Agilia Screed A

Edge Detail

Polythene foam strips (6 mil/150 um) or other compressive material must be placed around the perimeter and other vertical elements. In the insulation boards are not supported they can be laid into a grout or slack screed mix to aid in support.

Substrate Types

Agilia Screed A can be on substrates made of:

• Concrete Slab
• Precase
• Tile
• Vinyl
• Insulation
• Thin carpet
• Timber 

For chipboard or similar products the screed must be unbonded making sure the board has adequate ventilation underneath once the compound is laid. 

Ambient Conditions

Agilia Screed A can only be laid when the temperature is between 5-30 celcius.  In Ontario heating must be considered for a winter season installation.  The substrate should not be frozen and ideally within the temperature range of the air.  The relative humidity should be below 60%.  No curing is required but the floor should be protected from high wind, sunlight and direct heat for 72 hours. 

Joints

Joints are not required for areas under 10,000 square feet. 

Slump-flow Measurement

When Ontario Self Leveling Concrete arrives on site the sump flow will be 240-270mm for Agilila screed A.  We consult with Lafarge to ensure the flows are accurate.

Following Placing

The room where the screed is installed should be sealed for 48 hours.  Foot traffic can resume in 24 hours-48 hours depending on climate conditions.  Surface laitance should be removed by sanding the surface. 

Residual Moisture Content

Before any product is laid the floor should be check by a certified concrete moisture tester.  Ontario Self Leveling Concrete has certified concrete moisture testers on staff.  Screed A should reach a moisture content of 0.5% within the first month before receiving an epoxy coating.  While tiles and carpet can be installed after 2 weeks.  Forced drying should be avoided when possible especially within the first 3 days.  

Bonded Applications

Agilia Screed a is placed directly on the concrete surface.  Naturally the surface must be kept clean and dry.  Any holes and gaps must be sealed to prevent leaking.  Before placing any product a primer is required to ensure proper adhesion.  By scarring the surface of the concrete adhesion and bonding characteristics are greatly increased.  

Unbonded and Floating Screeds

The base is first cleaned and then a polythene sheet is put on the floor.  It must be level enough that insulation boards will not rock up and down.  To support the insulation boards a thin layer of screed can be laid.  The polythene layer should have a minimum thickness of 150um and a maximum thickness of 350um.

Thermal and Acoustic Flooring & Radiant Heating

Agilia Screed A can be laid as an unbonded coat over many types of inflexible insulation board and acoustic dampening foam (max thickness 35mm)

Radiant Floor Heating

Agilia Screed A is the ideal product to use when installing in floor radiant heating elements, regardless if you choose water or electric for your project.  Since Agilia Screed A can be laid so thin (30mm) it is the best product on the market for this use.  The thinner the floor the faster and more efficiently the system can release heat into the environment.  Agilia Screed A has great compaction which eliminates air bubbles further increasing the energy efficiency when compared to traditional screeds.  All in all, Agilia Screed A is going to perform 3 times better then cement based screeds.
