If you’re thinking about making improvements to your home, it’s only reasonable to become familiar with the ins and outs of the requirements to make the project a success. Not just the cost involved to complete the project, but also the duration it’ll take to complete the job and lots more. When it comes to the installation of wooden flooring, there’s a need to find out whether or not an underlay is required for the task. In this article, we’re going to consider this in order to ensure that you’re on the right track. Let’s take a look!

First and foremost, underlays are common with carpets as they allow for an even surface with no lumps and bumps. It also provides a deeper barrier between the carpet and the floor as carpets, themselves, aren’t particularly thick enough to provide adequate comfort when walking on them. Underlay also helps improve insulation which in turn, helps cut down your energy bill. So, are underlays also needed with wooden flooring?

In general, wooden flooring does not really need an underlay. This is due to the fact that they’re perfectly comfortable to walk on without the need to add an extra padding underneath. However, the subfloor will have to be made prior to the installation, as a result, an underlay is needed at all there. With that in mind, it’s highly recommended to make use of an underlay when installing a boarded floor to a wooden subfloor mainly due to the fact that it’s able to provide a much-improved insulation. When it comes to wooden flooring, it’s always best to go for quality rather than looking for ways to cut corners. If you’re able to go for the best project with professional installation and little extras like undelay, you’d notice and enjoy the long lasting nature of your wooden flooring immediately after installation.

Installing wooden flooring is a quite simple process, however to get it right the first time, there are very essential preparations that must be made. These includes determining the site is in the best condition before installation, removal of all floor coverings and underlay for a more stable and durable installation and incorporation of the right expansion gap of about 10mm to 12mm which would be maintained around the floor’s perimeter.

Wooden floor fitting can be done on two types of sub-floor - Concrete and Plywood. To install onto concrete, you can follow the guide below:

• Incorporate flexible wood on concrete adhesives.

• With the help of a 3mm toothed trowel, spread above 2 board widths of adhesive along the starting wall sub-floor, beginning at a corner of your room.

• Position the first row of flooring into the area that is glued using the tongue facing opposite the wall.

• Put 10mm spacers against the wall to see to the consistency in expansion gaps.

• Make sure the joints are at a minimum of 150mm apart from the first row when fitting the second row.

• Utilize pre-cut smaller boards if you’re to start a new row with staggered joints.

• Continue with this nailing method and make sure the 10mm expansion gaps are consistent around the floor’s perimeter.

To install onto plywood, you can follow this guide:

• Make use of a porta-nailer.

• Position 10mm spacers against the wall - parallel with the installation direction.

• Fit the first row using the tongue facing opposite the wall and with the help of the porta-nailer or flooring nailer.

• Lay the second row and make sure the short end joints are at a minimum of 150mm apart from that of the first row.

• Utilize pre-cut smaller boards if you’re to start a new row with staggered joints.

• Continue with this nailing method and make sure the 10mm expansion gaps are consistent around the floor’s perimeter.

1. Calculate the surface area for your decking Multiply the length (L) of your decking area by the width (W): L x W = Decking Surface Area (DSA) in m² 10 x 6 = 60m²
2. Work out the coverage of your deck boards Add your deck board width (DBW) to the expansion gap length (EGL), then add the deck board length (DBL) to the expansion gap width (EGW). Then multiply these numbers. (DBW + EGL) x (DBL + EGW) = Single Board Coverage (SBC) 0.144m + 0.005m = 0.149m 2.4m + 0.003m = 2.403m 0.149 x 2.403 = 0.358m²
3. Calculate the number of deck boards you need Multiply the SBC by 1.1 to allow for 10% wastage. Then, divide the DSA by the SBC. DSA / SCB x 1.1 = Total number of boards required 60m² / 0.358m² x 1.1 = 184.36 boards – so round up to 185 so you’re not left short.

• The shed doesn’t cover more than 50% of the garden
• It’s not in front of your house
• The shed is single-storey with eaves no higher than 2.5m and the overall height is no taller than 4m for a dual-pitched roof, or 3m for any other type. If it’s located within 2 metres of your property’s boundary, it mustn't be more than 2.5m high
• There’s no veranda or balcony
• The floor area is no bigger than 15m² - up to 30m² may be covered under Permitted Development if other conditions are met
• The shed is for domestic use only by those who live in the property and there’s no sleeping accommodation – that means you can’t run a business from the shed unless you apply for planning permission

• If you live in a listed building, you’ll need Listed Building Consent before you can build a shed in your garden
• If you live in a conservation area or similar, the maximum area of ground covered by outbuildings, pools and enclosures situated more than 20m from any wall of the house mustn’t exceed 10m² if they’re to be considered as a permitted development
• If you own a piece of woodland, you must seek planning permission for any permanent structure
• In Scotland, you’ll need planning permission if any part of the shed comes within 1m of a neighbouring property or is more than 2.5m high
• In Northern Ireland, there are rules about how close your shed can be from a road that passes by the back of your house. It’s best to check for clarification

Two of the commonly used terms in the UK and Irish construction industry is “First Fix and “Second Fix First fix encompasses all the work required to take a building from foundation to stroking plaster on the interior walls. This comprises of building walls, floors and ceilings, and implanting cables for electrical supply and pipes for water supply.

Some claim that First Fix starts after the shell of the building is complete, and ends when the walls are plastered. Some of the elements in the first fix are as follows.

• Drain runs: must be downhill and straight

• Spare conduits: drawstrings

• Soil pipes

• Copper pipes

• Normal pipes

• Doorbell

• Door frames

• Pocket doorframes

• Stairwell

• MVHR (mechanical heat recovery ventilation runs)

• Push-fit or other plastic piping

• Electrical back boxes

• Electricity cable runs

• Telephone, data and audio-visual cables

• Socket location

• Security

• Fire alarm

• Sound insulation

• Plasterboarding

It is to be kept in mind that the list goes on as there are several things that you can do when you are building a house from scratch and it is impossible to cover each and every aspect in detail.

The second fix includes all the work after the plastering of a complete house. These include linking cables to the electrical fittings, coupling pipes to the baths and sinks and fitting doors into doorframes. Second fix work requires a tidier finish than the first fix.

Carpenters, electricians and plumbers get a proper idea on the division of work. They will also be able to visit the construction site at different times.

Project managers can simply report it as the "first fix complete" or "the second fix 50% done" and others would very easily understand.

Regardless of the fact that a construction company might specialise in a certain form of fix, be it the first or the second, they are obligated to have a rudimentary understanding of both and are required to perform them from time to time.

Though both solid wood and engineered wood can be installed on a concrete sub-floor, the processes are quite different from each other. Solid wood is produced from a single plank of wood which can be reactive to both temperature and humidity changes which is capable of making the wood expand or contract. Hence, the different approach to solid wood and engineered wood flooring installation on concrete. Here, we’ll discuss how you can lay solid wood on your concrete.

First and foremost, you’d have to determine the method you’ll use to attach the planks to the floor. Is it floating whereby you only have to lay the wood flooring on the concrete after fitting the right underlay? You can also go for the most popular installation method which is gluing your floor with a flexible wood adhesive (to be applied to both the boards and the sub-floor). Or perhaps you’d prefer to use the traditional method of nailing the boards to the concrete (the nails will be covered as you lay the subsequent planks and the groove locks with the tongue).

After making this decision, you’d have to ensure that the sub-floor is well prepared for the installation. This implies checking the wood’s moisture content (mustn’t exceed 7 to 8 percent). Also inspect the floor to ensure its neat, if not, clear out the dirt or debris and make sure the surface is flat to avoid post-installation problems.

In the event whereby you discover a high moisture content, you’d want to acquire a damp proof membrane. This will not only enhance the floor’s stability, but also prevent shrinking or warping of the wood due to changes in humidity or temperature.

It is crucial to note that the preparation of the sub-floor is equally as important as the laying of the planks as this can go a long way to improve the durability and strength of your floor. Click here to learn more about wood flooring.

1. How to build a shed base out of paving slabs
   • Mix sand and cement together to make mortar or use a pre-mixed one
   • Use a trowel to lay mortar for 1 slab at a time on the sub-base and lift a damp-sided slab onto the mortar, using a piece of timber and club hammer to tap the slab into position carefully. Continue to lay the first row of slabs
   • Make equally-sized spacers in all the joints in the slabs to ensure they’re the same size, checking it’s level as you go along
   • Next lay slabs along the two adjacent outer edges, filling in the central area row by row
   • Leave the mortar to set according to the instructions or for at least 48 hours before filling in the joints with mortar or paving grout
2. Building a shed base from concrete
   • Create a wooden frame around your shed base area (also called formwork) to stop the concrete from spreading
   • Mix pre-mixed concrete with water or use 1 part cement to 5 parts ballast
   • Wet the sub-base using a watering can with a rose on the end
   • Pour the concrete onto the framed base starting in one corner
   • Push the blade of a shovel up and down in the edges of the concrete to get rid of air bubbles
   • Use a rake to spread the concrete, leaving it around 18mm higher than the top of the frame. Work in sections of around 1-1.m²
   • Compact the concrete using a straight piece of timber that’s longer than the width of the base. Move the timber along the site, hitting it along at about half of its thickness at a time until the surface is evenly ridged
   • Remove excess concrete and level the surface by sliding the timber back and forwards from the edge that you started. Fill in any depressions and repeat until even
   • Run an edging trowel along the frame to round off exposed edges of the concrete and prevent chipping
   • Cover the concrete with a plastic sheet raised on wooden supports to allow slow drying. Weigh it down with bricks
   • Once the concrete is set, you can install your shed and remove the wooden frame with a crowbar

• Paving slabs – old or cheap ones are fine
• Timber for the frame and legs
• Type 1 MOT hardcore

1. Mark out the area as we explain in ‘How to lay decking’. Then, dig to 200mm below where you want to surface of the decking to be.
2. Add a 50mm layer of hardcore and make sure it’s compact.
3. Build the decking sub-frame as we describe in ‘How to build a deck frame’.
4. Lay out paving slabs along the edges and in the centre of the area. This will help to spread the weight of the decking.
5. Set the decking frame on the slabs, checking for high or low points and adding off-cuts of timber where needed. Don’t forget to sand and seal these off-cuts with decking preservative.
6. Add your joists and then the deck boards, leaving the recommended gaps of expansion of between 5-8mm.
