ماستیک پلی اورتان DELTA



DELTA-PE2020is a flexible elastomeric, 2-comp polymer modified coating that waterproofs and protects

concrete, masonry, brick and some natural stone substrates with crack-bridging properties. DELTA has

excellent adhesion characteristics and provides a seamless system which can be left as the finished

surface, or can be top-coated with tiles, pavers, paint, or other coatings.

Primary Uses:

For waterproofing water structures, sewage treatment plants, exterior basement walls, retaining walls,

swimming pools, fountains, aquarium & zoo tanks, spillways, wet areas, under tiled applications, exposed

and decoupled roofs and sealing of expansion and construction joints with ASO-Joint-Tapes General


  • External waterproofing of old and new buildings against ground moisture, humidity, pressure water.
  • Horizontal waterproofing beneath masonry.
  • Internal waterproofing against humidity from outside.
  • For waterproofing of underground car parks, prefabricated garages, containers, service water tanks,

liquid manure containers, canalisation, areas of high humidity, terraces, balconies and swimming


  • For the fixing of ASO-Joint-Tape-2000, ASO-Joint-Tape-2000-S and ASO-Joint-Sleeve. Waterproofing

beneath tiles:

  • Safe and economic waterproofing beneath tiles in wet rooms, where water impermeability against long

term and permanent water table is demanded, i.e. in bath rooms, kitchens, shower rooms, on balconies

and terraces.

  • For waterproofing inside swimming pools.

NOTE: for applications were negative side hydrostatic water pressure can be anticipated use DELTA as

a base coat.


  • Crack bridging up to 2.59 mm
  • Easy to use – can be brush, spray, roller or trowel applied
  • Vapour permeable
  • Waterproof – resistant to 7 bar (positive side water pressure)
  • Can be tiled or left uncoated
  • UV, weather and freeze-thaw resistant
  • Bonds well to damp substrates without priming

Application Procedures:

Surface preparation

The surface must be clean, sound and fine pored. It must be free from grease, dust, pockets, cracks and

ridges. DELTA-PE2020is suitable for smooth concrete, screed, mastic asphalt, plaster, gypsum board

and masonry. Coarsely pored surfaces like gutter blocks or precast concrete blocks have to be grouted

with cement mortar, ASOCRET–FS or DELTA Prime highly absorbent surfaces like light weight concrete

or gypsum boards with ASO-Unigrund to improve adhesion. Use suitable methods to prepare the

substrate dependent on its condition such as e.g. brushing,vacuuming, grinding, milling, shotblasting and

water jetting.


  • Concave moulding, ledging corner: Form between masonry and foundation a concave moulding of 4 cm

length with pre-blended mortar ASOCRET-RN or cement-based mortar and ASOPLAST-MZ additive.

  • Existing cracks can be sealed with DELTA by embedding the ASO-Joint-Tape-2000 into the first layer.
  • For moving cracks and construction joints use ASO-Joint-Tape-2000-S.


Pour approx. 2/3 of the liquid component UNIFLEX-M into a clean container and add DELTA powder

component whilst stirring until a lump free mass isachieved. Mixing time of 2 – 3 minutes is required. After

that, add the remaining UNIFLEX-M and stir until a uniform consistency is achieved.

NOTE: Depending on application, max1.5% (approx.0.5 l / 35 kg) water can be added during mixing in

order to adjust application consistency.

Method of Application:

The substrate must be damp during the application. DELTA-PE2020 can be applied by brush, trowel,

roller or appropriate spray equipment. At least two coats of DELTA-PE2020are necessary. The applied

thickness of the waterproofing must correspond with the required minimum thickness for the expected wet

duty conditions.


Only apply the second layer when the first coat will not be damaged by further applications (at +20 °C

after 4 hours at the earliest). Due to the possibility of crack formations avoid applied thicknesses greater

than 2 kg/m2 (= 1 mm dry film thickness) in one application to prevent the formation of cracks. For

protection of the DELTA-PE2020waterproofing the ASO-Systemvlies-02 may be embedded into the last

  • In hot and humid climates coating may become slightly tacky/sticky during the curing process. If this

occurs, mist coating with water 24 hours after application to ensure complete hydration of material.

  • Negative water pressure can lead to delamination during frost conditions.
  • DELTA-PE2020can be overplastered and also be painted with diffusion permeable and solvent-free

paints (no silicate paints).

  • In areas with high humidity and inadequate ventilation (i.e. in water tanks) allow for extended drying


  • Avoid direct sunlight during application.
  • Pre-dampen the surface prior to application of DELTA.
  • Protect areas not be treated from DELTA-2K/M.
  • Eliminate direct contact with metals such as copper, zinc and aluminium with pore-tight, priming agent.

A pore-tight primer can be produced with two applications of ASODUR-GBM. Apply the first coat

thoroughly to the cleaned substrate and carefully brush in. As soon as this coat has dried sufficiently, so

that it can no longer be brushed through (within approx. 3 to 6 hrs) then brush on the second coat of

ASODUR-GBM and broadcast with quartz sand (grain size: 0.2 to 0.7 mm). Consumption approx. 800 to

1.000 g/m2 of ASODUR-GBM. For sealing of PVC and stainless steel flanging, abrade the flanges and

degrease with isopropanol or acetone. Apply DELTA-PE2020and bed in the ASO-Jointsleeve or

alternatively as ADF-pipe seal and fix without voids and folds.

  • To increase pot life/working time at higher temperature store material in a cool environment above +5°

C and only expose to warm temperature
