The biggest cartridge here, at the lowest price
fischer Premium sanitary silicone, 310 ml, white, fungicidal
The largest and cheapest cartridge in this hub, with a fungicide and a claim about surviving cleaning — and not one cure time.
What you are getting
A 310 ml cartridge of white fungicidal sanitary silicone, stated as highly abrasion resistant, for expansion, corner, movement and connection joints in wet rooms, with adhesion named on chrome, stainless steel, anodised aluminium, enamel and glass.
The size and the price
310 ml, the biggest cartridge in this hub — the other three are 300 ml — at the lowest price.
For one bath joint that is irrelevant. For a bathroom being redone in a weekend, a cartridge that does not run out at the last corner is worth something.
The abrasion claim, which is unusual
A silicone joint in a bathroom gets scrubbed. A soft cure takes the brush marks and then holds dirt in them permanently, which is why an old joint looks grey even when it is clean.
Claiming abrasion resistance is a claim about how the joint looks in year three.
Skin time — how many minutes you have to smooth the bead with a wet finger before it stops taking one.
Full cure time — when the joint can be wetted, which for a shower is the thing that decides whether you can use it tonight.
Neither appears on any of the four cartridges here. Read the cartridge itself when it arrives; the figures are printed on it even when they are not in the listing.
And the chemistry
Not named. Acetoxy silicones smell of vinegar as they cure and can corrode some metals; neutral-cure ones do not. One cartridge in this hub names its chemistry.
