Hi bagpu55, thanks for your comment, you will find that the level of scratches that come through on the sealer will depend on the type of gloss sealer used. Polyurethane or solvent based sealers last a lot longer and are much more durable, even with animals present. Having said this, the negatives are that solvent based products take some time for the strong smell to escape in a confined environment and are not the most eco-friendly of products. And eventually the scratches will come through particularly in high traffic areas. As for the dust, the gloss will show it a bit more. Based on the fact that you do have a number of animals in your home, you probably will not regret going with the matt finish. The concrete won’t have the ‘wet’ shinny look, but you also won’t be sitting on your couch possibly looking at a lot of scratches on the floor when the light hits it just so. A possible compromise is a satin finish sealer. It will provide some shine and enhancement to the floor without showing as many scratches. I hope this helps you out a bit. Good luck with your choice and post some pics of what your finished floor looks like. Always great to see the finished product!

Well it's is simple, as we will now have concrete floor that get huge amount of winter sunlight in that main living room area our thermal mass figure went up. with the use of phase change material in the roof it to give a thermal mass effect but lot less weight. What it does is stores the energy/heat and transfers it back into room a night. You must realise that this is a very exposed site and we had to get min 6 star rating. Our insulation goes like this from roof down 1, R7 Rock wool batts 2. 90mm Phase change Material 3. to support pcm you have to use 12mm ply sheeting in place of plasterboard 4. Float concrete 5. Electric in slab heating 6. Precast tilt, but played down slabs Underslab 7. R7 Rock wool again 8. 75mm foam batts 9. Reflective foil 10. Box in around steel and make air tight as possible Also all the glass is double glazed, argon filled and thermal shield. We had all that minus pcm and failed because standard way of accessing doesn't have it in calulations. i had to go and show council a sample of the stuff an how it works. This is not cheap but we can just about say that room will sit at a constant 21 to 24 degrees all year around without need for air conditioning . Phase change article

Hi Chris The cheapest option is Grind & Seal, but we usually recommend Mechanically Polished Concrete for inside of a home. This is by far a better option, if you were to go for a Matte or Satin finish it is less expensive than a higher gloss finish. Mechanically Polished Concrete does not have a top coat sealer requiring drying and curing time and does not need re-applying in the future which will save time and money in the long run. Because Polished Concrete does not require drying or curing time it can be used as soon as the process is completed unlike the Grind & Seal option. All floors are slippery when wet, a non slip agent can be added to a top coat sealer which would be the Grind & Seal method which we do apply in a shower area if there is not a shower base. Polished Concrete in Matte and Satin finish does have a very good slip rating, has no grout lines as with tiled floors where dust can get trapped therefore it is a wonderful easy to clean flooring solution. Hope this helps, I have provided some details regarding the 2 main processes below There are 2 different finishing processes / methods that are commonly called Polished Concrete, they are very different so it is important that you know the difference & which process/method you want and which is being used on your concrete Polished Concrete - 12 to 17+ step process During this process the concrete is ground to the desired level of stone exposure. After grinding the concrete surface, the Polished Concrete process begins. This process has a densifier applied in multiple stages that is absorbed into the concrete which hardens and strengthens the concrete. A Polished Concrete Floor is Polished in Multiple stages in a Refining Process using diamond tooling & resin pads. A penetrating sealer is applied in the final buffing stage to complete the process The "Polished Concrete" process has "NO TOP COAT SEALER" applied therefore there is no drying or curing time required so your space can be used as soon as the process is completed Grind & Seal (a 3 to 4 step process) This is NOT Polished Concrete. Grind & Seal is often referred to as Polished Concrete, this is the cheaper substitute that gives a "Polished Concrete Look" With the Grind & Seal method the concrete is ground to the desired level of stone exposure and a TOP Coat Sealer is applied such as water based, solvent based, urethane, acrylic or epoxy requiring 5-7 days to dry & cure

Few things 1. Still not enough space in the store for a bathrub. 2. I will loose the storage space, storage is very important with growing kids, this way i will have a nice big store room to store. 3. Cost and risk - to run drain i need to cut a lot of concrete and you dont know if there are beams underneath, cutting the concrete slab all the way to store is like cutting the the house by half. There is same risk involved when i remove that single brick wall for the new bathroom,. but i am planning to do another wall first then remove this. 4. Upstairs bathroom is big enough to accommodate all - its a 2030 x 3600 in size 5. The hot and cold water coming behind the wall(bedroom1) where i put the new bathrooms, so just need to drill it through the brick. I know either way i have to cut a lot, one is to cut the concrete slab, other is to remove a brick wall. I thought about putting one outside, but then i have to involve a surveyor, council etc. to much time consuming that way.
