Dry vacuum.
Acid rinse solution in a spray bottle set as a fine mist. very lightly mist all over and lightly brush in. Probably use about 1/2 litre on the whole suite.
Protector will be about 1.5litres +/- for whole suite, depending on size.
If using solvent protector, no acid rinse, but ventilate room, keep others out, wear solvent mask plus usual PPE.
Do not use suite for minimum of 24 hours. protector dries like paint. It may feel dry, but easily rubs off until fully cured.
Stand suite on drop sheet whilst working as overspray can be considerable.
Safe and happy protecting
