Resin-based flooring

solutions are extremely

durable and when

properly installed offer

clients a seamless,

hardwearing and highly

resistant finish.

However, avoiding blemishes in the

finished surface - including bubbles

and blisters - requires careful

preparation and attention to detail.

Bubbles can either appear all over the floor

or in localised honeycomb clusters.

@dr_flowcrete www.flowcrete.com

There are three main causes of bubbles

or blisters in resin flooring:

Air bubbles become trapped in the resin material during mixing and remain during cure

Moisture vapor transmission

Applying resin material onto a porous substrate

How can we prevent or eliminate the imperfections from forming?

@dr_flowcrete www.flowcrete.com

Ensure that the component products are

thoroughly distributed during the mixing

process using a slow helical spinner drill

@dr_flowcrete www.flowcrete.com

Ensure the material is pre-formulated

to suit the weather and temperature

conditions at the time of installation

@dr_flowcrete www.flowcrete.com

Avoid high temperature

or low temperature

conditions wherever possible

@dr_flowcrete www.flowcrete.com

Ensure that porous substrates

are properly sealed and

primed to prevent outgassing

@dr_flowcrete www.flowcrete.com

This includes filling

all cracks, holes

and dents prior to

installing the finish.

Typically polyurethane solutions offer

breathability on a moist or damp substrate…

Epoxy solutions do not and will require the

application moisture tolerant primer or a

damp proof membrane prior to installation.

Most importantly, ensure that

the resin flooring is installed

by highly skilled, highly trained

application teams recommended

by the manufacturer to ensure

the best finish on your project.
