Slate Sealer / Re: Slate Sealer Discusion
« Last post by Tex Rowe on October 16, 2017, 05:38:54 PM »
Hi John,
best place to start is our Slate sealer section here:
https://cswcoatings.com.au/product-category/slate-sealer/
as we supply quite a few different products.
First step is to determine if wishing for a Film Forming or Penetrating sealer. You can read about the differences here:
https://cswcoatings.com.au/film-vs-penetrating/
Please note: A product like our Protect & Enhance (film forming) is a popular choice and may help slow down further deterioration though will not help with existing delamination/deterioration.
Any further questions please do not hesitate to ask.

Have laid a slate tiled patio some months ago and some of the tiles are delaminating a little following very hard and frosty winter. I believe it needs sealing please advise which of your many products you recommend for best effect, longevity and DIY application it is an area 6 x 7 metres

Hi Rob,

Am i right in doing the  following
1. Pressure clean 3000psi
2. Two coats penetrative sealer premium
It is important to illustrate that a penetrating sealer like Penetrating Sealer Premium is oil repellent which is typically not the first preference for a garage floor. Applicators typically opt for an oil resistant coating like an epoxy found here:
https://cswcoatings.com.au/product-category/concrete/2-pack-epoxies
So a penetrating sealer is repellent whereas an epoxy is resistant. This is a very important distinction if main preference is for oil protection.

1. Do i have to acid wash or will pressure clean do it
2. Can i paint it afterwards or is it not necessary with the sealer. Better still does sealer come in colours
As far as pressure cleaning or acid etching our products preparation is consistent with most other products and best to see our Preparation Guide here:
https://cswcoatings.com.au/preparation/
The epoxies come in colours though a penetrating sealer being sub-surface is close to invisible commonly called "natural look". You would not need to mix products. Best settle on 1 product only.

Concrete Sealer / Re: Urethane sealer on top of penetrating sealer?

Thanks Tex for the quick answer.
My sealer was quite heavily built, so I will try the xylene bath.

A film forming coating like the Urethane can be applied over a penetrating sealer providing penetrating sealer has not been highly built. In addition, if a solvent based film forming coating is applied over a water based penetrating sealer, the solvent is best applied by "floating on" or lightly applied not to agitate existing water based sealer. This of course will also depend on how much of existing sealer is present. If concerned existing sealer is excessive you could do a light solvent bath with xylene to remove as much of existing sealer residue as possible.

Concrete Sealer / Urethane sealer on top of penetrating sealer?
« Last post by Pierrick on September 17, 2017, 07:45:43 PM »
Hi,

I built a concrete benchtop, and sealed it using the "Penetrating Sealer Deluxe" for benchtops. However, I'd like to get a better stain protection, so is it possible to apply a urethane sealer on top of it? If so, is there any special surface preparation that is required?

Thanks

Hi, Im looking to seal a fast food drivethru. Im not quite sure what to use to seal the concrete in such a high traffic area. Im thinking an epoxy.
Yes you are correct in that an epoxy (2 pack) is the first choice in a commercial high traffic application. As most 2 packs are not UV stable this narrows down product selection to a 2 Pack Urethane which is 100% UV stable and non-yellowing.
So if area is exposed to UV light please see:
2 Pack Urethane
https://cswcoatings.com.au/product/2-pack-urethane/
In addition (to be determined by applicator) it is always preferable for external coatings to lay a single coat moisture barrier like below first:
Water Based Epoxy

Just wondering if it is much more difficult to apply a clear one as opposed to a coloured one?
Slightly as clear coatings will typically show slab related issues like rising moisture etc.

I have been asked to quote a apartment building , Stairs , Landings , Walkways 160 SQM approx.
I am a professional floor coating applicator and lay a wide range of flooring products but as some of the products are quite expensive I was looking to give some more cost effective options.

There is a previous coating on this concrete which is either worn or peeling . What is the recommended preparation? Pressure clean or Grind?

What is your products adhesion to other coatings like ? Do you have pull off test data ?

And what product do you recommend? Will need to broadcast non slip into it and needs to be UV stable
