This technique just isn't regarded as being authentic polished concrete as You can find little physical refinement from the concrete slab. Nonetheless, it does present an identical look to polished concrete and should be acceptable in a few places. Commonly this system is referred to as a "50 % polish" as typically the surface is simply processed by means of three techniques of grinding (50 percent the ways of what a real polished concrete floor is processed). The surface is densified so the advantages of the densifer are inherited, then a concrete sealer or simply a superior buildup of the concrete guard is made use of to produce a shine.
Background #one: I've a two year old home. The basement to date is kind of dry (sandy soil and very good foundation drainage). We lived there right before we rebuilt your house and by no means experienced any water problems and no odor/mildew with carpet around slab.
It seems to me that a little something like Dricore doesn’t supply adequate insulation to stop condensation, and an entire 1.5 inches of froth for a vapor barrier just receives to become way too significant. But however, I actually don’t know what I’m accomplishing apart from what I’ve go through right here and elsewhere…
three) I decide to tapcon/powder nail with the OSG and XPS to the floor. Is there a rule for how deep to the concrete the screw/nail really should go?
Softer acrylic sealers normally require frequent maintenance with many coats of a sacrificial floor finish, or wax, to forestall dress in and black heel marks. Check out this comparison chart of concrete sealers.
David – The reality is there are plenty of solutions to insulate a basement slab. The sleeper Variation operates very well when You will find a chance of some h2o.
Another significant component is solids content. Most two-portion polyurethane sealers are large in solids, above fifty five%. The higher solids content material can make them fewer capable to penetrate the concrete area, Consequently requiring additional surface area profiling to market adhesion.
Todd — Scanned in teh FH posting, but see no way to attach it into the responses. In essence, the creator recommends that when finishing internet a basement, adhere to the following method for the floor:
You may well be proud of the colour after only one while. Each and every surface area will penetrate in a different way so there isn't any proper period of time to wait apart from just when you're satisfied with the seem of it.
If your float angle is just too steep, you’ll plow the damp concrete and build lower places. A few or 4 passes Together with the bull float is generally adequate. An excessive amount of floating can weaken the floor by drawing up excessive drinking water and cement.
In case the broom starts to bounce while you pull, lower the angle on the deal with. If possible, broom perpendicular into the path that the slab is most seen. Wavy, crooked broom strains are less apparent that way.
Put together your subbase. Your subbase is an additional term for virtually any content on which the concrete rests. Ordinarily, granular fill or road base is utilised to be a subbase, Even though in some uncommon scenarios, soil itself can be used if it is extremely compacted and secure.[one] The soil beneath your subbase is termed your subgrade, and also your concrete is simply going to be as potent as your subgrade.[two] Give it some thought: When your subgrade shifts, craters, or or else moves, the integrity of your respective concrete will likely be compromised.
This offers you concrete greater structural integrity. Wire mesh might help guard small cracks developing and spreading, together with present stability throughout two axes (wire mesh is welded, wherever rebar is often tied jointly).
David – I wouldn’t place them about the laminate. Nonetheless, I do think putting it above the Delta-FL would be Alright. Does the specification for it mention what type of sub-floor restrictions if any it's got?
