Vogliamo impermeabilizzare la parete.

Vogliamo is the 1st person plural form of volere, which means to want.

So vogliamo = we want.

A quick mini-table:

• voglio = I want
• vuoi = you want
• vuole = he/she/it wants
• vogliamo = we want
• volete = you all want
• vogliono = they want

In this sentence, vogliamo is the main conjugated verb.

Because after volere (to want), Italian normally uses another verb in the infinitive.

So the structure is:

volere + infinitive

Examples:

• Voglio mangiare. = I want to eat.
• Vogliamo partire. = We want to leave.
• Vogliamo impermeabilizzare la parete. = We want to waterproof the wall.

This is very similar to English want to + verb.

Impermeabilizzare means to waterproof or to make impermeable/water-resistant.

It is a regular -are verb. Its ending shows that it belongs to the first conjugation.

A few forms:

• impermeabilizzare = to waterproof
• impermeabilizzo = I waterproof
• impermeabilizziamo = we waterproof
• impermeabilizzato = waterproofed

It is a fairly technical or practical word, often used in construction, home repair, engineering, and maintenance contexts.

Yes. Impermeabilizzare is built from impermeabile, which means waterproof / impermeable.

The rough idea is:

• im- / in- = not
• permeabile = permeable
• impermeabile = impermeable / waterproof
• impermeabilizzare = to make something impermeable / to waterproof it

This kind of word formation is common in Italian:

• moderno → modernizzare = to modernize
• reale → realizzare = to realize / to carry out
• impermeabile → impermeabilizzare = to waterproof

Italian often uses the definite article more than English does.

So where English might say:

• We want to waterproof the wall

Italian naturally says:

• Vogliamo impermeabilizzare la parete.

Here, la means the, and parete is a feminine singular noun, so la is the correct article.

You usually include the article when referring to a specific object or a general concrete item in context.

They are similar, but not always identical.

• parete usually means wall in the sense of an interior or vertical surface, especially in rooms or buildings
• muro often means wall in a more structural or solid sense, like a brick wall, boundary wall, or load-bearing wall

In many everyday situations, both can translate as wall, but the nuance can differ.

For example:

• la parete della camera = the wall of the bedroom
• il muro di cinta = the boundary wall
• un muro di mattoni = a brick wall

In your sentence, parete sounds natural if you are talking about treating a wall surface.

Because Italian often leaves out subject pronouns when the verb ending already makes the subject clear.

• Vogliamo already tells you the subject is we
• So noi is not necessary

You could say:

• Noi vogliamo impermeabilizzare la parete

But that usually adds emphasis, contrast, or clarity:

• Noi vogliamo impermeabilizzare la parete, loro no. = We want to waterproof the wall, they do not.

Without emphasis, Italian usually prefers simply:

• Vogliamo impermeabilizzare la parete.

The basic word order is:

verb + infinitive + object

So:

• Vogliamo = we want
• impermeabilizzare = to waterproof
• la parete = the wall

This is a very normal and natural order in Italian.

You could change the order in special contexts for emphasis, but the standard version is:

• Vogliamo impermeabilizzare la parete.

Both the noun and the article would change.

Singular:

• la parete = the wall

Plural:

• le pareti = the walls

So:

• Vogliamo impermeabilizzare le pareti. = We want to waterproof the walls.

This is because parete is feminine:

• singular: la parete
• plural: le pareti

Yes. Depending on context, there are other natural ways to express the idea.

For example:

• Vogliamo rendere impermeabile la parete.
  = We want to make the wall waterproof.

• Dobbiamo impermeabilizzare la parete.
  = We need to waterproof the wall.

• Vorremmo impermeabilizzare la parete.
  = We would like to waterproof the wall.

Your original sentence is perfectly correct and direct. It sounds practical and natural, especially in a construction or repair context.

A helpful approximate pronunciation is:

voh-LYAH-mo eem-per-meh-ah-bee-lee-tsa-RE la pa-RE-teh

A few pronunciation notes:

• gli in vogliamo is a special Italian sound, somewhat like a soft ly sound
• zz in impermeabilizzare is pronounced like ts
• the stress in parete falls on te
• the stress in impermeabilizzare falls near the end: -za-RE

If you want, you can think of the rhythm like this:

vo-GLIA-mo im-per-me-a-bi-liz-za-RE la pa-RE-te

Yes. In this sentence, impermeabilizzare is being used as a transitive verb, meaning it takes a direct object.

• impermeabilizzare la parete

Here, la parete is the thing being waterproofed.

That is why there is no preposition between the verb and the noun.

Compare:

• Mangiamo la pizza.
• Ripariamo il tetto.
• Impermeabilizziamo la parete.

All of these use a direct object.
