Need to put a bit down to finish off a freshly concreted screed over an old hearth. I've read somewhere that it requires the surface to be primed but no mention of what to use?
Anyone advise please?

Hi Fred
Not actually used it myself (yet) but looking to level my garage floor so done a little research
Wickes sell 'Setcrete Floor Leveling Primer' , which seal porous, dusty surfaces prior to pouring the levelling compound
Around £12 I remember but will probably be way too much quantity for your small area but ........
Don't ever be tempted to use PVA ...... may well end in tears mate
Spotted this while following your link.

Bit cheaper and only need a small quantity. Looks like it will do the job. Says it can be added to screeds or applied as a bonding agent.
Am I missing something daft?

Perfect, dilute at 3 to 1 or 4 to 1, I didn't recommend SBR, as usually it's on comes in 5ltr can, & couldn't find in a smaller amount, good to see Wickes doing a 1ltr can.
The great thing with using SBR is it doesn't re-emulsify like PVA wet you wet it.
Use it for years,leveling compound at previous place was down for years,& still is, & never lifted, here it's be down seven years.
Depending on the suction of the surface you can vary the dilution rate up to 8 to 1 if it's a porous surface, usually one coat is enough, but you can let it dry & apply a second if need be.
Regardless of brand of SBR, I dilute I as see fit for the job.
Found a linky. http://www.chilternslurry.com/wp-content/uploads//12/Technical-Data-SBR1.pdf
Normally I'd just use a standard acrylic primer but SBR will definitely do the trick; just get your levelling compound down whilst the SBR is still tacky to the touch
Difficult finding acrylic primer in 1ltr can,only know of Topps Tiles selling it, but Wickes 1ltr SBR is half the price.
I usually just get 5ltr tubs as they'll get used up on other jobs eventually.
Same here.
Trouble is a lot of additives are 5ltrs & geared up for trade use, I think firms like Everbuild are missing a niche in the market not doing say 2.5ltr, even 1 ltr can of products like 204 Evermix 3 in 1 or 406 Stabilishing Solution for diyer's.
Evening all. First-time poster
Can I double-check I'm getting this right?
I have a VERY dusty workshop floor that I want to seal and level.
If I'm understanding the post correctly, I use this stuff first http://www.wickes.co.uk/Setcrete-Hi...ling-Primer-2-5L/p/#tab-reviews_content and then put this stuff on top, ideally while the primer is still wet http://www.wickes.co.uk/Setcrete-Deep-Base-Floor-Levelling-Compound-20kg/p/.
It's proving impossible to clean the surface prior to priming as any sweeping just lifts more cement dust - will that be a problem? Any tips for getting round this?
I'm not going to be adding any vinyl or carpet, so I'm just hoping that this stuff will work ok as a wearing layer.
Thanks

If the floor is really bad I would look to use something like Everbuild's "Concrete Hardener and Dust-proofer", the down-side being that you need to wait another 28 days before primering and screeding.
The majority of levelling compounds are for simply er, well, um, levelling and are not recommended to be used as the finished layer
Strongly advise that you check all product details regarding this point to check suitability
Could always go over compound with T&G chip flooring or OSB 3, then a couple coats of floor paint if you want. Any suspicion of damp from floor then add a poly membrane
If you want a levelling compound as a wearing surface, then a industrial floor screed which needs to be polymer resin based, not latex based.
A polymer resin screed will give you a very hard surface and can be applied to only 3mm thick if required.
I've used this stuff before for garages - gives a decent wearing surface too, as opposed to standard floor screed

Now thank is a useful linky, thanks.
Nice, it's a one part product, some of the industrial compounds are two or three parts.
Still need to use a acrylic primer before laying it.
The establishment of a new floor requires a carefully examined process. Preparation of the floor using a floor primer is vital for not only saving your time and effort, but money as well.

A floor primer provides a plethora of benefits for the finished floor. If you want the very best adhesion and endurance of your flooring in the years to come, then you must consider the use of a floor primer.
Here a few benefits of a floor primer you must know about:
1. Adhesion
The floor primer pierces the substrate and enables the bonding of the floor overlay to the substrate. Floor primer guarantees better adhesion of the floor overlays to the substrate. Thus, providing your floor an extended life as well as minimize the risk of the coat breaking or chipping.
2. Reduces Emerging of Bubbles
Using floor primer will significantly minimize the bubble emerging chances in the coat. This is particularly common in thicker coats such as self-leveling, where air locked in the concrete slab might generate bubbles of gas and pinholes in your coating. So, by properly priming and closing off the substrate, you're minimizing the risk of gas and air being liberated.
3. Resistance Capabilities
A floor primer features several kinds of resistivity, which adds to its fame as a hardy flooring technique.
Floor primer is shock, chemical, heat and water resistant. This makes it perfect for garages as your cars might emit corrosive chemicals.
4. Minimizes Absorption
If you are looking for more details, kindly visit Self Leveling Compound Basecoat Primer.
Priming will minimize the chance the products being assimilated by the substrate. Sometimes substrates may more absorbent. Therefore, if you attempt to apply a coat on it, you might get a dull matte look as the substrate has absorbed all the liquids.
That's why you must use floor primers to block off the surface before applying floor products.
5. Ease of Maintenance
Another benefit of floor primer is its easy upkeep. By coating the substrate, there's a reduction of dust and cement particles discharged onto other surfaces in the room.
Even bacteria, grime, germs, and other contaminants don't adhere to floor primer, so it's an effective and sanitary step.
6. Eco-Friendly
Floor primer is an eco-friendly option with ZERO VOCs.
The Functional Basis for Floor Primers
Floor primers penetrate more into the substrate's pores, thereby enhancing the floor's surface durability to delamination. The floor primer's surface builds a thin coat that is convenient as it develops a foundation for the denser base coat on either porous or non-porous surfaces. These systematized bonds produce long-lasting outcomes that can withstand any varying situation.
