What primer should I use for self Levelling compound?
Setcrete™ Acrylic Primer is designed to promote the adhesion of Setcrete™ Floor Levelling Compounds to smooth absorbent and non-absorbent surfaces.
Does self-leveling compound need acrylic primer?
Primer. All of the self leveling cements require that you buy bottles of primer as well to coat your floor with prior to pouring the concrete. It is a rule but it’s only applicable if you’re pouring cement onto cement. If you have a non porous surface as your base primer isn’t crucial.
What is self leveling primer?
DESCRIPTION. NA 310 Self-Leveler Primer is a low-VOC, water-based acrylic primer that enhances the performance and adhesion of self-leveling underlayments on nonabsorbent surfaces such as ceramic tile, vinyl composition tile (VCT), epoxy moisture barriers and adhesive residue, as well as on profiled, absorbent surfaces …
Can you use SBR as a primer for self leveling compound?
The SBR to water ratio is too strong For priming porous substrates a 4:1 water to SBR would suffice If it’s skinned then just sand it off.
How do you use G primer?
Dilute Primer G with water from 1:1 to 1:3 to protect old floors before levelling, to fix the residual dusting and to provide even absorption of substrates prior to levelling or laying. Apply on perfectly dry gypsum or anhydrite surfaces (residual moisture content less than 0.5%).
How long should primer dry before leveling?
Wait 3 hours, then prime normally as above. Let primed surface dry to a tacky, transparent thin film (min. 3 hrs, max. 24 hrs).
Can you use SBR as a primer for self-leveling compound?
How long does it take for self-leveling primer to dry?
TEC Skill Set Self-Leveling Underlayment Primer typically dries in 30 minutes to 3 hours and is transparent in color when dry. Cure times are based on 70°F (21°C) and 50% RH. For full strength roller applications, dry times are 30-60 minutes. Colder temperatures and higher humidity will extend cure times.
What kind of primer do you need for self levelling?
Self levelling compound requires pva primer. Discuss Self levelling compound requires pva primer. in the Tile Adhesive area at TilersForums.com I bought some non latex based SLC from B&Q and it says on the packet to use pva as a primer before applying the SLC.
What do you need to know about self leveling compound?
It is a chemical mixture consisting of polymer-modified cement. In contrast to conventional concrete, self-leveling compound has high flow features and doesn’t require an excessive amount of water for proper placement. When you’re planning to lay tile or any other flooring, it’s essential that you have a completely level work surface.
Is it OK to use PVA in self levelling compound?
Leveling compounds almost always contain a portion of hydraulic cement, such as Portland cement, and here’s why it’s not a good idea to use PVA with such products. Latex leveling compounds are probably less sensitive to PVA than mainly cement based compounds, as they often contain less cement, and forms of vinyl ester, but I still wouldn’t use PVA.
Can you use self leveling compound on hardibacker?
You can apply self leveling compound directly to hardibacker, cement board or any other approved tile setting materials. If you are applying the self leveling compound to a concrete floor then it is important for the concrete floor to be totally clean and free of dirt and debris.
