FAQ

Frequently Asked Questions

Is there any media used in the water?

We use a very fine slurry utilizing water, as well as various grades of blast media to return parts to their natural metal finish and colour.

Do I really need to strip everything first?

It’s always best if everything is stripped down to the bare minimum. Holes and openings should be taped or sealed.

What is the best way to get the parts to you?

Please give us a call before sending a parcel so we can be sure to be available.
(Please be sure to register & insure your goods)

How much does Hydroblasting cost?

An estimate for each job can be provided prior to starting. We charge by time. Its often cheaper than you expect

What can be hydroblasted?

Most metals, including:

Stainless steel, Aluminium, Bronze, Magnesium, Titanium, Brass, Copper

Excellent candidates for Hydro blasting also include most alloy parts e.g. cylinder heads, intakes, turbochargers, throttle bodies, carburettors, motorcycle barrels, brake callipers, fork legs, triple trees, wheel hubs and alloy engine casings. Please note that Magnesium does not shine like aluminium because it forms an oxidation layer turning a dull grey colour.

What about paint stripping?

Paint must be stripped using dry blasting or paint stripper prior to Hydro blasting.

Must I dismantle everything?

Yes the process works best when all components are stripped to their individual pieces.

Can cast iron be hydroblasted?

Yes, Hydro blasting can remove surface rust but is not designed for heavy rusted components. Traditional sand blasting may be a better solution for Steel or Cast parts.

What about flash rusting?

We can add a flash rust inhibitor that will stop flash rust for a few days on steel. It is recommended that all steel items be sealed or plated as soon possible after Hydro blasting.

What sort of finish can I expect?

Different castings produce different results. Sand cast parts come out exceptionally well and have a beautiful satin lustre. Die cast parts usually have a matt satin finish although this varies according to the quality of the casting. Stainless steel has a matt satin finish and the gloss finish will be dulled.

The action of Hydro blasting also gently peens the surface of the metal closing the pores and making it more resistant to further dirt and grime.

What media do you use?

We use a selected fine grade, high quality glass bead. Because glass beads are round and the cleansing action is by flow rather than impact, the finish is much finer than traditional angular media used in dry blasting.

Can Hydro blasting strip anodising?

Yes it can, but the process is time consuming and therefore costly. It may require the item to be dry blasted prior to us receiving it.

What about media residue?

Although we take care to block any passages we don’t want media to enter, there is always the risk that some media residue may remain. We rinse all parts after processing and dry with compressed air but the final responsibility rests with the customer to check that no media traces remain prior to re assembly of the part.
