How To Renovate Your Patio
Lets Renovate Your Patio
Patio renovation is an easy DIY task that can be completed in a day with ease, with this step by step guide you will end up with a good finish that will last for years and at little cost.
Break out the angle grinder you will need a stone disc or a diamond disc (don’t forget your dust mask and eye protection) so you need to remove all the old grout from between the paving slabs, if you don’t have an angle grinder you can complete this step with a hammer and chisel it will just take a little longer. If you have never used a grinder have a play on some scrap bricks first to get the feel of it, so carefully grind out to the depth of the blade, try not to catch the slabs if you can, take your time to get all the old mortar out. you should now be left with a nice raked out joint.
Its jet wash time, blast the slabs with your jet washer (KARCHER K4 REVIEW) to remove ant algae and dirt also blast the now removed grout lines this will remove any dust and give a nice clean crevice to re point later. I use the Karcher K4 with the dirt blaster lance but any pressure washer will do the job just fine don’t forget blast out all the loose mortar and get all the dirt and algae off the slabs so there nice and clean.
Any loose paving slabs will need to be lifted and re laid, so once lifted remove any old cement from under the slabs, you now need to mix up some cement to fix the slab back down
Your going to mix up some cement to re lay the loose paving slabs your going to need sand and cement, now for this job any sand will do the job, you want 4 parts sand to 1 part cement or you can use pre mixed sand and cement and just add water, mix it in a bucket or wheel barrow you want the mixture to crumbly enough so it holds together, put 4 or 5 small spots and push the slab down onto the spots and leave it to dry if you have lots of loose slabs it may be a good idea to do this job the day before your planning on re pointing.
Your loose slabs should now all be fixed back into position, all the slabs are clean ready for pointing.
Cement Pointing Mix
At this stage its important to get the colour of the cement mix consistent so i would recommend you use a pre mixed sand and cement so all you do is add water this does work out slightly more expensive but you will get the colour correct. this mixture wants to be like bread crumbs not wet or its will stain your slabs. don’t worry if you have mixed it to wet just add more sand powder this will dry it up a little. Also if you find that the mixture is starting to go off in your bucket as you are working you can add a little water this will not be a problem.
Step 4 Continued
Use a large trowel and a pointing tool and push the mortar between the slabs get as much in as you can don’t worry about the finish at this stage as you will brush in flat later, continue over the whole of your patio, mix up a bucket full at a time, because you have mixed the mortar crumbly you can now see thats its not marking the slabs, take your time and smooth it out trying to get the finish flush with your slabs or if you prefer a slightly raked out look finish the mortar joint slightly lower than the slab.
You should now have completed all the pointing and it wont look that good what i mean by this is you will have bit of mortar all over your slabs and some of the joints will have lines that your pointing tool has left this is not a problem, now get your self a 1 inch dry paint brush and start from the first slab you pointed and gently brush over the mortar to create a flat finish, this will iron out all those lines you left with the pointing tool. once completed don’t try to sweep the loose mortar of the slabs wait till the mortar has dried (over night) now you can sweep the paving slabs.
You should now have a nice renovated patio that you can be proud of that will last for years, just before the summer kicks in give it a quick blast over with your pressure washer and light the BBQ get your friends over and enjoy and all that cash you have saved can now be spent on a few bottles of wine if thats your thing.
