Instructions for use
Before proceeding, please read the following information application carefully to ensure that proper procedures are fully understood.
Ceramigrade Abrashield is a two component, solvent free, fast curing,
synthetic repair compound. It consists of large ceramic particles in an
epoxy matrix. Areas of application: Protection of surfaces subject to
extreme wear and abrasion caused by solids or slurry. Specifically meant
for Dredgers and Cement carriers facing heavy abrasion combined with
medium and light impact.
1.Surface preparation
A Heavy contamination due to oil or grease must be removed using a
cleaner. Where possible, abrasive blasting is the preferred surface
preparation.
B Remove all loose rust and surface coatings
C Roughen the surface preferably with abrasive blasting to SA.
Alternatively a die grinder, needle scaler or angle grinder may be used.
If grinding make sure the surface is roughened, not polished. Where
grinding or needle gunning is used, the surface should be cross-scored to
improve adhesion.
D Surfaces subject to abrasive wear is often gouged out and highly
polished and must be cross-scored to secure bonding.
E Where deep abrasive wear andor a high build up is required, bonding
can be secured and improved by welding small angle irons to the
surface to be coated. “Anchoring “ the product in this way will give a
better key.
2. Mixing
Transfer the content of Base and Activator containers from the
respective jars onto a clean mixing plate. Mix in the ratio indicated.
Preferably the mixing ratio should be by weight. Lids should be replaced
immediately after use. The two components should be thoroughly
mixed until completely streak free and a uniform colour is achieved, using
the spatula provided.
3. Application
Prepared surfaces should be dry. Using the spatula provided the mixed
material should be spread evenly onto the prepared area, working the
material into groves and surface defects. First pressing and squeezing
a thin layer of product hard onto the surface secure a good bonding.
Afterwards add more product, building up to the required height.
Guide to coverage rate: 1,8 Kg per 1m
on 1 mm thick application.
4. Machining
Ones the Ceramigrade Abrashield has cured for the minimum time indicated
in the Curing Properties Section of the product specification sheet,
sanding, grinding and machining etc. can be carried out using standard
engineering practices.
5. Cleaning
All equipment should be cleaned IMMEDIATELY after each use with
a cleaner. Failure to follow this

Users should determine the suitability of the product for their own particular
purposes by their own tests. procedure will result in application
equipment becoming unusable.
6. Health and safety
As long as normal good practices are observed Ceramigrade Abrashield
can be safely used. A fully detailed

Ceramigrade Abrashield can also be used in combina- tion with the hard surfacing electrode Abratech-330 to
fill in between runs. The welding runs give the polymer side support and stability.
Improve addition by “Anchoring” the product by welding small angle irons to the surface to be coated.
