Pinholes and blisters

Engineer notes. Not a blog. Pinholes and blisters are not the same failure. Pinholes are outgassing and porosity. Blisters are moisture or vapour under a fresh film. Therefore the repair is not the same coat.
Pinholes and blisters after a cold membrane
Prime, wait, then apply at the build in the current TDS. Porosity Sealer and Primer Epoxy Plus are the catalogue names for prepared concrete before a cold membrane. Humidity Primer is the name when residual moisture is the issue. Primer Epoxy 100 is listed separately.
Repair is cut-back. It is not another thin roll over the bubble. The next coat still follows the overcoat interval on the sheet for that membrane and finish. Colodur Eco (aliphatic finish) has its own window.
However, site-failure language on this site is a specifier note. It is not a substitute for the method statement issued with the current TDS. In addition, do not invent kg/m².
What to write in the specification
First, name the primer. Then name the membrane. After that, name the finish. Read consumption from the current TDS, then the calculator.
See Porosity Sealer, Primer Epoxy Plus, and documents.
Outbound reference: EOTA.
A blister that is rolled over will return. Cut back, then recoat inside the window on the sheet.
Therefore the current TDS remains the source for mix ratio, overcoat and consumption. Then the calculator sizes the area. However, a number invented here would be a specification error. In addition, the application page is the schedule. First name the exposure. Next name the commercial product and the chemical type in the same sentence. After that, open documents. Also keep the finish on the same clause as the body. A sample, a colour or a photograph does not replace that sentence.
These notes do not replace the current TDS, SDS or a written specification. For pack sizes, mix ratio and kg/m², read the current sheet, then the calculator.
