant to UV radiation, acid rain, heat, frost and pollution
- Easy to apply with a brush, roller or airless spray
- Excellent resistance to major changes in temperature
Surface Preparation
The substrate must be well clean and dry, free from flakes, gravel, dust and dirt.
Fill up joints with Elastofill, bridge active cracks with "Dacfill bridging mesh" and apply one of the following priming coats:
On porous concrete, hard PVC and polyester -Primer 44HS.
On very smooth concrete - Noxyde diluted with 25% water.
On iron and steel - undiluted Noxyde.
Roofing or bituminous materials over 1 year old can be coated directly with Dacfill HZ depending on its condition.
Application and Thinning
Brush: Square brush. Do not dilute.
Roller: Long pile roller. Do not dilute.
Air-atomised spray: Not applicable.
Airless spray: Nozzle: 18 - 23 / Pressure: 220 bars: Do not dilute
Mix the B to the A component stirring mechanically. Plan to use the mixed material during the same day.Unroll the Dacfill-mesh on the dry and clean substrate and fix it to the substrate with a first coat of Dacfill HZ (1-1.5 kg/m2) by roller. Mesh overlapping must be at least 5 cm. After drying, a second coat of Dacfill HZ is to be applied by roller or by airless spray so that the structure of the mesh is not visible.
