How To Fill Holes In Interior Concrete Walls?
- Joe Thomas
Hydraulic cement would be a sensible option for fixing tiny holes in concrete, given that this is its intended purpose. Be cautious to moisten the hole before filling it with cement and leveling it.
How can gaps in concrete walls be filled?
@dustbunny228: Welcome to the Bunnings Workshop community! It’s incredible that you’ve decided to join us, and we appreciate your inquiry regarding plugging holes. Best wishes on your purchase! This must be a moment of great excitement for you. You can utilize Timbermate 500g Concremate Expanding Cement, which will be far stronger than the existing plaster filler.
However, I would advise avoiding drilling holes in the exact same locations, and if you need to install something nearby, simply offset the hole by around 10mm. The cement filler may be applied to the holes with a scraper, and then sandpaper can be used to smooth it out. To mix the repair with the surrounding area, you can apply Selley’s RapidFill.
Please contact me if you have any inquiries. Mitchell

If the hole is deeper than 1 in (2.5 cm), you should use a mortar mix including crushed stone aggregate. Treat holes as soon as they are discovered to avoid further water and rat damage to the concrete and entry into the residence. Before washing the concrete, don a dust mask and safety glasses. Always use safety clothing before working on the damaged area, since it is a dusty operation. When chipped, concrete generates a great deal of dust. This also implies that little shards may return to your face while you work. Additionally, have rubber gloves on hand, although you won’t need them until you begin mixing new concrete.
- If you are working indoors, provide as much ventilation as possible to combat the dust. Open doors and windows in the area. Turn on any available ventilation fans and then vacuum up the dust.
- Consider shielding neighboring areas with a plastic tarp, since concrete can generate considerable dust.
2 Remove loose concrete from the hole using a hammer and chisel. Remove the broken and disintegrating concrete surrounding the hole. Additionally, attempt to establish a sturdy, level surface for the new patching material by flattening down the bottom of the hole.
- If the hole is already deeper than 1 inch (2.5 centimeters), you should not attempt to make it deeper. Instead, thoroughly clean the area and select a suitable patching substance.
- Make the bottom of the hole somewhat larger than the top, if feasible. You may do this by holding the chisel diagonally and chipping away at the hole’s bottom edges. Increasing the size of the base helps to secure the repair to the existing concrete.
- To remove damaged concrete, a circular saw with a masonry bit might also be used.

If you have a shop vacuum, utilize it to collect the trash more quickly. Ensure that the hole is devoid of any debris before attempting to fix it. Eliminate any debris to prevent it from interfering with the repairing material. Any remaining debris will degrade the patch! 4 If loose particles must be removed from the concrete, wash it with a cleanser. Purchase a concrete cleaner from a store and pour it into the hole.
- For the purpose of preparing concrete, commercial concrete cleaners are highly beneficial. They remove stubborn stains, grime, and debris that might compromise the new patch. Debris alters the nature of the concrete, so the patching material may not adhere correctly or be as durable as it should be.
- If the concrete hole appears clean, simply spritz it with water.
5 Rinse the concrete with clean water and allow it to dry completely. It should be sprayed with water from a hose or poured over with water. Ensure that all debris is removed. Use clean cloths or paper towels to absorb the excess moisture. Wait until all standing water has evaporated before trying to fix the hole.
This may take thirty minutes to an hour, depending on the weather and the amount of remaining water. Any remaining water will degrade the concrete repair in the same way that loose debris would. Allow it ample time to dry! 6 Spritz the hole with water if it is deeper than 1 inch (2.5 cm). The removal of material from a huge hole is frequently a challenge.
In most circumstances, you can remove the majority of particles with a brush or vacuum. If that is not possible, the hole should be filled with water. Spray it with a hose or fill it with water until it overflows to remove debris.
- Remember to enlarge the hole by first removing loose concrete. Typically, this will allow you to brush or vacuum the particles away.
- Continue to wash out the hole until you are certain it seems clean. Ensure that the water remains devoid of any debris. Then, absorb as much water as possible and let the hole to dry naturally.

- A 60 lb (27 kg) bag will fill a 1 foot (0.30 m) by 3 foot (0.91 m) by 2 inch (5.1 cm) hole. Unless you are performing several repairs, a single bag should enough.
- To manufacture your own mortar, add one part Portland cement, three parts masonry sand or gravel, and one part water.
Apply a bonding agent to the concrete with a brush. A bonding agent is a liquid that binds fresh and old concrete together. If you have not already, don work gloves. Use a paintbrush to distribute the paint throughout the hole. Coat the bottom and sides of the hole with a uniform coating.
- Note that the bonding agent can frequently be applied after the concrete has been poured into the hole. Refer to the manufacturer’s instructions for further details.
- It may also be possible to include the bonding agent into the concrete. Typically, 50 to 80 percent of the water is replaced with the bonding agent.
- If the bonding agent is not used at this time, softly dampen the concrete with a moist sponge. Ensure there is no water standing in the hole.
3 Pour the mortar mixture into a pail of water. Add water to the mixing bucket before dropping in the mortar to limit the quantity of dust generated. Use 10 fluid ounces (300 milliliters) of lukewarm water for every 5 pounds (2.3 kilograms) of mortar mix. If too much water is added, the mortar will be too soupy and will not harden correctly.
- When mixing mortar, err on the side of caution. You may add more water at any time, but you cannot remove it. The only solution for a runny mixture is to add additional mortar.
- Check the manufacturer’s guidelines for the amount of water to add. Incorporate the liquid bonding agent if you intend to add it to the mixture.
- When mixing mortar, be careful to use safety glasses, a vented mask, long pants, and gloves.
4 Mix the mortar for three to five minutes until a thick putty is formed. Using a hoe or other implement, stir the mortar in the bucket. A paddle attachment, which is a metal mixing rod that connects to the end of a power drill, can also be used. Check the consistency of the mortar while continuing to mix it. 5 Apply mortar using a trowel to the hole. You may spread the mixture over a tiny hole with a putty knife. Utilize the instrument’s tip to work the mixture into the hole. First, cover the sides of the hole, then begin filling the middle. Try spreading the mortar to a thickness of 14 inch (0.64 cm) each time.
- If you’re dealing with a hole that’s more than 1 in (2.5 cm) deep, layering mortar is only truly beneficial. If you are repairing a shallow hole, you may as well do it all at once.
- Maintain the level of the patching material with the surrounding concrete. Adding more than necessary is acceptable. You will have the opportunity to remove any extra before it dries.
- Fixing a wall or other vertical surface is comparable to patching a hole in the ground. First, pack the mortar well into the hole, then add more layers. It will remain in position.

- The board will catch extra mortar, allowing you to level the patch with the surrounding concrete and smooth it out.
- For holes on vertical surfaces, consider dragging a board over the hole and then troweling over the patch again. If you cannot use a board, you may substitute a trowel or float.
2 Apply a trowel or float to the leftover mortar and smooth it out. Try using a float, which is a tool with a flat bottom meant for smoothing concrete, on the mortar. Several times, move the tool back and forth across the mortar. After a few passes, the mortar patch will seem flat and will integrate well with the adjacent concrete. Ensure that the repair is flush with the surrounding concrete. Utilize a wooden plank to remove any extra mortar before allowing it to set. Cover the patch with a plastic sheet to safeguard it against harm. Before the patch has had a chance to heal, it will be rather susceptible. Obtain a concrete insulating barrier, put it over the spot, and secure it in place with pins. Weight it down with bricks or other hefty things. 4 At least six hours later, spray the affected area with tepid water. Rapid-drying patching material typically solidifies within four to six hours. After the plastic sheet has hardened to the touch, pull it up. Apply lukewarm water on the concrete using a spray bottle or a hose. 5 Continue to sprinkle the concrete twice each day for a minimum of seven days until it dries. Consult the manufacturer’s instructions for further information regarding the curing speed of several quick-drying materials. Set aside a certain period each morning and evening to ensure that you do not forget to spray the mending material while it dries.
- Some products may demand that you cover the affected area for up to 28 days while spraying daily. Even while this may seem like a long time, if the manufacturer suggests it, it is worthwhile to do so.
- After the concrete has cured, remove the plastic covering and do a quality inspection. It must be flush with the surrounding concrete and have a brittle texture.

How can a wall hole be repaired without drilling?
How to patch large wall gaps – As most fillers are designed for the surface, you’ll need a filler designed particularly for the depth of the hole. Deep fillers are more robust than superficial fillers and are intended to prevent the condition from deteriorating.
- Clean the hole thoroughly, removing any loose debris.
- You may accomplish this using a scraper or a fine brush.
- Utilize a tool with a flat edge to press the filler into the fracture.
- It should be slightly overfilled to ensure that it is filled to capacity.
- It was smoothed using a moist knife.
- Check the directions to determine the drying time, which should normally be one to two hours.
Once it has dried, sand it until it is flush with the wall. If you are filling a hole that is more than 50 mm deep, you must apply the filler in layers. Always wait for the first coating to dry before applying a second. To assist the repair blend in with your paint, apply a mist coat.
