ESG17 |
18.0 |
Used for heavily pitted surfaces, and for removing elastomeric or extremely thick coatings. Cleans to Sa 2.5 or Sa 3standard. Not recommended for use in any wet or damp environments. |
100–125 |
|
Aluminium Oxide 14/24 |
ESA16 |
18.0 |
Removal of multi-layer coatings from steel or where a greater profile is required prior to the application of high-tech composite coatings. |
80-100 |
|
Aluminium Oxide 30/40 |
ESA30 |
18.0 |
The first choice for many industrial applications. On steel it removes mill scale, rust and paint coatings and yields an Sa 2.5 or Sa 3 surface quality finish. |

|
Aluminium Oxide 30/40 |
ESA30F |
15.0 |
Fine Grade material used on special applications or in specialised equipment. |
60-80 |
|
Garnet 30/60 |
ESGT30 |
18.0 |
Multipurpose media designed for limited reuse where recovery of spent media is difficult. |
50-60 |
|
Aluminium Oxide 60/80 |
ESA60 |
13.5 |
Removal of 1 or 2 layer coatings on steel or fibreglass or weld cleaning prior to coating. Removes light coatings from steel and aluminium substrates, or can be used to profile previously painted surfaces. Cleans to Sa 2.5 or Sa 3 Standard. This grade can also be used to refurbish concrete, stone & masonry. |
40-60 |

Aluminium Oxide 60/80 |
ESA60F |
15.0 |
Fine Grade material used on special applications or in specialised equipment. |
40-60 |
|
Aluminium Oxide 80/100 |
ESA80 |
13.5 |
For more delicate work on wood or stonework, concrete, masonry or on virgin steel for cleaning. Removes light coatings from steel and aluminium substrates, or can be used to profile previously painted surfaces. Cleans to Sa 2.5 or Sa 3 Standard. |
35-50 |
|
Aluminium Oxide 120 |
ESA120 |
13.5 |
Selective coating removal where a small profile is required. Removes light coatings from steel and aluminium substrates, or can be used to profile previously painted surfaces. Cleans to Sa 2.5 or Sa 3 Standard. This grade can also be used to refurbish concrete, stone & masonry. |

100% Sponge… light cleaning applications only. No abrasive added. |
0 |
Specialist medias (e.g. use on carbon fibre, turbine cleaning and other applications) are also available, subject to special order, manufactured with other mineral and non-mineral abrasives.
EnviraSponge can be manufactured to meet any specification, where low dust, low rebound and reduced waste is required.
Terms: Returns: 15% restocking charge subject to conditions.
- Profile is based on cleaning mild steel at 6 bar / 85psi.
BUDGET COST ESTIMATES
Using No.8 – 12.5mm nozzle @ 85psi / 6bar – 400CFM / 10.5 cu.mtr/min
As a rough guide, estimate that ESA30 media removes 3 / 4 layer paint coatings and rust from flat / uncomplicated steel substrates at 3 sq. mts to 5 sq.mts per hour to SA2.5 standard with profile of approx. 65 microns. Each 18kg bag of media strips approx. 0.5 sq mts on each run. So if you achieve 6 – 8 media recycles you can anticipate 3.0 to 4.0 sq.mts of sponge-blasted surface per bag. For abrading virgin steel and / or for lower profile specifications a greater number of sq.mts per hour (up to 12) can be achieved. For every project – always make a test on a typical area to get accurate rates and definitive costs.
