Behr Deck Over Concrete Patio – Let’s begin first we should appraise the area is it a turf or concrete base beneath the decking a turf base will have to be dug off and membrane put beneath the decking it is possible to and may put membrane under any decking project to halt any weeds penetrating through, where would be the damp course levels even as we do not want when higher than the damp course ideally when needs to be two bricks below the damp course. And can there be any drain access points beneath the decking because they will require an exclusive decking drain cover. Always remember the decking boards go horizontal along your home. Always remember decking higher that 1.2m off the walk-out will require planning permission
Now we have assessed these factors they will decide the height of when and any special requirements that have to be incorporated in the decking project. Estimation of materials first appraise the area from the decking i.e 4.8m x 4.8m = 23.04sq meters. Then employ this equation to calculate the decking boards needed 4800mm / 140mm (deck board width which can be 4.8m long) = 35 decking boards. Add a little for cuts and edges that have to be filled in. Then calculate the strain bearing supports (4 x 2 pressure treated CLS) 4800 / 600 = 8 This the volume of horizontal 4 x 2 pieces needed for your internal structure from the decking as well as the outside from the frame i.e. 4800 x 4 = 19.2m + (8 x 4800) = 58m of 4 x 2. Add some for your cross member struts and positioning pegs (banged and concreted as needed in the ground) about three to four 4.8m lengths should suffice.
Setting up the frame this carried out near or as close on the position from the final deck. Start by cutting the ends from the required wood square this will help while using construction from the frame always cut the pieces of wood the identical length because frame will not be square if your wood is of numerous lengths. Then join the corners from the frame by piloting the holes for your 4 inch screws to be screwed into wood. Once this is achieved you should get the frame square, utilizing an engineers square stick it in a single corner and move until square. Then screw a batten within the corner to keep the corner square make this happen for all those corners. Then measure internally in the horizontal from the frame the location where the load bearers are getting divide this measurement by 600mm this will give you an identical spacing for your struts. Next screw theses in position it’s better to place a length of wood beneath the frame while carrying this out to have the edges to meet. Once this is achieved appraise the cross member struts around three feet is around right for your spacing of the. They go vertically along when frame stepping out then in to enable screwing.
Location of when, get when into position while using help of an friend. Then start within the highest corner of when and bang some cut 4 x 2 (depending around the height of when cut accordingly) in the ground having a large sledge hammer. Once done lift when into position and screw together having a 4 inch screw. Now work along when on the next horizontal corner lifts the corner hence the frame is level and do the identical. Now work over the front have a very slight lean away in the house or make certain whichever way the boards are running tip when hence the water runs out from the surface. Then work your way across when making sure that any weak spot is based on banging a piece of 4 x 2 in the ground beneath it. Once this is achieved test the strength by walking over the struts to show any weak spot don’t get worried excessive because decking boards will strengthen the decking after they are fixed on the frame.
Today we cut and fit the decking boards on the frame. Make sure every one of the edges from the decking are cut square before cutting on the correct length. This will aid construction and overall Finnish from the decking project. Start having a full length of decking making sure the end meets the frame or cut the board on the nearest beam and connect the board having a Paslode nail gun using 50mm nails or pilot and countersink holes and screw the boards screwing is way better long term but nailing is faster and easier. Work along when spacing having a 5mm nail banged right into a piece of 4 x 2, this will ensure the gap remains the identical. Always remember to stagger the joints from the decking almost every other board hence the joints blend in the decking. Once you decking boards are fitted then fit any surrounding decking boards on the edges to cover up any from the frame work and check for just about any boards who have splinters and sand these down if it is possible to.
