Either way, you need to make sure that there is no dirt left on the surface where you are going to put the drywall tape. 2. Apply Joint Compound on the Wall Put this in the context of an exposed wooden window frame in a bathroom that has been plastered right up to it.

This method is normally used where the area surrounding foundations is so unstable that piling cannot be used for fear of further disrupting any supporting base and causing more damage. Soak the drywall tape in water before applying it on the surface. This will eliminate the risk of bubbles and wrinkles appearing on the tape. And will help you align and apply the tape easily. Sections of ground are dug away from under the concrete foundations and a mass fill of concrete is poured under the existing foundation. Different people get used to the different materials and they give preference to their favorite ones over the other. This is why you’ll see professionals making contradictory statements regarding drywall tape types. Mould flourishes in conditions of high humidity, poor ventilation and on surfaces with a high moisture content. It can be very destructive to paint finishes and needs to be eradicated before applying paint. Treat affected areas with Weathershield Multi-Surface Fungicidal Wash. Leave on the surface for 24 hours, scrub with a stiff brush (not metallic) or nylon abrasive pad, and wash down to remove residues. Allow to dry thoroughly. If necessary, repeat the treatment. Use two coats of Dulux Trade Mouldshield Fungicidal Eggshell to help reduce the likelihood of mould returning.

Types of Cracks

How to correct it depends on which of the above caused it, but as a general rule of thumb, you should rub down the affected areas and apply two thin coats of paint with a roller. If the crazing has been caused by application of matt onto silk paint, apply a coat of Dulux Trade Vinyl Soft Sheen. Where the crazing is really severe, it may be necessary to fully strip the wall down, apply lining paper and re-paint.

Any number of geological events could trigger earth movement, but it is the continuation of the movement which should cause concern. Grout is pumped into these holes and left to go hard. As the grout dries in the holes in the slab as well as in the ground, the slab and the piles become as one. Internal Doors – When serious subsidence or foundation issues occur they can cause your property to effectively twist and bend. When this happens, items such as door frames that need to be square so that the actual door fits within it, are pulled out of shape making the door tight and stiff to open and close. Additionally you may also notice gaps around the door and frame At the other end of the scale there could be bigger problems with foundations where they need underpinning in some way.An aged tree’s root system can be twice as large as anything visible above ground and due to this root mass can absorb a considerable amount of moisture causing soil shrinkage. Sometimes the foundations themselves may stay relatively stable but (especially in clay soils) the compacted ground under the floor slab may drop when it is too dry or the slab has been laid on a sub-base which has not been properly compacted or contains organic material which has decomposed. The second type of steel pier is called a “push pier”. These are normally galvanised steel sections that are driven down into the soil using a hydraulic ram to provide the stable base for support. If any of these develops a leak then in a very short space of time soil can become saturated around foundations and severely weaken it’s load bearing abilities. Trees This is a step many skip but we consider it to be an important one. Run your hand along the cured compound that you’ve sanded. You should feel no bumps or deformities. Other than the texture, the compound should feel just as flat as the wall surrounding it.

If there is a gap that needs filling or if the joints are not flush, it's time to apply drywall tape. If your walls seem floppy and wavy, applying drywall tape will help secure them in place. Apply at least one layer of tape to the joints and create smooth, flat seams. The joint compound in place provides some strength, but it's taping that really holds things together. What happens if you don't tape drywall seams? Once the resin has set and the length of the gap has been stitched it can then be filled using a soft mortar mix. Wouldn't it be nice to start every job from scratch? Unfortunately, professional decorators know that this is not always the case, and that inheriting mistreated and damaged walls is all part and parcel of the job. Dealing with damage can be a complex task, so we've rounded up the most common types of problem, and the solutions for each: With concrete, normally a set of reinforced steel bars are then lowered into the hole for additional support and bonding of the concrete and the concrete is then poured in and allowed to set. In the case of any settlement or subsidence issues this will need to be sorted as soon as possible to prevent any further damage to the property.Once complete, leave for a few days to ensure that it cures correctly and once it has you can then sand any bumps or raised edges until they are flat.

The requirement of mold resistance comes along with the moisture resistance. Because humid surfaces are prone to mold growth more than the dry surfaces. If you have followed all of the procedures, you just need to wait for the joint compound to dry out. Remember that if you leave any space without applying joint compound underneath the tape, it will come out of the wall after a while.

Cracks in Walls – are They Still Active?

After an even bead of drywall joint compound, place the tape on the surface. You should place it in a manner so that there is no bubble left below the tape. 4. Joint Compound on the Tape Application of paint before caulk is fully dry. Ensure that caulk is dry throughout (not just surface dry) before painting over. Wall Tie Failure – As mentioned above, we have a full and detailed project on how to replace wall ties – this can be seen here Additionally as roots grow and move they can also cause loosening and movement in soil. Prolonged Drought
